A smart two-slot charger that works with almost all rechargeable outdoorsy batteries, ranging from 1.2 V to 3.7 V, 4.2 V, and 4.35 V. You can also have different battery types in each slot and it won’t charge them to death. This is the updated version of their old i2. The most visible improvements are the new display and the doubled charging speed (up to 1A).
The package includes the charger, AC adapter, and the user guide but no batteries in case someone was wondering. The two charging slots charge and control independently. The device automatically identifies the battery type, detects the battery power status, and displays charging progress. It has reverse polarity protection and anti-short circuiting protection incorporated. It also automatically stops charging when the batteries are fully charged, so it doesn’t devour their souls like the ancient, evil chargers used to do. It also notifies you to discontinue charging when you accidentally insert a non-rechargeable battery into the slot.
The charger is made from fire-resistant and flame retardant polycarbonate and certified by RoHS, CE, FCC, and CEC.
You can charge the following rechargeable battery types with this charger.
10340, 10350, 10440, 10500, 12340, 12500, 12650, 13450, 13500, 13650, 14350, 14430, 14500, 14650, 16500, 16340(RCR123), 16650, 17350, 17500, 17650, 17670, 18350, 18490, 18500, 18650, 22500, 22650, 25500, 26500, and 26650.
