Charge 1.5V lithium AA and AAA cells to a full, stable 1.5V in about 2.5 hours using any USB‑C source. This ensures high‑drain devices stay powered at full strength between swaps.
Status is crystal clear with LEDs: blinking green during charging, steady green when the cells are ready, and red indicating an issue. Charging stops automatically when full, so there’s no guesswork or risk of overcharging.
Refresh up to four batteries at a time. The lid snaps over a molded tray, turning the same box into both a charger and a storage solution—keep everything neat, organized, and ready in a bag, on a desk, or in a car.
1.5V lithium cells maintain their voltage under load, so high‑drain gear doesn’t read as nearly empty. The charger uses a tuned current to fill cells quickly while staying cool, promoting long‑term recharge cycles and reliability over weeks of use.
FlashPulse — Recharge AA & AAA Batteries to Full 1.5V Power in 2.5 Hours
- Drop your 1.5V lithium AA or AAA cells into the slots; the lid presses them into a firm connection so charging starts immediately.
- Connect the box to a USB‑C source (laptop, power bank, wall adapter, or car charger) and begin charging.
- Observe the LEDs: blinking green means charging, steady green means complete, red signals an issue, and charging stops automatically when full.
