GP U421 USB + 4x AA GP ReCyko+

New, better, stronger

In 2016, GP Batteries launched a new generation of battery chargers . This type of USB charger brings many benefits. From smaller dimensions, weight and production costs to greater compatibility with various forms of power supply.

These chargers are also equipped with state-of-the-art electronics that control the charging process and many useful functions. Forget the old charging procedures and principles, now it will be a toy for everyone!

USB battery charger GP U421

The latest top charger from the GP Batteries workshop offers many useful features . Due to the development of consumer electronics and the worldwide expansion of the USB platform, you will be able to charge almost anywhere and anytime .

You can power the GP U421 battery charger from the mains, from the cigarette socket of your car, from the USB connector of a laptop, power bank or on the road - on a train or plane . The small size and light weight of the charger will certainly contribute to travel comfort.

The connecting micro USB cable is of course
included in each package. A power supply with 2 A / 5 V DC is required for optimal operation of this charger.

The charger has several modes of operation, including intelligent diagnostics, a clear and simple LED indication that automatically stops charging as needed . Thanks to the hole in the middle of the battery charger, you can always easily insert and remove it and charging the batteries will be a pleasant pastime for you.

Key product features

The GP U421 charger is equipped with fully automated electronics. It controls the charging process itself. After its completion, it first goes into the phase of trickle charging with minimum current and after a certain time it ends completely.

The amazing speed of the charger is combined with intelligent diagnostics and control of the charging process. This ensures that the battery is charged as quickly and gently as possible.

The charger can evaluate whether a non-rechargeable or damaged battery is inserted or whether it is already charged. There is no overcharging of the batteries and the charging process itself is as gentle as possible.

The charger' s USB input interface allows it to be used almost anywhere. You can charge classically from the mains, from the car adapter, USB port of your laptop, powerbank, in airplane, train or airport.

These GP rechargeable NiMH batteries are ready to use immediately. This is due both to their pre-charging in production and also to their increased ability to retain their energy during storage in the sales chain.

Thanks to the minimal self-discharge effect called LSD (LowSelfDischarge), the battery retains up to 70% of energy even after a year of storage at room temperature. When you recharge the battery, you will regain its full capacity.

Each rechargeable battery is factory limited by the approximate number of charge cycles. After reaching this number of cycles, the capacity of the battery will decrease significantly, ie the ability of the battery to store as much energy as possible.

By using rechargeable batteries and handling them properly, you can save considerable financial costs. By purchasing this battery, you will save up to € 500 during normal use compared to purchasing non-rechargeable batteries with an equivalent battery life.

V popisu nabíječky je detekce alkalických baterií. Po zakoupení jsem toto hledal v papírovém návodu a není tam o alkalických bateriích žádná zmínka. Je tedy možné je v tom nabíjet?

Dobrý den, čím to může být, že nabíječka nenabíjí? Někdy zabliká a pak zhasne a baterie nejsou nabité. Jsou některé běžné adaptéry nevhodné nebo je to na reklamaci?
