ou no longer need to haul a bulky dedicated cradle charger on trips just to juice up high-drain cylindrical cells. Acebeam has launched standalone retail sales of its AB21CP6425 battery—a popular 21700-format cell priced at $25. Previously, this power source was only available bundled with the brand's premium flashlights.
The standout real-world feature is an integrated USB-C port built directly into the battery casing. You can plug it straight into a standard phone charging cable, eliminating the need for a specialized external charger. A built-in LED indicator keeps track of the process: it glows red while charging and flips to green once full. Maintaining standard 21700 dimensions (21 mm in diameter and 70 mm in length), the cell delivers a continuous discharge current of up to 25A, comfortably driving high-drain searchlights, compact power tools, and DIY electronics without voltage drops.
In terms of runtime, the cell outpaces typical competitors with an impressive energy capacity of 22.4 Wh (6,400 mAh at an average 3.5V). For $25, buyers get a high-density power source that recharges via any standard phone adapter, cutting down backpack clutter on the go.
