Why You'll Love It
- Universal USB Power Input: Powered via USB 2.0 (DC 5V, 1–2A) — plug it into any USB wall adapter, computer port, or power bank you already own.
- 3 or 4 Independent Charging Slots: Choose the slot configuration that suits your needs. Each slot operates independently, so you can charge 1, 2, 3, or 4 batteries at a time.
- LED Charging Indicator: The red LED stays on while charging and remains lit when the charge is complete, so you always know the status at a glance.
- Short Circuit & Overvoltage Protection: Built-in safety circuitry guards against short circuits and overvoltage events, keeping both your batteries and devices secure during every charge cycle.
- Fast & Efficient Charging: 250mA output per slot means a full charge is typically achieved in just 2.5–5.5 hours.
- Compact & Portable: Measuring only 84 × 63 × 25 mm (3.31 × 2.48 × 0.98 in), this lightweight charger slips easily into a bag, backpack, or desk drawer.
- Bonus Battery Storage Box (select option): Optionally includes a handy storage box (62 × 60 × 18 mm) that holds up to 4 AA or 5 AAA batteries. Internal bayonets prevent rolling, external bayonets let you connect multiple boxes together, and color-coded boxes help you distinguish charged from used batteries — all while helping prevent leakage.

Frequently Asked Questions
Q: What types of batteries does this USB battery charger support?
A: The Alasicka USB battery charger is compatible with standard AA and AAA NiMH (Nickel-Metal Hydride) rechargeable batteries. It is not designed for lithium-ion, alkaline, or other battery chemistries. Batteries are not included with purchase.
Q: Can I use my existing USB wall adapter or power bank to power this charger?
A: Yes! The charger uses a universal USB 2.0 connection and requires a standard DC 5V, 1–2A USB power source. You can plug it into any USB wall adapter, laptop USB port, or compatible power bank you already own — no proprietary power supply needed.
Q: Is it safe to leave batteries in the charger overnight?
A: The charger features built-in short circuit protection and overvoltage protection to help ensure safe operation. The LED indicator remains on throughout and after charging. While these safety features add a layer of security, it is always good practice to monitor charging where possible and remove batteries once fully charged.
Q: What is the difference between the 3-slot and 4-slot options?
A: Both options charge AA and AAA NiMH batteries via independent slots, but the 4-slot version allows you to charge one additional battery at a time. Each slot operates independently, so you can use fewer than the maximum number of slots as needed. Select your preferred configuration when adding to cart.
