Adafruit 5V 1A (1000mA) USB port power supply - UL Listed

Need a reliable USB jack for charging or powering projects, without needing a computer? This switching supply provides a clean, regulated output of up to 1000mA, compatible with 110 or 240 input. Ideal for global use.

The design offers a US 2-prong style plug, easily paired with an adapter from any hardware store. Engineered to deliver 5.25V instead of 5V, it compensates for voltage drops seen in USB-powered devices due to cable resistance.

Safe for all 5V electronics, this adapter ensures optimal performance within the full current range, irrespective of cable thickness. It features a USB 'A' type port for cable versatility, with data line resistors matching Apple chargers. Tested successfully with an iPhone 4, it is compatible with devices that use iPhone adapters.

This adapter suits projects involving Arduino, Raspberry Pi, and similar microcontrollers. It also supports lithium-polymer battery chargers. A convenient red LED indicator signals it is operational. Suitable for charging needs wherever USB 5V is required.
