TrustFire TR-003 Charger 4-Slot 500mA for Li-ion Batteries 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. For example, 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 TrustFire TR-003 for Electronics Use suits tech enthusiasts, campers, and everyday users.
Reliable Charging for Li-ion Batteries
The TrustFire TR-003 Charger is a 4-slot charger 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, though some users have noted slight variations in charging current (e.g., 0.63A to 0.67A for a 3.16V 18650, dropping to 0.51A with two batteries), as reported in web information. 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, as cautioned in web information. This makes it a practical choice for charging Li-ion batteries, though users should remove batteries promptly after charging and avoid using it with smaller cells like 10440.
Durable and Compact Design
The TrustFire TR-003 Charger is constructed with a durable plastic housing, offering 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), though some users have reported missing bolts in their packages, affecting assembly, as noted in Amazon reviews. Its dual input ports (AC and DC) enhance versatility, but the lack of a clear low voltage cutoff (continuing to charge even after completion) can be a concern for battery longevity, as highlighted in web information. This makes it a durable, compact choice for charging Li-ion batteries, though users should ensure all components are included and monitor charging to avoid overcharging.
Designed for Electronics and Outdoor Use
The TrustFire TR-003 for Electronics Use is tailored for tech enthusiasts, campers, and everyday users needing a reliable charger for Li-ion batteries during outdoor activities or emergencies. For example, it can charge four 18650 batteries for a flashlight like the XTAR B20, ensuring you're prepared for a night hike, though its 500mA charge rate per slot is relatively slow for high-capacity cells (e.g., 3400mAh 18650s may take 6-7 hours), as noted in web information. The charger's independent slots and dual input options make it versatile for home or car use, and its compatibility with various battery sizes suits a range of devices, though it lacks support for NiMH batteries and may not be safe for smaller cells like 10440 due to the high charge rate, as cautioned in user feedback. It's ideal for those needing a budget-friendly charger for Li-ion batteries in outdoor and everyday scenarios, offering a balance of capacity and convenience, though users should avoid overcharging and verify battery compatibility to ensure safety.
