The AC180 just needs calibration. Fully charge on AC, fully discharge in one go (using a heater like you did) then fully charge and power off (long press on the button). This sets the BMS to better know where full and zero are so you get a more accurate read on the display. You can do the same on all power banks. If you usually use up a lot of the capacity, not needed that often, but if you typically only use a small amount before recharging, doing this every now and again will help display accuracy. As you found the actual capacity isn’t affected, just the display readout. Also, larger inverters are inherently less efficient, so you would expect a 1800W inverter to be less efficient than a 1000W, but they are more flexible.
Thank you sooo much for this video because I thought it was just my unit! I have a few PS and the AC180 is the largest one I have and I noticed that it discharges faster than any other PS that I have. And I’m not talking about about using AC but DC. 😢
@@hertechprep It may just need a recalibration . Charge it 100% then unplug the charging cord and run it down to 0% using a resistive load like fan or small heater. Do this cycle two or three times. Then try using it normally. It will adjust the computer to what level is full end what is empty. This worked for me, and as directed by BLUETTI service department.
I have this model. One major disappointment is that the AC inverter itself consumes 20 watts per hour. This drastically reduces actual operating/ discharge time for low load items. Say you plug in a 20 watt TV , you would expect 50 hour runtime, but the AC inverter steals another 20 watts per hour, reducing runtime to 20 something hours.
If I understood the information I reviewed on BLUETTI'S website yesterday...then a KEY point you are missing with the AC180, is that currently that unit's Watt Hours rating is NOT expandable by connecting Expansion Batteries like the B230 or B300. Currently, those expansion batteries can only be used to recharge the AC180. In contrast, the AC70 CAN accept the expansion batteries...B80, B230, or B300 and CAN expand its Watt Hours capability. Thus, I ordered the AC70 with an added B80 expansion battery, which increased its capacity to 1000-Watts for 1,574-Watt Hours.
I'm pretty sure I said that, but if not it was an oversight. I definitely said it in this one! ua-cam.com/video/sDKLRr-UZzc/v-deo.html - thanks for the important comment. You're right that it's a key point!
I think i know whats going on here. the AC 70 is able to supply a higher wattage by reducing output voltage. it's a sort of overboost feature that allows the powerpack to work with more devices. I think thats why it appears to have more energy. Try with a reduced load that does not cause the AC70 to drop its voltage.
My personal view is that it's the same wattage but delivered at higher current with reduced voltage. If the voltage was fixed and the higher current was demanded, the power station would trip - this is what happens on older power stations without this mode
thanks, very interesting review. I'm just about to buy one and I'm deciding which of these two options to buy. you have given very important information!

for me deal breaker was to have 2x usbc 100W, i bought ac70, thanks for compare them both
Yup, I think that multiple 100w usb-c is becoming table stakes...

I have both in United States love them both
It's like two different children. You love em both, despite their differences! 😂👍
I'm very interested in whether ac 180 can run 1000 watt microwave. AC70 cannot do this. AC70 can run 5 cup coffee pot nicely.

I was surprised, but by the end it was back to where I expected it should be. It just had a different route of getting there which was interesting!

@@paperback10 ok I will give it a try. I only did one run of this thinking it would reset and fix the problem
But it did not.

you gotta be a little more specific lol
And overall the unit uses 15wh just from being powered on.
Yes, I may do a video on this. A small parasitic power drain can have a big impact. Good point!
Hehe
Which unit are you saying does this? You just said I have this unit. He's reviewing 2, which one has those issues?
A very interesting information. You helpme a lot in my decision about which to buy. I think for me the AC70 is enough. Thanks!!
No problem Vic!! Please use my affiliate link if you buy - no extra charge for you 👍
The AC70P has the wireless charging on top of the unit
@@scottbenson8105 good to know thanks. Have you got one?
@@CampingSecretsUK no but I belong to a BLUETTI fb group and it is also water resistant and has more wattage
@@scottbenson8105 I'm testing the AC240 at the moment which is rather nice. Water resistant too 👍
I bought ac70 bc of price
The AC180 was on sale for the same price at the AC70 on amazon a few weeks ago.
Do not purchase.
Why?
@@CampingSecretsUK ecoflow fan girl .... i love bluetti and ecoflow i think ecoflow have a better phone app in my opinion.
Purchased! Love it.
@@kellyabercrombie9769which one did you purchase?
@@jazzycool2950 I bought the AC70. It’s doing great. We’ve already used it several times, once in a semi emergency.

AC70P contains Wireless Charging Pad
Mine doesn't!
Ac70p is a different model to the ac70

That feature -- "Power Lift" must be enabled in app
thanks, very interesting review. I'm just about to buy one and I'm deciding which of these two options to buy. you have given very important information!
No problem!
@@CampingSecretsUK still decided to purchase 180
