GP ReCyko 4-Port USB Charger B441 incl. 4x AAA 850mAh Batteries GPRCKCHB441U007

Unlike single-bay chargers that force you to juggle batteries, the GP ReCyko B441 charges up to four AAA or AA NiMH cells at once from any standard USB-A port. It arrives ready to use with four pre-charged ReCyko AAA 850 mAh batteries, so you can power remotes, toys, or wireless keyboards immediately.

Highlights

• 4 charging slots for AA or AAA NiMH rechargeable batteries
• Powered by a standard USB-A port (5V DC, 1A) — works with PCs, power banks, or USB wall adapters
• Includes 4x GP ReCyko AAA 850 mAh batteries, pre-charged and ready to use
• Charges in pairs: 2 independent channels with LED indicators
• Timer cut-off and reverse polarity protection for safe overnight charging

In daily use

Insert two or four batteries and the B441 starts charging automatically. A red LED per channel shows progress and switches off when the pair is fully charged. With 200 mA output for AA and 100 mA for AAA, a set of four 850 mAh AAA cells reaches full capacity in about 8 hours. The compact white housing sits neatly on a desk or travels easily in a bag.
