1300mWh divided by 1.5v = 866mAh.
I've tested a LOT of 1.5v AAA. Most are ~300-400mAh. The BEST, Tenavolt are ~675.
The worst, ALL of them with USB charging are 250-300. That USB port takes up precious room in a very little can.
I fully expect these to be pretty lame.
The HW AA I test WITHOUT a port were ~80% of claimed capacity.

Mine pretty much end up in remote controls. They work well, until they don't.

The point isn't to last longer, it's for devices that benefit from a higher voltage.

I ordered the AA for my blink camera that requires 1.5V. Using regular rechargeables gives a 'low battery' even at 100%.

These are lion cells like 14350 in AA size. They have a circuit to step down from 3.7v to 1.5 and there are a couple types, some maintain 1.5v until they exhaust their charge, and some that gradually decline like a regular battery. They'll last around 10 years as a general rule. As Harley48 mentioned the capacity is reduced both by the DC to DC transformer and the USB port. Some come with their own charger because they have to recharge through the transformer. This brand adds the USB which is a lot easier to use since you don't need a specific charger you just use a phone charger. My favored brand is Coast. They are an American brand and give you a lifetime warranty. This is good on 2 fronts. 1 they will be recalled if they have problems like fire where these Chinese brands aren't always. And if one fails it will be replaced for as long as you own them

That's interesting. I guess they output a steady 1.5v until the lithium cell hits 3.7v and then just chop the power.

Pardon my ignorance here. I have not heard of rechargeable lithium. Do these last a lot longer than regular rechargeables? Outside of the USB aspect - which does seem a little silly.

These things claiming 1300mWh smells like total baloney.

The same manufacturer had another deal on AA batteries recently. We learned that it is a reputable brand if nothing else.
It was also an interesting observation that they measure the capacity not in mAh but in mWh.

I have a bunch of TENERGY AAA NiMH that discharge at 750-800mAh consistently but yeah the USB circuitry eat into the total capacity.

JSIAXWXT seems to still work. Sometimes going through checkout again can help if Amazon is being stubborn.

I disagree. A recent thread from these guys had several people getting the wrong item (AAs) and then they changed the Amazon listing, so you couldn't get a replacement for the correct item.

We still have some tenergy batteries that we used on our kids toys 10-15 years ago that still hold a charge.

I had some of their AA that fried (probably my fault) and they refunded my order and gave me a pack of AA for free.

This way they get to put a number on the package that's 1.5 times the number on the packaging of competing products!
