Frequently Asked Questions
Find answers to common questions about our products and services
These are USB-C rechargeable AAA lithium batteries. Unlike regular disposable AAA batteries, you can recharge them again and again using a USB-C cable — no separate battery charger needed. They save money and reduce waste compared to throwaway batteries.
These batteries have high capacity (around 500 mAh–750 mAh) and can be recharged up to about 1200 cycles. That means each battery can be used hundreds of times before it needs replacing — which is much more than standard rechargeable NiMH batteries.
No extra charger is required. Each battery has a built-in USB-C port, so you simply plug in a USB-C cable (included). You can plug it into a USB power adapter, power bank, laptop — anywhere with a USB-C output.
Yes — they work everywhere AAA batteries are normally used:
✔ remote controls
✔ wireless keyboards and mice
✔ toys
✔ flashlights
✔ cameras
✔ game controllers
Just insert them like regular AAA batteries.
Yes. These batteries typically have built-in safety protections that prevent overheating, overcharging, and short circuits. Still, it’s best practice to unplug them after a full charge and avoid charging near water or very hot areas.
