TrustFire TR-001 Charger for Li-ion Batteries 500mA Dual Slot Description
The TrustFire TR-001 Charger for Li-ion Batteries 500mA Dual Slot is a versatile charger designed for charging Li-ion batteries, ideal for outdoor activities, vaping, and emergency preparedness. For example, it can charge two 18650 batteries for a flashlight during a camping trip, ensuring reliable power for nighttime use. With a dual-slot design and 500mA output, it offers dependable functionality. Featuring a 1-year warranty, this TrustFire TR-001 for Outdoor Use suits vapers, campers, and electronics users.

Efficient Charging for Outdoor and Everyday Use
The TrustFire TR-001 Charger is a dual-slot charger compatible with a wide range of Li-ion batteries, including 10430, 10440, 14500, 16340, 17335, 17670, 18350, 18500, and 18650 sizes, supporting both 3.7V (LiCoO2/LiMn) and 3.2V (LiFePO4) chemistries via a selectable switch [Ref web:0] [Ref web:1]. It delivers an output of 4.2V at 500mA per slot, with each slot charging independently, indicated by red LEDs during charging and green LEDs when the voltage is high enough (typically 4.2V for 3.7V batteries or 3.6V for 3.2V batteries) [Ref web:0] [Ref web:1]. The charger supports wide input voltage (AC 100-240V, 50/60Hz) and can also be powered via a 12V DC car adapter (not included), making it versatile for home or travel use [Ref web:0] [Ref web:1]. It features a spring-loaded slider for secure battery contact, accommodating flat-top batteries and lengths from 31mm to 69mm, though charging times can be slow for larger cells like 18650s (up to 17-19 hours for 2600-3400mAh cells) [Ref web:0] [Ref web:3]. The charger continues to trickle charge after the LED turns green, which some users note can overcharge if batteries are left in too long, recommending removal within a few hours of the green light [Ref web:0]. This makes the TR-001 suitable for outdoor and everyday use, though users should monitor charging times and avoid prolonged trickle charging.

Durable and Compact Design
The TrustFire TR-001 Charger is constructed with a plastic housing, offering a lightweight design for portability in outdoor settings, such as during camping or travel [Ref web:0]. It measures 138mm in length, 58mm in width, and 28mm in height, weighing approximately 99g without the power cord, making it compact enough to fit in a backpack or glove compartment [Ref web:8]. The charger includes a US mains cable (other plug types like AUS, UK, or EU are optional), but lacks an instruction sheet, which some users find inconvenient [Ref web:0] [Ref web:1]. It features a DC barrel input for 12V car charging (adapter not included) and a switch to toggle between 3.7V and 3.2V battery chemistries, though some units may lack this switch, defaulting to 4.2V [Ref web:0] [Ref web:14]. The charger produces a weak rattling noise when powered, not due to loose parts but likely from internal components, which does not affect functionality [Ref web:0]. It passed a 2500V isolation test but failed at 5000V, making it safe for 110VAC use but less reliable for 230VAC environments [Ref web:0]. This makes the TR-001 a compact choice for charging, though users in 230VAC regions should exercise caution, and all users should ensure proper battery chemistry settings.

Designed for Outdoor and Everyday Use
The TrustFire TR-001 Charger for Outdoor Use is tailored for vapers, campers, and electronics users needing a reliable charger for Li-ion batteries during outdoor activities or emergencies. For example, it can charge two 18350 batteries for a vaping device or flashlight, ensuring power availability during a hiking trip, though its slow charging speed (up to 19 hours for a 3400mAh 18650) may require planning for larger cells [Ref web:0] [Ref web:3]. The dual-slot design with independent charging allows for simultaneous charging of different battery sizes, but some users report reliability issues, with occasional units failing after initial use or not fully charging batteries (e.g., green light at 1/3 charge due to incorrect voltage settings) [Ref web:4] [Ref web:12]. The charger automatically stops major charging when complete but continues a trickle charge, which can be mitigated by removing batteries shortly after the green light appears [Ref web:0] [Ref web:1]. It’s ideal for those needing a budget-friendly, versatile charger for outdoor and everyday use, offering compatibility with various Li-ion batteries, though users should monitor charging, ensure correct voltage settings, and be prepared for potential quality variability.
