BC4A-500 USB Charger for Compatible Rechargeable AA/AAA Cells
Keep compatible rechargeable AA or AAA cells ready for toys and small devices. The BC4A-500 USB charger has four monitored charging bays. It is for users who can confirm their battery chemistry is explicitly approved for this charger.
- ✅ Prepare spare cells together — Four bays let you charge compatible cells in one place.
- ✅ See the charging status — LED indicators show charging and completion.
- ✅ Pack a compact charger — The small body fits into a travel charging kit.
- ✅ Connect through USB power — A micro-USB input uses a suitable external USB supply.
Match the battery chemistry before charging
Use the charger only with cells whose manufacturer explicitly permits recharging with this charging system. AA or AAA describes the size, not the chemistry: ordinary disposable alkaline cells must not be recharged.
Choose the charger variant for the four-bay unit. The USB Cable variant is an accessory-only option. The charger specification gives a 5V, 0.5A input and describes a 0.5 m USB-to-micro-USB cable; a mains adapter is not confirmed as included.
