Description
The GP Recyko B423 is a four-slot USB battery charger supplied with four Recyko 2100mAh AA rechargeable cells (batteries). It charges 1 to 4 AA or AAA NiMH batteries at a time, so you can top up a mix of what you have to hand. Power comes in via a USB-C input, which means you can run it from a laptop, a wall adapter or a power bank without needing a dedicated mains lead.
We like this charger for its simple, practical design. An LED power indicator gives you a clear read on charge status, so you know when your cells are ready to use. Bad battery detection checks each cell before charging, adding a layer of safety if you drop in a battery that is past its best. The auto cut-off stops charging once the batteries are full, which helps prevent overcharging and looks after the life of your cells.
This is a dependable everyday option for anyone running rechargeable AA and AAA batteries at home or at work. The four included Recyko 2100 AA cells give you a set ready to go straight away, and you can charge different sizes at the same time. It suits camera flashes, remote controls, torches (flashlights), toys and other household kit that gets through disposable batteries quickly. Swapping to rechargeables cuts down on waste and, over time, saves money too.
