Xiamen Nanfu Digital Technology Co., Ltd. specializes in the development and production of smart chargers. Its charging technology has obtained three national utility model patents with patent numbers: 200520082851.1, 2000620167978.8, and 200620167389.X.Xiamen Huan Gao Smart Charger has fast charging speed, automatic stop function that is accurate and reliable, high cost performance advantages, and is quite suitable for various capacities/types of rechargeable batteries Comparison between HuanGao Smart Charger and Ordinary Charger Produced by Xiamen Nanfu Electronic Technology Co., Ltd 1。Xiamen Huan Gao Smart Charger: Can quickly fully charge the battery with light indication, fully charged within 5 hours. After full charge, it switches to trickle charging for long-term plug-in use, convenient for users and maintains power.Ordinary chargers have low charging current and typically take over 10 hours to charge. Users need to plan ahead and arrange charging time well in advance, and must unplug the power source to stop charging on time, which is very inconvenient to use. 2。Xiamen Huan Gao Smart Charger: Utilizes patented technology with multiple detection and protection features, capable of quickly and accurately charging the battery fully, automatically stopping without damaging the battery, extending its lifespan.Ordinary chargers need to calculate charging time based on the battery's capacity and stop charging at the corresponding time. Due to various reasons, the actual capacity needed to be replenished by the battery is not the nominal capacity, making it impossible to accurately calculate the charging time. This can either overcharge or undercharge the battery.The result is a rapid reduction in battery life or damage.This causes inconvenience for users due to poor battery performance and financial losses. 3. Xiamen Huan Gao Intelligent Charger: It can automatically identify different types of batteries, such as lithium batteries, nickel-cadmium, nickel-metal hydride batteries, etc., and intelligently choose the charging method When charging, the red light turns orange, and when the battery reaches the critical point of fullness, it enters a variable-speed flashing state, automatically lowering the charging speed to ensure complete battery filling. Once fully charged, it switches to a green light. Xiamen Huan Gao Dual Slot Charger.

If the battery performance is basically okay and placed correctly, the light will turn green; if the battery is damaged including over-discharge or reverse polarity, the light will not turn on. Charging—“red light on”; fully charged—green light on and stops automatically * The input voltage is designed to be a universal mains voltage range Input Voltage AC: 100-240V Charging current DC: 500mA for single cell, 1A for dual cells Output voltage: 4.2V±1% Principles and Warnings *The battery must not be installed upside down, otherwise it may be damaged *The charger does not initially charge over-discharged batteries; it starts charging after a period of trickle replenishment *Only for indoor use, do not use in high temperature/humid environments, do not invert or cover while charging If it doesn't charge, it could be because the battery is full, aging, short-circuited, installed backwards, inserted with ordinary batteries, or has debris inside The total price of the goods is greater than 200 yuan or the total number of goods is greater than 50 pieces Our store's products are all mixed batch, and the mixed batch amount only needs to be over 200 yuan.
