GP U421

New, better, stronger

In 2016, GP Batteries introduced a new generation of battery chargers and this type of USB charger will bring you many benefits. These benefits include a smaller size, lower weight and greater compatibility with different forms of power.

These chargers are also equipped with state-of-the-art electronics, which control the charging process and offer lots of useful features. Forget about the old way of doing things because from now on, charging your electronics is going to be fast, easy and convenient.

GP U421 USB Battery Charger

The latest GP Battery charger offers many useful features. Because of recent developments in consumer electronics and the worldwide expansion of the USB platform, you will be able to charge almost anywhere, anytime .

The GPU U421 battery charger can be powered from your car's cigarette socket, from your laptop's USB connector, from a powerbank, or on a train or plane. The charger is both small and light-weight, so it will be easy to transport from one place to another.

A micro USB connection cable is included. For optimal operation of this charger, a 2A/5V DC power source is required.

The charger has several fantastic feautures, including intelligent diagnostics and a clear and simple LED display, that will automatically stop the charging process as soon as it is necessary. Because of the hole in the middle of the battery charger, you will easily be able to insert and remove the battery from the charger.

Key Features

Auto on/off

The GP U421 charger is equipped with fully automated electronics and the charging process is fully automated. After completion, it will initially go into the maintenance phase, with minimal current. After a certain period of time, the charging process will stop completely.

Turbo charge

Intelligent diagnostics and charge control will make the charging process incredibly fast, by ensuring that the battery pack is as quick and as cost-effective as possible.

Smart diagnostics

The charger can evaluate whether the inserted battery is empty or damaged. It can also tell if it is already charged. Your batteries will never be over-charged and the charging process itself will be as cost-effective as possible.

Charge everywhere

Because of its USB interface, the charger can be used almost anywhere. You can recharge from a network, from a car adapter, from a USB port on your laptop, from a power bank, or from a plane, train or airport.

Ready to use

These rechargeable NiMH GP batteries are ready for use straight away. This is due both to their productive nature and also to an increased ability to maintain their energy during storage.

Výdrž kapacity 1 rok

With a minimal self-discharge effect called LSD (Low Self Discharge), the battery retains up to 70% energy at room temperature. Recharge the battery again to return to full power.

300 nabíjecích cyklů

Each rechargeable battery is limited by an approximate number of charge cycles. When this number of cycles is reached, the battery capacity, or the battery's ability to conserve as much energy as possible, will drop significantly.

Šetření nákladů

Using rechargeable batteries and knowing how to use them efficiently, can save you considerable financial costs. By buying these batteries, you can save up to €500 compared to the cost of non-rechargeable batteries with equivalent battery life.
