Applicable models: as long as your machine can be charged on the computer''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s USB.You can use this emergency charger to charge. The voltage/current output standard is the same as the computer''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s USB 5V/500mA
With particular emphasis on:
1. This is aEmergencyCharging is good to solve emergency problems, but daily charging is not recommended. It is inappropriate to use as a power bank or mobile power(Although it has this function with enough batteries, it is not cost-effective.^_^)
2. This charger comes standard with only one charger,No USB charging cable or dry battery.
3. Measured results: buy two Nanfu batteries with a production date of just over one month(Personally, it should not be fake), Charge my own Apple 4S, turn it on, turn on the screen(hehe, I want to see the battery percentage and time)I answered a phone call on the way, charged for half an hour, and charged nearly 20% of the battery, and then continued to charge for about half an hour. The device does not support charging. It is estimated that the voltage is too low and there is no battery. Charge it in the next half hour Slowly, fill in 10% in half an hour,If it is turned off or does not turn on the screen, or if there is no callThere should be more battery power. After unplugging the USB cable, the flashlight is not on. It can be seen that the battery is almost exhausted.(After a few hours, these 2 batteries will still have a small amount of power to use, and you can also turn on the flashlight. The dry batteries are used at intervals, hehe, but the power will be very small and not durable, and can only be used for listening The radio is coming).Overall feeling: emergency(Going out for a long time, or if the phone is out of power temporarily, you need to make calls or other functions)A nice baby.
4.Not suitable for tabletsAnd other charging, they have higher requirements for current, this little baby only providesMaximum voltage 5V, maximum current 0.5ABefore buying, please check the input voltage and current that your machine can support.
5. Measured NanfuDry cellAfter charging the iphone for 10 minutes, the dry battery will heat up. In half an hour, the dry battery is very hot, but don’t worry, because the dry battery is powered by chemical reactions.Rapid discharge will react faster and generate heat, whileSo during chargingPlease be sure to keep ventilation and no flammable objects and other debris around the charger.
6. This little baby is very practical. We are selling with very thin profit. If you receive the baby, it feels okay, pleasePraiseSupport the shop, if you have any questions, please contact us in time, we will do our best to meet your requirements.
technical parameter:
1. The design is based on two batteries, the most common AA/AA battery(The actual measurement found that a battery of 5 cents 1 cell can''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''t be charged at all, and it is recommended that it be at least Nanfu''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s battery)
2. Built-in protection circuit, when the battery in the charger is exhausted or the device''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s lithium battery is fully charged, the charger will automatically disconnect and stop charging!
3. Built-in DC-DC boost circuit. 2 batteries, 3V boosted to 5V, about 2 times conversion efficiency about 88%, output capacity about 60% of battery capacity(Capacity/2*88%=60%), Such as two AA batteries with a capacity of 2350mAh, the output capacity is about 1000mAh).
4. Input voltage: 2.0-3.0V
5. Output voltage: 5.0V
6. Output current: 700MA maximum
8,Shipping list:One charger(Does not include USB charging cable and battery).
