The widespread use of smartphones and computer tablets has created an increasing need for user-accessible, on the move charging systems. The PowerVerter USB Chargers can be easily installed onto any vehicle in the automotive industry and allow both drivers and passengers to readily access power to charge any device connected via a USB lead. This type of system has the distinct advantage of largely negating the need for mains electricity on vehicles. The 5Volt DC power is much safer than mains, so installation is quick and simple.

Passengers can access the charging facility directly and power their equipment simply through the USB charging lead which is supplied with all such products. All versions in the range can be connected directly to both 12Vdc and 24Vdc systems without adjustment. The advanced electronic design will also automatically detect if the device is an Apple or Android configuration and alter the charging process accordingly. This ensures that whatever device is connected, be it Apple, Android, iPad, phone or tablet, it will always be charged as fully as time and capacity allow.


The PowerVerter USB chargers offer an advanced design that effectively counteracts the voltage drop common when output currents vary as different devices charge at different rates. This avoids the common problem of the phone or tablet indicating it is charging when in fact very little current is being supplied. They also have an exceptionally low quiescent current of less than 2mA meaning that multiple devices can safely be installed throughout buses and coaches without materially discharging the battery.

They have been designed to meet the rigorous standards required for onboard commercial vehicle applications including BS EN50498 and ISO 7637-2 and are both CE and E marked. The casings are made from V0 rated (self-extinguishing) high impact polycarbonate and the electronic assembly is predominantly by computer-controlled SMT for maximum reliability. All versions have a subtle blue LED light to highlight their location on the vehicle.
