wowpower Rechargeable Lithium AA Batteries with USB-C Charging Cable, 8 Pack 1.5V 2100mAh (3150mWh) Li-ion Double A Size Battery for Blink Outdoor Camera, Xbox, Flashlights, Toys

So far these AA lithium rechargeable batteries have worked just fine. I say so far because I can't speak about their longevity just yet, but so far my experience has been positive. I am using these in a high powered LED flashlight without issue. They last a long time and recharge quickly. I like that they have the charging ports built in so you don't need a separate charger, and they come with a four place charging cord so you can charge them all at once. My only complaint is that it's a bit hard to see the charging light, especially in a bright room. It's inside the port and isn't very visible, but I'll get used to it. I like these so far and I will update my review if they don't hold up.

These AA rechargeable batteries have little type C ports at the top of them for charging. They do not charge in regular chargers. I put them in a regular charger and the indicator lights did not come on. They use a usb cable that has 4 type C heads and is very short. I disconnected one and hooked up the top of my hands free breast pump and it showed it was charging, so you can use thr cable for other items. The batteries came in a plastic box that snaps shut, which can be used for storing them when not in use.

I’ve tried rechargeable AA batteries that use wall units to juice up and I’ve come away disappointed with the heat, the functionality, the difficulty of using them, etc. That’s why I’m much more impressed with AA batteries that recharge via USB-C. You just plug them in and that’s all. There’s no extra wall unit to haul around with you – if it works properly to begin with. These don’t provide an exceptionally high amount of power (my EBL batteries are 2,800mAh and my Eneloop are 2,000 mAh), but these do give more juice than other USB-charging AAs I have that are 1733 mAh. Of all the rechargeables I’ve tested, these have the lowest number of advertised recharge cycles (1,000+) compared to 1,200 or 2,100 with other batteries. So either they’re on the low-end of recharge cycles, or the company is just being modest and we’ll get better results. We’ll see; 1,000 cycles is a long time anyway. These look good and have worked well for me so far. I like the hard-plastic battery carry case, but if you latch it shut it’s difficult to pry open without a sharp edge.

I love batteries that have charging ports built-in, as they're more convenient than ones that require a separate charging cradle. You can use any old USB-C cable to charge these batteries, but they come with a cool multi-headed one. These batteries are working great in my wall clocks so far.

I picked these up to use with a portable fuel pump that uses four AAs. It won’t get used often, so I wanted batteries that would hold a charge long-term, and these lithiums were just the ticket. They are simple to recharge, and worked with even the lousiest USB power adapter I could dig up. Time will tell how many recharges they’ll take and total life.

These batteries easily charged to capacity. They came in a nice hard plastic case with a 4 way USB-C charging cable. They look and feel like great quality materials. I am very pleased with them. I would definitely recommend these batteries.

I like to use rechargeable whenever I can but certain devices like my electronic door lock requires a full 1.5v or it just won’t work. So far this set works fine in my lock. This set comes with a case that holds 8 cells so there’s always some place to store the 4-in 1 charger to recharge these batteries. One issue I’ve had is that the charge indicator light is small and dim so it’s hard to see if the indicator is on or off. Not a huge deal but there are others that have a much more apparent indicator.

The Wowpower Rechargeable Lithium AA Cell Batteries are a solid solution for powering various devices like Xbox controllers and toys. These 1.5V, 2100mAh batteries come in a convenient 4-pack, offering long-lasting performance. What sets these batteries apart is the USB-C charging capability, which makes recharging quick and easy. The inclusion of a USB-C charging cable is a thoughtful addition, ensuring you have everything you need. The batteries hold a strong charge and are ideal for high-drain devices, reducing the need for frequent replacements. Overall, this set offers convenience, durability, and value.
