The use-case for batteries like this is very specific. The buck converters to drop lithium's natural 3.7V to 1.5V will consume energy while not in use, worse than old school, non-LSD NiMH batteries. That really only makes them useful in high-drain devices in constant use, especially ones that are also voltage-sensitive (like some that read 1.2V NiMH as "dead").

I think these are popular for battery-operated Blink cameras because they meet that criteria (including the voltage sensitivity), though Blink says not to use rechargeables.

Generally speaking, a high-quality NiMH like Eneloop is going to be a more cost-effective purchase. You don't need these in your TV remote.

love these- picked them up in feb for my blink cams which want 1.5V not, 1.3V AA so they always show low battery until I put these in...far more predictable now.

Community Reviews

These USB C lithium AA rechargeables stand out for devices that need a steady 1.5 volt supply, especially Blink cameras and other voltage sensitive gear. The constant voltage can make low battery behavior more predictable and avoid the false low warnings common with NiMH cells. They also get praise for strong output in some high drain uses. The main knocks are misleading capacity claims, slower charging than hoped, and uncertain longevity, with some reports of sudden cutoff and weak USB output. A niche pick for the right device.

I remember when Tenavolts was one of the first ones to go to market for these type of batteries. Lots of early deals on their batteries. They don't seem to be around anymore based on no activity on their website for awhile.

is there a coupon that works for the 12 pack? is a bit more cheaper after breaking down to pack of 4.

What's the longevity of these? Could use 10-12 of these around the house, but heard rechargeable batteries go to poop after 6-8 months.

But that was also a year or two ago. Haven't really looked into it since. 😅
Cheap, poorly taken care of NiMh can die a quick death. Good NiMh, taken 'reasonable' care of can last a decade+. I have some over 15 years old and still being used.

These would be a cheap way to find out about this chemistry. Do some homework.
Emphasis on CHEAP. Since it's a new chemistry no one REALLY knows how long they will last.
I've got some Tenavolt Li that are 4+ years old that are still doing fine. But, they aren't the cheap ones.
I do have some HW Li, but NOT the USB version. Only had them maybe 6 months, so don't know longevity.
False capacity claims are a hallmark of this kind of battery. 70-80% of claimed capacity seems to be in the usual ballpark.
They do NOT have the claimed capacity. > 1768 to 2010 mAh
There is a trade-off of less capacity while USB charging vs proprietary charger.
This capacity review is worth checking out.

The use of mwh instead of typical mah is kind of misleading.

As another person mentioned further down these are 2500mah equivalents so the 3600 makes it seem better than they are.

Edited: math was wrong and corrected by another user. Thanks for the info.
math aside (which this battery is actually better than eneloop pro or the powererx by quite a margin, i guess you were also mislead by the previous deals by the person who had no idea what his/she was talking about and get a bunch of upvote for the completely wrong math), the use of WH for power storage is, and should be the standard.

AH isn't really a unit of energy nor work. just FYI. AH relation to Energy is like saying because something is taller than some other thing so one must wight more than another. Macbook air battery is about 4000 mAH, you really think two eneloop beats a macbook air battery in size?

Not trying to threadjack, just wanted to comment to earn another entry for today's SD giveaway, lol.

But, I grabbed something similar off of Amazon's Haul during BF. Looks like they're currently $6 for a 4-pack, claiming only 1200mAh a piece.
https://www.amazon.com/TOPUSSE-Re...0D9H1VLBH/

Been using them for 5 months in my Quest 3 VR controllers. When I'm alerted the batteries are low, I've got only about 10 minutes left of usage! I'm cycling these about 4x as quickly as disposable Alkaline AA's, but a little less waste using rechargeables.

Be nice to know the actual capacity. No reviews to that end on Amazon.

This is misleading marketing.
Maybe a bit, but then I don't believe the EPA mileage nonsense on new cars, either. And EV manufacturers lie about range the way people lie about their age and weight on dating apps.

I think I fixed the link. I pulled it from another discussion on the same battery. The link works THERE, but not HERE after cut and paste. I refreshed it. Seems to work, at least for me anyway. The useful part is the tested finding of [1768 to 2010 mAh].

Does anyone know if these can be used as power banks? ie, does the usb-c work in reverse and allow you to charge usb-c devices from this?
