Milwaukee-based Kickstart Design has launched a charge-and-boost module designed for 3.7-4.2V lithium-ion or lithium-polymer batteries, and it promises plenty of power: the AmpRipper 3000.

"The AmpRipper 3000 is a next-gen power supply for all your portable/rechargeable projects," Kickstart Design promises. "With narrow VDC powerpath management and a 9A peak switching current, you’ll be able to power your high-current projects and fast charge your battery with a single module."

The aggressively-named AmpRipper 3000 is built around the Monolithic Power MP2624 4.5A single-cell battery charger IC, linked to an MP3423 9A synchronous boost converter. A key feature: Seamless transition between charge and discharge modes, meaning the board is suitable for use as an uninterruptible power supply (UPS) as well as a battery power system.

As well as a connector for an external battery — you can use "most 3.7-4.2V lithium-ion or polymer batteries," the company notes, "but to get the most out of this product please use batteries with ≥3000mAh capacity and high discharge capacity (≥2C)" — the board includes two USB Type-C and one USB Type-A ports. The two USB Type-C ports are configured as upstream and downstream facing ports respectively, while the Type-A output is a dedicated charging port.

"This configuration works with most 5V USB-A/C 2.0 and 3.0 devices," Kickstart Design warns, "but may not work with some proprietary devices. Both USB-A/C outputs can be connected at the same time, but keep in mind that the total output power is divided."

The AmpRipper 3000 is now available from Kickstart Design's Tindie store, priced at $37.99 bring-your-own-battery.
