Rechargeable AAA Batteries USB C 1200 mWh Triple AAA Rechargeable Battery 1.5V AAA Lithium Batteries with 4-in-1 Charging Cable and LED Charge Indicator, 4-Pack

Good lasting battery they function good and good value for my money love that I don’t have to buy constantly batteries I just charge them and reuse. Very durable. Good size.would like them to be usb but I have to plug it but it’s good

A very handy item to have when you need batteries for a light. Saves a lot of money on buying replacements for dead batteries in things like mini-flashlights. The built in plug makes recharging easy. Also good for the environment as you throw away far fewer batteries.

My old wall station rechargeable NmH's died mid-trip. Suffered my phone light instead of 12$ for 4x disposable alkaline. Skimmed 10 other usb-c AAA’s reviews, most proving lackluster <400mAh results or fire hazards. Typical AAA's max out between 800-1200mAh at 1.2V so I was skeptical of a higher 1.5V battery's power claim (1200mWh/1.5V = 800mAh) while making room for built in usb-c convertors and at a cheaper price...0 to full charge took ~2.5hr (faster than my ~10hr NmH station but not 1hr as claimed). No overheating. Charging speed capped ~0.6W (5V*0.12A per battery) regardless of multi-split cable *OR* individual usb-c cable (great compared to other brands that required carrying the special split cable or an old usb-c-to-a cable). Batteries worked with a variety of usb-a (5V/1.5A) & 9W/20W usb-c plugs (still charged slow at 0.6W but gives you options).Average INPUT was ~1442 mWh. They'd need to be >80% efficient to reach 800mAh claim. Still an impressive charge.Real world test: batteries were just shy of my headlamp's max lumen runtime of 1:30hr. My old 800mAh NmH lasted 1:45hr. Worthy tradeoff considering 1.5V was noticeably brighter than the 1.2V. I recommend these for high use flashlights/toys. Especially activities you don't want to carry spares or a special charger.However, simple devices like TV remotes won't benefit from the higher 1.5V and are likely better off with traditional rechargeable NmH (better storage and low drain efficiency).

Great, they work, awkward to charge but not so bad, I am using these in the 3 remotes now to test them, before I buy 4 more packs of these. I only use these in low power usage devices like remote controls and some of my medical metabolic measuring devices, still that's 16 rechargeable lithium-ion batteries I need plus an extra 4 for charged standby so I don't have to wait on charge cycles when they run low. The FireTV remote seems bad to drain batteries fast, it must be the Alexa stuff and the constant comms they do with the TV / FireTV Box.

Bottom line, one was loose in my flashlight so I measured. Wikipedia says that an AAA battery should be 44.5mm long, these are not.The four batteries are 44.0, 44.2, 44.2 and 44.4 mm long. Besides all being slightly too short, the shortest of all three batteries does not make contact in a Black diamond flashlight. For something with a larger spring, this might not be an issue, but it's important to note that they do not meet specification for this battery type. In a device where multiple batteries were end to end, this shortage would be more likely to create an issue.In the photo you can see that it is clearly shorter than a name brand battery.

Easy to charge, good in remotes and computer mouse, saving me hassle and money. I love these and have started gifting them now.

Good look, seems like very convenience but not work. They are a bit too short so they only work for some remote.

These rechargeable batteries are super easy to use and a great eco-friendly alternative to disposable ones. They charge quickly, hold power well, and are perfect for everyday devices like remotes, cameras, and game controllers. Reliable and convenient!
