(UPDATED FREEZER CHALLENGE--PART 2) GOOLOO GT4000 VS. LOKITHOR J401X
Вставка
- Опубліковано 2 жов 2024
- Today, we revisit the deep freeze test for the Gooloo GT4000 & Lokithor J401X. In the last freezer video, the Gooloo GT4000 was unable to jump start the Cadillac V8 with the preheat technology in the freezer test. We are giving the Gooloo GT4000 another chance to redeem itself in this updated video. We brought the Lokithor J401X into the test to have a comparison angle to the video to see how both units operate in frigid cold, and to see if there are any differences between the two jump starters.
Just to clarify, we did, in fact, have a defective Gooloo GT4000 with the preheat technology. Not activating in below freezing temps in a few different videos. We ordered a new Gooloo GT4000 to verify if we had a defective unit or not, and the new Gooloo GT4000 works perfectly with the preheat technology activating properly. We had a few other viewers mention that their GT4000 was acting the same as our defective unit with the preheat technology, not activating. So obviously, there are a few defective units on the market (like all products). Also, just to clarify, I am not one to bad mouth another company, I just post and review what I experience. Gooloo is an outstanding company that makes great portable jump starters. Unfortunately, a few defective units slip through the cracks every now and then and get shipped out.
I sure hope they got it corrected as I just ordered a gt4000 from Amazon. I was just hoping to get a new one instead if something they rewrapped! Thanks for passing that along. So I should chill the unit and that will test its heating element to charge - again, thanks.
@semlohde1 All the GT4000 units were not defective, I was just one of the lucky ones to have a defective unit. If you want to test the preheat technology, you will need to keep the unit in frigid temps for a few hours before use. Read the manual in reference to the preheat technology. Let me know how yours works.
Finally someone that tests jump starters when they are cold. Leaving it in your cold trunk and then finding you need a jump is when I need it to work the most!
@@stevenle1760 Nobody remembers to take that shit out of their car everytime they go inside when it is -40. 🤣
что бы разморозить надо подержать кнопку boost
Мудак кабеля резанул, нарастил чем нарушил сопротивление!🤣
If it’s the gt4000s then it does not have the heating feature. They have two versions
The Gooloo GT4000 has the low temp technology, the GT4000S does Not have it.
Right that’s what I said just in reverse order.
Just having ordererd the Gooloo GT4000S today, I might be off track.
Isn't there a heating indicator right next to the snow flake icon, as if the snow flake would just be a low battery temperature indicator. Shouldn't that heating indicator come up while actual the pre-heating procedure is active? Also, shouldn't the display show the pre-heating temperature right next to the wattage display?
Both didn't light up during your test.
Checking out the Gooloo US Official Store, it seems that the GT4000S only is equipped with the cold battery warning indicator, while only the GT4000 (without the S) is equipped with the "Most Intelligent Pre-Heat -40°F Start Tech", for whatever reason.
The snowflake indicator means there is low temp technology. The Gooloo GT4000S does Not have low temp technology, the Gooloo GT4000 does have low temp technology. When the temps are too cold the Gooloo GT4000 will display a snowflake showing the unit is cold, then after about 100 seconds the low temp technology is supposed to activate and warm up the unit, then you are able to jump start in frigid weather. The snowflake indicator should not illuminate if the battery is low. If you need anymore info please let us know. But if you live in a cold climate the Gooloo GT4000 has low temp technology, the Gooloo GT4000S does not. Thanks for the comment
@@HM_RELOADED
Thank you for confirming my research. Meanwhile, I cancelled my order. Unfortunately, only the "S" model is available in my country.
@@RECURSIVE_MEMORY_LOGIC Where are you from, if you don't mind me asking?
@@HM_RELOADED
Sorry for the late reply. I live in Germany.
Amazon only sells the GT4000S variant which I returned. Seemed, that the variant with battery preheating is not available in Germany at all. So I ordered a GT4000 at Aliexpress and got it shipped from Poland.
To test pre-heating - I was all curious about it - the unit spent 24 hours in the freezer. Took it one minute to heat its energy cells from -15 °C to +5 °C, while its capacity dropped from 100 % to 96 %. No opportunity yet to jumpstart a car.
Just took the opportunity to upload a short clip showing the procedure:
ua-cam.com/video/TIPc-yZONdQ/v-deo.html
@r.martinlebrecht9987 Thank you. I have seen on other videos how it works. So I must have a defective unit. I know a couple other people who have the same issue as our GT4000. So I guess there are a few defective units out there, just like all products. Unfortunately, there are always a few bad ones in the bunch. I just posted the results from the unit I experienced. My intentions weren't to make Gooloo look bad, but I make videos showing the product I was given.
I appreciate you taking the time to show me the video and how the unit is supposed to work
Your gt4000 isn't preheating. When it is heating a temperature in celsius is displayed and a little heating icon shows up beside the snowflake. Without the booster cables plugged into the unit you need to turn the unit on and hold the boost button, this should enable preheat mode if necessary.
We did that on and off camera, we believe we have a defective unit. We did everything, trust me. Lol. We are in the process of ordering a brand new GT4000 and we want to see what happens to that one. There was one UA-cam video that shows the GT4000 preheating without being hooked up, then i have had other people tell me it shouldnt matter if the unit is hooked up or not, it still should have preheated. But as i said, i usually test things on and off camera extensively before and after making videos, just to share some info. All the other units i have tested with the preheat technology preheated and worked great when they were hooked up to the battery. But we have testes all the units on our channel with preheat technology on and off camera. Watch our newer videos on deep freeze test and the Gooloo GT4000 does preheat when its hooked up, but it takes about 15 to 20 minutes to preheat for whatever reason. Our last 3 videos on the Gooloo GT4000 were the deep freeze videos, the Gooloo GT4000 was able to work in frigid temps, after about 15-20 minutes like i said. The first video the GT4000 was not able to jump start. Thanks for the comment
@@HM_RELOADED That's unfortunate if it's a dud. I watched all 3 of your freezer videos and didn't notice you turn the unit on without the cables plugged into the unit and then press the boost button, figured I'd mention it.
@freakerss in the videos I attached the cables to the battery, and the GT4000 still was able to preheat after about 15 to 20 minutes, that's hooked up. I said we have also tested the GT4000 off camera when the GT4000 was Not hooked up, and we had the exact same results. So we are assuming we have a defective unit, but when we get the new one we are going to extensively test that one as well, hooked up or Not hooked up. When you say the GT4000 can't be hooked up in order for the preheat technology to work, my other videos show the GT4000 hooked up and the preheat technology was able to work after around 15-20 minutes. And the kicker is, after I tried the GT4000 when it was hooked up and the preheat never worked, I put the GT4000 to the side of the hood as my video shows throughout the video, and the snowflake never disappeared (GT4000 was Not hooked up) and it still never activates the preheat, until around the end of the video. Also, in the manual it doesn't say the GT4000 has to be unhooked or hooked up for the pre heat technology to activate. It just says when you're using the GT4000 wait 100 seconds and use the unit in frigid weather, or after 100 seconds you could push Boost and try to jump start. So the videos online and the actual manual are a wee bit confusing at times
@@HM_RELOADED I understand, thanks for explaining. I've noticed a lot of Chinese to English manuals often have numerous errors throughout them and can be contradictory or misleading.
I believe the 100s "auto-preheat" function is simply due to the current flowing through the unit into the battery, generating heat as electricity does when it flows like this.
From my experience the manually enabled pre-heat, as I explained in the previous comments, turns on the pre-heat symbol and displays the temperature, uses wayyy less power, since you are not discharging the unit to a battery and works much faster.
Again you may have a dud, but my unit does the same thing as yours, unless I manually enable the pre-heat mode.
I just re read the Gooloo GT4000 manual and it specifically says the Gooloo GT4000 should be hooked up to the battery for 100 seconds in order for the preheat technology to activate, or if the unit is Not hooked up to a battery just wait 100 seconds, then push the Boost button, then hook it up. So, the GT4000 preheat technology should work hooked up to a battery or not hooked up to a battery. But as another test I am going to throw the Gooloo GT4000 back in the freezer for a while, then after it comes out, I will Not hook it up to a battery, I will only wait the 100 seconds and push the Boost, just what the manual says. Let's see if the Gooloo GT4000 preheat technology activates faster than if it's hooked up to a battery, or if I have the same issue. I will let you know the outcome. You would think if the Gooloo GT4000 is hooked up to a battery or not, the pre heat technology should activate the same time, but we will find out.
most jumpers work down to 4F so this test is kinda pointless. -40F would have been more interesting.
Thats the whole point of the video. Just because a product advertises that it will work in -4 degrees, doesn't mean it will work. That's why I do these videos, because many jump starting companies false advertise. I test these jump starters to see if their products will actually work in frigid weather, and some of these jump starters do Not work properly in -4 degree weather, even though they advertise as such. So the video has an important point.
Thanks for the comment
Yesper Armor with pre heat worked for me in -50 degree celcius. I was able to jumpstart 2 cars before charging it and proceeded to the 3rd car.
@@justinlopez5895 Sounds like the Yesper Armor is a great unit. We will be reviewing it in the near future. Thanks for the comment
What is the watt hour rating of this jump starter. I cannot find that info on amazon or Lokithor website for any of this brands Lifeo4 jump starters.
According to the specs on their web page the Lokithor J401X has a WH of 74. I will double check when I get home and look on the actual J401X model and see what is says. But the J401X is a great unit as our videos show. I appreciate the comment. I will double check the WH, but it looks like it's 74WH. It was actually not easy finding the WH on their website, but after a few minutes I found it.
Gooloo is not for Canada. in winter we experience -45 digree Celsius in winter
Their new GT4000 is perfect for Canadian winters. It has an automatic preheat function if the booster is too cold. I live in Alberta and plan to keep this thing in my car year round…. and I park outdoors year round.
@@beri232 i saw few reviews it takes forever to activate pre heat technology Lokithor just activated in few seconds and Goolo takes almost 7 to 8 minutes. Which is not good when there -40 cel outside.
@deargill6137 some people say I may have a defective unit. So I am in the process of purchasing another Gooloo GT4000 to see for sure if my other unit is defective or not. Keep you posted
@@HM_RELOADED waiting for that Review. Lets see if it can beat Lokithor i have planning to buy one then will decide after review. Kindly do extreme cold test
@@Mr-Faraz92 you got it
Thanks for testing these units, very useful. Try to warranty out the Gooloo and test another unit.
Will do. Thanks for the comment. Have a great day
Of course is a northstar it’s 108 in Houston
That is way too hot for anyone...lol
Do you have a video where you test these jump starters when they were not put in the freezer ?
We have many videos testing these products, check out our channel. Thanks
There are tons of videos testing this charger without using the preheat function. Try looking!
@beri232 we actually made many Gooloo videos testing only its functionality, not testing pre heat technology. The point of this video was to see which units will work in frigid weather. Try looking. Lol
@@HM_RELOADED hey dumb-dumb…. The comment you replied to above was intended for @dallase1 ….. “try looking!”🙄
Wich is better ?
I absolutely love both the Gooloo GT4000 & Lokithor J401X, but if I must choose one, I would def choose the Lokithor J401X. Both units have mega power, both have preheat technology, both have nice LCD screens, both have multi-functional torch lights, both have portable power banks, both have boost functions, both are pricey, but I think the Lokithor J401X is heavy duty with very nice clamps, made just a bit better. Keep in mind that the Gooloo GT4000 has 4000A peak with 100-watt fast charge. The Lokithor has 2500A peak and 100-watt two-way fast charging. So, it's all a matter of personal preference. Both units
@@HM_RELOADED thank you very much ;) I want buy the lokithor 3250 but haven't on Amazon Europe .. so I buy the j401x a few seconds ago ;) ( I think a good price because 124 euro) after a gb70 Wich I really appreciate for 2 years and he's indestructible .I buy the successor gb150 and is a catastrophe.. is really bad ..
@@adsss2331 Great choice, let me know how you like it
You never activated the heating feature on the Gooloo!
Yes we did, over and over, on and off camera. We have numerous videos out about the preheat technology. If you read the manual it says to wait 100 seconds before the preheat technology activates, or push the Boost button and the preheat technology will activate. How many times do we have to push the Boost button to activate preheat technology. If you watched our other GT4000 preheat technology videos you will know that we push the Boost button a million times and we wait and wait like the manual says. The only other reason that it doesn't work is because its a defective unit. We have had a few other people say their Gooloo GT4000 does the exact same thing and the preheat technology never activates. So I'm assuming their are a few defective units out there, like all products. Thanks for the comment
P r o m o s m 😭
No offense but did you read the instructions? You have to hold both buttons down to force it into preheat. Ive did this test multiple times and have never had an issue. The Gooloo GT4000 is a fantastic machine. Its my opinion you are giving the jumper a bad name by not using it properly.
Yes, we read the instructions in the manual to a tee. And you are NOT supposed to hold down both buttons to force pre heat technology according to my manual and other Gooloo GT4000 owner manuals. My manual clearly says to either wait 100 seconds after the cables are hooked up to a battery, or if the unit is not hooked up to a battery to push the Boost button to put the unit in pre heat technology. If you kindly send us an email address, i will take a screenshot of the actual instructions for you so you can clearly understand what the manual really says. And if you have watched other videos, you would know that we always give Gooloo high marks. We have countless videos, so we are very aware how to use the Gooloo GT4000. So before making comments, you should really read the manual yourself before passing judgement, because no where in my manual and other Gooloo GT4000 manuals does it say to push both buttons to activate pre heat technology mode. I would love for you to send me a screen shot of your Gooloo GT4000 manual saying you must push the power button and the flashlight button (the only 2 buttons) at the same time to activate pre heat technology. I will be waiting for your screen shot. Also, we have been told by other people that their Gooloo GT4000 has the same issue as ours. So either we have defective units, or some units work, and some do not. Thanks for the comment
It is of minimal relationship to reality to show me a demonstration of "cold" jump starters starting a car in warm weather. Please stop and think for a moment of where on the planet I would encounter my starter being at freezing or lower temperature and my vehicle to be jumped is in warm ambient temperature. Unless I can get travel at light speed those two points are likely very, very far apart. The only realistic "cold" test for these units is for the starters and the vehicles to be jumped in similar cold circumstances. For example the temperature outside is 15 degrees F and both the vehicle and the starter have been sitting in that low temperature for overnight etc. That would give me an indication of how well one unit or the other starts the vehicle. The demonstration you did basically only showed the starter unit itself running through it's pre-heat mode. Fine but it has no conclusive demonstration of starting a cold car.
It is also not advisable to keep jamming the buttons off and on in short succession with these sorts of units. They have circuitry that runs them through various checks and will have built in time delays before proceeding to their next step. Many times by going on/off, on'/off, in close succession you're interrupting the unit and many devices will view this as a potential fault and then go to a "safe mode" of inactivity or shutdown for self protection. An impatient user might see that as "needing to push the button again" but it is not. If a shutdown or protection mode happens with many of these devices there will be a "wait" period of time usually called out in a manual. If not contact support. Keep it in mind for future testing of devices with circuit boards and "features".
Lastly I would point out to you that although these devices typically have a "boost" mode that is not to be misunderstood as it's "normal" use mode. If it was it would just be the default way it functioned. When you are in "boost" you are bypassing some of the other circuitry in the unit that is there for a purpose. Most of these units are designed for "normal" function to be with a vehicle battery that has a certain percentage of it's power. The Gooloo manual for the GT4000/4000S clearly says 20%. That doesn't mean "Boost" should never be used it simply means that these units are not designed for going around and jumping dead battery after dead battery day after day winter after winter. Use your tools within their operating parameters. For an occasional dead battery boost/start it's not a problem but not all the time.
It seems you missed the whole point of the video. These portable jump starters are advertised as fully operational in down to -40 F. Obviously, most places on Earth do not get down to -40f. That's where our freezer test comes in. We want to make sure these portable jump starters that are advertised to work in frigid temperatures. That's the whole reason we did this video, to see which jump starters will work and which won't. Because you may live in warm temperatures, but the rest of the World may live in frigid temperatures, and that's where our test comes in. So before making comments, please think, before you start typing and ridiculing a channel that is here to help people save money and not get ripped off.
Thanks for the comment
@@HM_RELOADED Apparently you didn't see one of the videos on YT where someone had both the jump packs and the cold cars and basically none of them were very effective because in boost mode most of these lower level packs only provide boost mode for a very brief matter of a few seconds once you start cranking. This is done so you don't overheat and burn up the unit. But better made units can allow a longer time and a unit like the Topdon V4500 Plus will allow you to crank for 3 minutes straight as long as you are cranking and not doing an on/off with the key. The better units sense load in boost mode and as long as they "see" load they will crank for the designed period of time. I do not live in a warm climate as you suggest and if I did it would be unlikely that my jump starter would be anything other than ambient. The pricing for the lower level units and the quality of the manuals is a tip-off as to what to expect in other than fairly easy "warm climate" scenarios. While the Topdon is a bit over $200 it is a much more robust unit and more featured with respect to things like diagnostic capability of the vehicle battery etc. Some like the Goodall are horribly expensive for what they are. Some like the Yesper Armor Monster while claiming to be of higher output do only allow short term crank of like 3 seconds in boost mode before they back off. Additionally the manual is pitiful in most of the areas and is basically a one page item sort of thing. There is a giant capacity unit out there claiming to have 10,000 amps and the metal case seems cool but way too many people are talking on Amazon about the cables being undersized and getting super hot. There currently is no standard or regulation about power output claims and so anybody can claim anything at this point. But back to your demonstration it seems that you wanted to show how these lower tier packs recover from the cold using the "preheat" capability. Fine but you used the ability to start the car as your indication of how well they recovered. That is in the realm of what I'm talking about with using a cold vehicle. Like I said about the other video where they didn't do well in the cold regardless of the preheat and someone looking at your video might think that based on your demonstration one or the other of these units you tested would be a good cold weather performer when in reality none of the lower tier stuff has great success in those conditions unless the vehicle battery(s) only need a little help rather than a lot of help. They have the most positive result with a vehicle that has an engine in decent condition but struggle because of the cranking time limitation when they are faced with an engine with stiff oil and a somewhat degraded compression, fuel/air delivery and spark condition. A suggestion for future "tests/demonstrations" with electronic products would be to do a "rehearsal" or "bench test" video to make sure a unit actually works and you could make a video of it before your "show-time" video. That way if a unit passes once but then fails in your subsequent "test/filming" you could just cut that out and edit in the one that did work and not in your narration that the unit was OK initially and then failed subsequently. That way your main video you put up doesn't take up time with fussing with the failed unit and trying to get it to work etc. Accomplishes the same thing to just describe that the failure took place and show the successful first run. You did well to persevere with Gooloo and obtain confirmation that the unit was faulty.
@2muchtoomanytimes Apparently, you did not understand my explanation in reference to your first comment. And we are very capable of using and explaining how jump starters operate because we have been doing this a long time. We do not base our knowledge on what a few other UA-cam videos show in their videos, as you pointed out. We explain and show people how to use jump starters from our everyday experience, paired with factual information. We are not sure why you have such an issue with a reputable UA-cam channel showing portable jump starters that have been in the freezer to show most of them work in sub zero temps. And keep in mind, just because it was hot outside when the test was done doesn't mean anything, the whole point was to show the actual Frozen jump starter will perform when needed. Now, in reality, when it's below zero temperature wise outside, most of the units I test will work in frigid weather, as we have seen from the freezer test. By us showing that most of these portable jump starters are able to jump start in frigid temps, will show the average person watching our videos, that the portable jump starters I'm showing and testing, are worth buying. That's the whole point of doing the freezer test. Let me ask you a sensible question. Would you purchase one of the jump starters in our video knowing it's able to jump start a car battery in frigid temps? You are aware that it gets below zero temperature in many, many parts of the World, knowing a portable jump starter will work in frigid temps is the whole point of our videos. Remember, not everyone will have the same experiences using the same products, our job is to review and test from our experiences on our videos. What everyone else does with the same products is their experiences.
Please understand we appreciate your comment, but we are trying to help people, bottom line. Keep in mind, out of many, many, many viewers and commenter s on this video, you are the Only person who is making an issue of our freezer video. If you don't like the content we provide, please go elsewhere and refrain from negative comments. There is no place for it. Have a great day
@@HM_RELOADED You did not show that it will jump start a battery in "frigid" temperatures. That's part of the point. You showed that the unit was coming from frigid, warmed itself to an extent and then jumped a warm car/battery situation. The battery and car were never frigid. But whatever and I look forward to your next test of frozen ink pens brought out from the freezer into the Texas summer sun to scribble on paper sitting in the sun and then having you tell everybody about how well these pens will write beautifully in 0 degree Fahrenheit weather. Someone tries to help you do better and you can't take constructive criticism or suggestion about how to make your testing and video presentation better. Keep bumbling along and have a good day.
@@2muchtoomanytimes Again, you totally missed the whole point of the video. You weren't trying to help someone when you make negative comments. Your comments were not constructive critism as you say, you were downright rude and belittling on certain comments. If you didn't come at us the way you did in the comments, we would have been much nicer, just trying to show there is no need for certain comments. The jump starter is frozen, that's what we are talking about. The jump starter is experiencing frigid temps, which in turn would describe how cold it could be outside temp wise for the jump starter to work. The frigid temps are describing the jump starter being in the freezer, not outside weather. This test was an extreme test, meaning if the frozen jump starter is able to jump start a dead battery, it's a good jump starter. Obviously, I couldn't do this test when it's hot outside, so we had to do the next best thing and simulate a very cold day, that's where putting the jump starter in the freezer comes in. See what I mean? My video had nothing to do with outside weather temps since it was hot that day. I had to simulate a freezing cold day to see if these portable jump starters would work or not. I will go play with frozen pens. Like they say, there's always one in every group.
Thanks for the comment and the support.
Если бы ты не лез своими кривыми руками к штатным, заводскиму кабелю он бы работал как положено! Ты нарушил сопротивление !Признайся честно! нахера ты кабеля резанул ? удлинить захотел😂😂😂
Let me ask you a question: Are you out of your mind with that dumb comment. First of all, the Gooloo GT4000 is supposed to activate the preheat technology with or Without the cables attached, as the Manual says. There was no resistance broken as you say. If you watch other videos on the Gooloo GT4000 and the preheat technology, there are a few videos demonstrating the preheat technology activating With NO cables attached, so obviously the cables arent the issue then. Also we have and a few Subs contact me and tell me they have the same exact problem with their Gooloo GT4000 not activating the preheat technolgy. And guess what, those other people didnt mess around with their cables. So obviously your theory doesnt hold water. So obviously us cutting the wire cables didnt have any affect what so ever. We are thinking we have a defective unit like the other 2 people that contacted me to share their experience. And if you paid attention to the other videos, we extended the cables for a reason, obviously you didnt see the point in doing that. Please take a minute and read the Manual with your crooked hands. If you would have commented nicely without negativity, i would have been much nicer, but since you commented something negative, you get a negative response back. Please refrain from negative comments in the future. Thanks for the ignorance.
