This Hahnel battery charger can be used to wirelessly charge your smartphone. It can also be used in conjunction with a Hahnel Powercube to allow charging of all of your devices simultaneously. This charger is compatible with Smartphones that utilise wireless charging (iPhone X, 8, 8+ & various Android models.) There are various methods in which to use the Hahnel Powercube Wireless charger. You can use it as a stand-alone desktop charger by attaching it to your computer, you can connect it to a suitable QC-enabled device via the Micro USB socket which enables 9V charging, or you can use the included short USB cable to a Hahnel Procube charger. This last option allows you to charge your smartphone and camera battery at the same time. *9V charging is much faster than standard 5V USB charging. 9V charging requires a QC-compatible adapter to be used. Your Smart device must also have a high-performance wireless receiver that is compatble with higher 9V charge power.
