MagTech PowerPack™

Great, except that the magnets need to be stronger to stop them coming away from the charger and remaining in the phone socket when you disconnect it.

Be aware that the connection may not work if the device is in a case, although perhaps the case could be enlarged to accommodate it. It is a handy size for carrying.

Connector gets stuck in phone jack..too hard to remove. There is no way to store extra connectors with powerpack.
