Penelope X. ★★★★★ Aug 17, 2026

The 1900mAh capacity is spot on for my headlamp, and the 3.8V output keeps the beam steady until the very end. It charges fast through the USB port, which is way more convenient than digging out a separate cradle.

Bought this as a spare for my headlamp and the 1900mAh capacity has been plenty for a full night of trail use. I like that it charges right from the USB port without needing a separate charger. Solid little battery.

Andrew ★★★★★ Aug 12, 2026

The USB charging port is a game-changer for me—no more carrying a separate charger on camping trips. The 1900mAh capacity easily got me through a week of evening use in my headlamp, and the 3.8V output feels solid. Wish it came with a case, but it’s a tiny quibble.
