Overview

The Klarus K2 charges almost anything you throw at it — Li-ion, LiFePO4, NiMH, and NiCd cells from AAA up to 26650 — with two independent bays and a selectable 0.5A/1A rate. Its built-in power bank output means you can also top up a phone from the same unit, backed by overcharge, short-circuit, and reverse-polarity protection for safe daily use.

Product Description

Klarus K2 Smart Charger

Two-Way Power: Charge Batteries or Devices

The Klarus K2 is redefining the notion of what a battery charger can be. In addition to charging your batteries, it can also re-purpose them to serve as a heavy-duty power bank for your USB devices. Simply switch your cord from the input jack to the output, hook it up to your smartphone or tablet, and fire up that dead device! Revolutionary input/output circuitry gives you the flexibility to store and discharge power any way you want.

Crank Up the Amps

Double your charging speed! The K2's beefy 1 amp output is ideal for charging high capacity Li-ion batteries. Simply push and hold the button to crank up from 0.5 amps to a full 1 amp charge rate. It’s a handy option to have when you're in a hurry.

Charges Cells of Any Size and Shape

The K2 has a lightweight, portable body that allows you to throw it in any bag. This helps you take advantage of its battery backup capability. Sliding battery contacts allow it to accommodate almost any cell you can imagine, regardless of size. Intelligent circuitry auto-detects your battery's chemistry and adjusts factors like charging voltage and cutoff.
