With the Einhell TC-CP 18 Li USB A/C-Solo USB battery adapter and a Power X-Change battery (available separately), you will always have an external power source to hand for your mobile devices. Its two USB ports can be used to charge two devices simultaneously with 2.0 amps each, or to power them with 5 volts. The adapter is equipped with a USB-A port and a USB-C port. An LED indicator on the case of the adapter indicates the operating state at all times. As soon as the battery adapter is switched on via the button and the LED lights up, it can be used to charge or power low-consumption devices. The adapter comes without a battery or charger.
