5V moving charging circuit board step up charing power supply module dual USB inerface suitabloe for Apple Android system

We produce MODULE ! CUSTOM-MADE module is OK! Our company produce your own board!

-----------------------------------------------------------------------------------------------------------------PRODUCT PICTURE

Technical data:

1. Applicable range of battery: 3.7 V lithium battery (including 18650 lithium batteries or lithium polymer batteries) 1000-20000 mah capacity (output current age had better use larger capacity of the battery, a larger battery internal resistance can decrease in parallel with more batteries, please don't use internal resistance is larger).

2. The output voltage and current: dual 5 v / 2.1 A (Max).

3. The output current limit protection: 3 file is adjustable, 1 A, 1.5 A, 2.1 A (start protection will stop after output).

4. Low static current: 0.3 mA, almost negligible.

Due 5. The battery voltage: 4.2-4.3 V (experiments show that the battery charged to 4.2 V can immediately stop charging, the battery such as steady natural dropped will fall about 0.1 V, this shows that the battery is not fully charge, especially when performance superior to import batteries, so this module is set in 4.2-4.3 V, can guarantee the battery fully charge.

6. Due discharge voltage: USB output set of batteries by the discharge voltage is between 3.1 3.3 v, set this value is based on science, depth and the deeper the battery discharge, the shorter the battery life, if the battery fully empty, that also has become the disposable batteries, the battery is the usually set at around 2.8 v li-ion battery protective plate, but according to experience, best value between 3.1 to 3.3 v.

7. In order to make leds more emergency use effect, after the start the under-voltage protection, LED can also be used normally, because the LED power consumption is very small, generally about 10 ma, no damage for the battery, but when the emergency can now! Have you ever seen a fire emergency evacuation drill? In the dark through obstacles!!!!!!!!!!!

8. The charging voltage current: 5 v / 2 a, charging fast! Than the average 5 v / 1 a twice as fast charging of mobile power supply.

Second, the use method (a simple reference images indicate) :

1. The lithium battery in parallel connected meet above requirement, thread to the anode, black connect the cathode.

2. In the MICRO USB port insert 5 v charger (nominal current is less than 2 a charger must with current-limiting protection); Electricity lights will shine surge type, all four lights normally on after the charge, and automatically stops charging.

3. The outlet connected to mobile phone, press 1 button function, began to cell phone charging, (USB1 apple mobile phone, android cell phone USB2).

4. Check the battery, press 1 button function, real-time display lamp battery power, 2 seconds after go out.

5. Open the emergency lighting: even press 2, you can open or close the emergency lighting.

Note:

1. The battery can't meet the polarity, if not carefully to reverse, so there will be a larger current, circuit board hot, so try to touch the lower connection, find abnormal timely correct polarity, normal pick up again after a good battery.

2. The battery leads to short as far as possible, for the whole load more than 10 watts output, the battery must provide 3-4 a current, the lead resistance affects the efficiency of the discharge of the battery is very serious.

3. Because the output power is larger, so the taller also to the requirement of the battery, try to choose battery internal resistance in 100 milliohm, if the internal resistance is big, and several battery as much as possible, please. In order to reduce the internal resistance.

4. This module 2 usb port respectively set two mobile phone recognition mode, if it is found that does not recognize, please replace a usb oral examination, also not line, can only take your cell phone special identification circuit connector, adapter.
