A USB interface device called snappower is raising funds on crowdfunding websites.
This device is plug into the wall power socket, plug and play, which can provide a USB charging interface to charge mobile devices such as smartphones, tablets, etc. without changing the wall power socket wiring or using clumsy wiring boards. Snappower provides a USB charging interface on the side, not on the front, so that the USB charging cable can be more suitable for the wall around the power outlet and provide a clean environment for use.
Snappower USB interface output current is slightly lower than 1 Amp, compatible with all USB devices, charging smart phones is about the same as normal USB charging, but charging for tablet computers may take longer. Snappower has crowdfunding done on KickStarter and will be shipped in August, with 1 snappower crowdfunding price of $12 and 2 snappower crowdfunding at $20.
