I got a few of these. They are really nice, but big. However, they are not 40k... They are around 20k with my tests

how did you test? and I guess some energy is lost but that much it is too much, on another brand that I checked recently they said around %30 less but %50 wow.

isn't then this false advertising or something of that kind?

One of the reviews wrote that there are two revisions and idk the woot one listed on Amazon is $99.99 idk why, but I guess they were saying the newer one is better. and hopefully the one being sold by woot on their site is the same that sold on amazon by them.

A review on Amazon confirms you're right, they posted a photo of its true capacity. Thanks.

That's pretty much 100% of listings from Chinese sellers. Why bother, you can always delist under different "brand"

Did you consider efficiency?

I have a few 5,000mAh Anker that I got to latch onto my Retroid Pocket 4 Pro and tested with a 5,000mAh phone I get around 66% which is normal due to voltage conversion to USB standards.

Yes you can.

A 27,000mAh at 2v is legal. A 40,000mAh at 1v is legal. A 100,000mAh at 0.1v is legal.

As long as the factors is below 100Wh, you are good.

What is not legal is going above 100Wh.
