The PowerBoost 500C is a DC/DC boost converter with integrated LiPo/LiIon battery charger. Convert any 3.7V battery to 5.2V output while simultaneously charging – perfect as a portable power supply or UPS for your projects.

Built around the TPS61090 boost converter, it delivers 500mA+ output (up to 1000mA with a capable battery) with over 90% efficiency. The 5.2V output provides headroom for cable resistance and high-current draws, keeping your Arduino, Raspberry Pi, or other 5V projects running smoothly.

Key Features

Charge and Boost Simultaneously – Use as an uninterruptible power supply
500mA+ Output – Up to 1A with appropriate battery
500mA Charge Rate – MicroUSB input for battery charging
5.2V Output – Headroom for cable loss and high current
Low Battery Indicator – Red LED at 3.2V threshold
Charge Status LEDs – Yellow (charging), Green (complete)
Enable Pin – Disconnect output completely when grounded
iOS Data Resistors – 500mA charge rate for iPhones/iPods
