Wall Power Adapter: 5.25VDC, 2.5A, 20AWG MicroUSB Cable

Improved version available! This product has been replaced by the Wall Power Adapter: 5.15VDC, 2.5A, USB Micro-B Connector, 18AWG 1.5m Cable.

This UL-certified AC-to-DC converter gives you an easy way to deliver up to 2.5 A to your USB-powered device from a US-style AC electrical socket. It has been specifically designed to supply 5.25 V instead of 5 V to help ensure that the device it is powering receives close to 5 V even when the current draw is high. Since the USB specification allows supply voltages up to 5.25 V, this adapter is safe for use with compliant devices.

The adapter features a US-style two-prong plug and works with input voltages from 100 VAC to 240 VAC, and it features a 1.5 m to 1.8 m (5 ft to 6 ft) DC power cord with 20 AWG wires that is terminated by a USB Micro-B connector, which makes it great for powering devices like a Raspberry Pi (especially newer Raspberry Pi models, like the Pi 3, which can draw a lot of current!).

Note: This adapter might not be suitable for powering all USB-powered devices as some USB devices go into suspend mode if they do not see activity on the USB data lines. If the device is configurable, you might be able to disable this suspend functionality so that it can run while powered from an adapter like this.
