As an electrical engineering student who is interested in pursuing power electronics. This channel is awesome and I really appreciate the all the data that you provide. I was amazed when I learned that the 65 watt class of USB-C power adapters do not have active PFC, when 9 Watt couple dollar LEDs bulbs have it. That is ridiculous. Also I’m very jealous of your equipment, sweet stuff.
Nice! Great to hear someone interested in the field. It is certainly a growing field with electric cars, heat pumps, and more powerful gadgets always being created. If you want to be jealous of gear watch The Signal Path lab tour... but yeah, I have a budget and each year expand my collection. Anyway, share with the other students!
Good work as always. I think Dewalts concept is quite good, charger that can be powered from power tools batteries. If someone would release something like that but it can take batteries from top 3 or 6 power tools manufacturers and it's quite efficient (and power quality is good) I'm in.
In Germany they sell the USB-C charger with 100 W power supply and it does charge with up to 100 W from USB-C. The nice thing you can already charge the battery with only 5 V on USB-C, of course probably pretty inefficient but with it you can charge batteries super slow in car or office if that works for you. Perfect match for me. I hope competitors will also release USB-C chargers for their 18 V batteries.
Excellent video as usual, i do recommend you also try out the mophie powerstation pro xl (200us one) considering its 40% off as of writing this message.
I charged a battery with a small solar panel with this, then used the battery to charge my other stuff at night. The fact that it will discharge the batter if left in is, IMO, a major oversight.
Yeah, I never did test this as a battery bank. So, the port stays on is a good thing for certain applications but yeah also means flat battery when you need it.
I made my own "power bank" solution for 18V Ryobi tool batteries. I bought a for parts/not working Ryobi battery charger to use as a battery holder (or there are purpose-made adapters, search eBay for: ryobi battery holder diy) and soldered a car cigarette lighter socket on the output of the terminals. Then simply plugged in a car USB-C charger, as most(?) of them accept 12-24V input. EDIT: I should mention, it's my understanding that Ryobi batteries have built-in low voltage protection, whereas some other brands handle the low-voltage cut-off on the tool side.
Nice! I think that is awesome. I like hearing about projects like that. Yeah, the battery pack has to have internal management for a lot of these applications. And yes, most car power adapters accept 24V, not all though.
I bought the Battery-hat kit as soon as it was available because I have dewalt batteries and it allowed me to use my laptop in the field almost indefinitely. Interesting side note, in the UK where I am the kit comes with a 100W USB-C PD adapter instead of the 65W. Otherwise it seems to be identical, same design/shape/manufacturer, just bigger of course. The adapter with the kit isn't ruggedized as it's meant to live "at home" I believe. On a jobsite you'd charge the batteries with a regular dewalt charger instead.
That's interesting. I want to try the 100W charger now. Yeah, the 65W is the same, it's home grade versus the rest of it being tool grade. I use it as a random power bank once in a while. I don't even have any official dewalt batteries, ha.
@@AllThingsOnePlace Another interesting point is my 100W one has 5A written on it, so it can charge DeWalt batteries at the full 20v 5A PD rate, so does not have the 3.25A limit this videos model has
I suck at (understanding) electronics lol. I purchased this kit but also purchased an Anker 100w wall charger. If I'm understanding correctly though, that wall charger will NOT charge DeWalt batteries any faster. Is that accurate? Is there any point in using a 100w wall charger with this kit?
That's a good question. With a 100W wall charger this kit will charge battery packs faster, but only a little faster at 70 watts versus 65W with the supplied charger.
Thank you again for your work , sorry been busy, also aren’t there a 100 watt out put variant ? Will you be testing that out? I wish power tool batteries could jump to the 240 watt output since some of those batteries can output such . Will you be testing the anker 30 watt gan slim charger? Also the 65 watt sankton charger ?
I didn't see a 100 watt wall charger from DeWalt. Yeah, the batteries can supply plenty of power. I mostly like this one lets both ports operate at the same time. I might have the slim charger here already, and I have a whole bunch of the 65W slim chargers, I expect all of them to be worse since they have to sacrifice space for quality... I need to do an inventory but as you said busy is a problem. There's 80 chargers here untested.
I use the dewalt charger in my truck. It keeps me from having to bring batteries in every night to charge. I use a Ugreen 12v adapter that will apparently output 100w. Which is pretty necessary as my 9ah skill saw battery is 180wh and I can kill one before lunch if I really try. Even at 100w it still almost 2 hours to charge. The only dewalt 12v adapter I could find was 18w. That would simply take too long. Also, it's hard to find a 12v adapter that actually outputs 100w at 12v. Some say they do, but they only actually do when plugged into a 24v outlet. The ugreen must have a pretty solid boost converter to be able to do this. One other note, I used the dewalt battery adapter to charge my laptop. With a 2ah battery, you only get to use about 2/3 of the battery before it can't charge anymore. Presumably because my thinkpad won't charge with less than 20v. I am yet to see if using a 60v flexvolt battery would fix this. I also wish dewalt would sell the battery adapter by itself. And that they would produce some good 100w+ wall adapters and 12v adapters to go with it. And, the addition of a boost converter circuit for the output would be magical. You've inspired me to get my bench supply and meter out for a thorough efficiency test. I'll put it on my channel, whenever I get around to it.
Yeah, I did a few car chargers and found that very problem with some of them, they needed 24V to do the full power level. I also agree I wish the battery adapter was sold on it's own or in a kit with a car charger. They're charging too much for the AC power adapter that comes with it, and it isn't that good. Also, nice! Share a link when you do!
any update on modifying it for higher voltage output? I have similar plans but all the knock off brands battery to usb items seem to all lack proper bms
Hey cheers from Mexico 🎉 have you consider making your own brand of power adapters? I love that you test the capabilities of some powers adapters I own and I am always looking for new good quality adapters. I know it’s a very expensive project (like Linus with his back pack) but you seem like the guy just for the job.
Hello! Yeah, there have been a few others talking about me making a power adapter. I know I have the data on how to make the best one in each category. I do have a bunch of development kits too so the process is lightly started already. I should do some polls on what people want...
Pleased do a review/comparison between xiaomi and baseus 100w 12v dc car chargers. There doesn't seem to be any other legit or semi-legit brands making those. Baseus also makes a 160w car charger but that requires car with 180w socket, instead of the typical 100-120w.
Yeah, there is also a DeWalt one. The 160W Baseus one requires 24V on the input to do the full power. I've had that here for months haven't tested it yet though.
That battery adapter would hold its own versus the anker 737 powerbank on an airplane and a hell of a lot cheaper if you use the same cells you are in the video.
The high-capacity DeWalt batteries come with a transportation-mode cap which breaks the circuits and partitions the cells into multiple batteries, each under 100 Wh. Supposedly, this makes them legal to bring on airplanes, although you couldn't use it on the airplane. I suspect multiple 100Wh power banks would be more practical for most road warriors, but it's an interesting concept.
i have the DCB094K USB charging kit. works great for me, The 65 watt usb C is ok. but could be better. wish it was 100 watt for faster charging. The battery level gauge is on most 20V and 60V batteries. it does charge from solar just fine even a smaller 5V one. It can power a 45 watt USB C laptop for many hours just fine. great power source for backpacking and camping .I have DeWalt 20V/60V tools and many batteries all ready . just great add on to growing 20V system. I use 12V to USB C Anker for charging in the car or work truck. great way to charge going to job cite.
Yeah, I agree. The system of battery packs and expandability is great. I really like the USB C battery option and the fact that yes, it charges from basically anything. I plan to do more on these at some point. I know a bunch of other companies are offering similar things now.
when I tested mine I was able to get my dewalt battery pack to charge at 98Watts but when I tried to charge a generic dewalt battery it would charge max 80 watts
Nice, quick and to the point. What do you know, A man who doesn't just want to hear himself talk.... A+ thank you.... 65w and 50w almosst never use either I use the 65w occasionally to plug on my laptop.. safe, please? XPS power brick is 60w iirc
Thanks! Yeah, for the most part OEM adapters are safe to use. The XPS brick if authentic I'm sure is globally safety marked, they generally are well made as well. I still need to test this battery USB adapter. I used it the other day for something.

Thanks for reviewing this! I've been hoping you would
No problem. Yeah, I was waiting for the battery kit.
Top notch quality review. Although I am not interested in wall adapters, very eager to see results of the charger. Thank you.
Yeah, I am waiting for it too, haha.

Yeah, the charger piece should just be a separate product. The power adapters themselves are not so great.
there are adapters that allow batteries from other manufactures to power dewalt products. So technically your request is already covered.
Look
At ego power station that takes 4 batteries
In Germany they sell the USB-C charger with 100 W power supply and it does charge with up to 100 W from USB-C.
