Caricabatterie standard britannico N7100 per smartphone Android a tre pin 2A

Dear buyer: 【 Charger Function Introduction 】 1. Negative voltage detection and special voltage growth rate control ensure that the battery is well charged but not overcharged; 2. Output short circuit function. When the output is short circuited, the current is approximately zero, allowing for a prolonged short circuit without damaging the charger; 3. Automatically determine the number of batteries (3-7 strings, 8 strings can also be used, but not guaranteed to be fully charged), and automatically adjust the output voltage; 4. The motherboard reserves a thermistor interface, and the thermistor can be used for temperature control and temperature rise rate detection; 5. LED dual color indicator light, with clear indication and clear current status at a glance; 6. Trickle supplement to ensure the battery is fully charged; 7. Prevent reverse discharge of the battery. When there is no DC power input, the connected battery will leak very little current through the charging board. Loose and simple packaging, black and white piano lacquer, ordinary flame retardant material, IC circuit filtering, overvoltage and overcurrent protection, input voltage: AC100-240V, AC frequency 50-60Hz0.3, output voltage: DC5.0V-2.0A (2000mA), 2A current. It is also suitable for other MICRO interface phones, and the charging speed is much faster. Compared to other chargers, it is generally only 0. or 0.7A, which can save some time and battery. It won't flash either. Please rest assured to use the universal full range of Micro USB interface phones (for use outside of mainland China) Applicable to: 2A models Output interface: USB. Can be replaced with another one. 【 Precautions for using the charger 】 1 If the battery and load work in parallel, please keep the appliances turned off or the load current unchanged during charging. Otherwise, it will cause MCU misjudgment. 2. Please ensure that the input voltage is not lower than the high voltage of the battery, and there is a margin of more than 2V, otherwise it may not be possible to correctly judge and fully charge the battery. 3. Reverse connection of the battery can cause damage to the charger, please pay special attention. 4. reconnecting the battery or reinserting the input power will repeat the entire charging process. 5. To prevent static electricity from damaging the protective board, all personnel and tools in contact with the board must have anti-static measures in place; 6. For indoor use, keep away from heat sources and electromagnetic interference sources, avoid direct sunlight, and avoid dampness. 7. If the traffic lights alternate and flash slowly, and the charger enters testing mode, please unplug the power or battery and reconnect it, otherwise it may cause hidden dangers. 8. After charging, please do not recharge without discharging, otherwise it may cause fatal injury to the battery and even accidents.
