Description
The TrustFire TR-003 Charger 4-Slot 500mA for Li-ion Batteries is a versatile charger designed for cylindrical lithium-ion batteries, ideal for powering flashlights, vape devices, and other electronics. It can charge four 18650 batteries simultaneously, ensuring your flashlight is ready for a night hike. With dual input options and independent charging slots, it offers reliable functionality. Featuring a 1-year warranty, this charger suits tech enthusiasts, campers, and everyday users.
Reliable Charging for Li-ion Batteries
The TrustFire TR-003 Charger is compatible with a wide range of cylindrical lithium-ion batteries, including 10430, 10440, 14500, 16340, 17670, 18350, 18500, and 18650 sizes. It supports two input options: AC 100-240V (50/60Hz) for home use and DC 12V 2A for car charging, making it versatile for travel or outdoor use. Each slot charges independently at a constant output of 4.2V and 500mA, ensuring consistent charging across all slots. The charger automatically stops when charging is complete, but some reviews indicate it may continue a trickle charge, which could wear down batteries if left plugged in for too long. It lacks support for NiMH batteries, and its charge rate may be too high for smaller cells like 10440, potentially posing safety risks.
Durable and Compact Design
Constructed with a durable plastic housing, the TrustFire TR-003 Charger offers a lightweight build at approximately 150g (without cables), making it easy to carry for travel or outdoor use. It measures roughly 140mm in length, 57mm in width, and 28mm in height, ensuring a compact footprint that fits well in a bag or on a desk. The charger features four independent slots with spring-loaded sliders to accommodate various battery sizes, and each slot has an LED indicator (red while charging, green when complete). Its dual input ports (AC and DC) enhance versatility, but the lack of a clear low voltage cutoff can be a concern for battery longevity.
Designed for Electronics and Outdoor Use
The TrustFire TR-003 is tailored for tech enthusiasts, campers, and everyday users needing a reliable charger for Li-ion batteries during outdoor activities or emergencies. It can charge four 18650 batteries for a flashlight, ensuring you’re prepared for a night hike.
