- Do these work in any AA device?
- They fit standard AA slots and output 1.5V, so most devices accept them. Very high-drain gear will drain them quickly because of the 1700 mAh capacity.
- How do they compare with NiMH rechargeables?
- NiMH cells offer more capacity and lower running cost, but need a separate charger and output 1.2V. Paleblue trades capacity for built-in USB-C charging and a steady 1.5V.
- How long does a charge last?
- Expect shorter runtime than a 2000 mAh or higher NiMH cell. In low-drain items like remotes and clocks they last a long time; in toys and motors they drain fast.
- What do I need to charge them?
- Any USB-C cable and a USB power source such as a phone charger, laptop or power bank. No dedicated charger is required.
- Are AAA versions available?
- Yes, Paleblue makes the same USB-C rechargeable design in AAA as well as AA.
- Can I leave them plugged in?
- The cells stop charging when full, so leaving them connected to a powered cable is fine.
