Feature:
1. Boost + charge control + Lithium battery protection + UPS uninterrupted power supply, multi-function integration, easy to use, no longer trouble the intricate flying lines between the various function boards.
2. The switch can be used as a low power DC mobile power supply. It can be used as a UPS power supply and can be used as a lithium battery charger.
3. Battery box design, easy to remove and replace the battery.
4. Separate charge port, wiring can be placed in any position.
Advantage:
The power supply charges the battery one way while the other way turns on the boost output.
When the power supply is turned on, the battery can be removed at will.
When the battery is powered, the power supply can also be disconnected at any time.
If the power supply or the battery is powered at any way, it can be keep the load continuously and continuously work (UPS function).
When the UPS function is not used, charging the battery can also be used as an ordinary portable power source.
The charging power supply is connected so that the load operation does not occupy the charging current of the battery. The power supply can rapidly charge the battery while being loaded.
Note:
Charging 3/4 pin should be connected to DC5V charging, charging current 500mA max, requires that the maximum power of the charging power supply used is at least 3W higher than the load power consumption, that is, the power supply can also have enough current to the battery while carrying charging.
For example: If the load is ≤ 2W, 5V1A charging power supply can be used.
The SW switch pin can be connected in series to control the boost output circuit to turn on and off. If the switch function is not required, please short connect the SW pin to make the boost path normally open.
Output positive and negative poles 5/6 pin to connect the load, the load normal state recommends ≤ 5W, transient ≤ 8W.
when 5V output, normal load current recommend ≤ 1A, when output 6V ≤800mA, output 9V ≤500mA, output 12V ≤400mA
Lithium battery overcharge protection, over discharge protection, current limiting protection, over temperature protection, output short circuit protection. (If short-circuited due to the fault operation, enter the protection state will not be output, and the connection with 5V charging will automatically activate the reoutput.
Precautions:
There are mos and other components on the board, which can be easily damaged by the soldering iron or by static electricity. Make sure that the soldering iron used is grounded (and the grounding wire is conductive). It is best to wear anti-static gloves.
Package includes:
1 x 18650 Lithium Battery Boost Module (the battery does not includes)
This thing is actually a UPS. Will maintain output with no interruption when either the battery or the input 5V is disconnected.
Charges batteries to 4.1V steady (using protected 18650 cells, always good to be safe). Have not finished testing discharge level yet.

To select the output voltage u need to change some resistors. 1502 and 1103 for 5V | 1202 and 1103 for 6V | 1502 and 2103 for 9V | 1502 and 2873 for 12V |I even made a picture showing all this, but i cant send it in an review because i dont bought it.If someone wants to review this pic i can send the link.

Q:
The width and length are well indicated but what is the height (thickness) of this support?
La largeur et longueur sont bien indiquées mais quelle est la hauteur (épaisseur) de ce support ?
I honestly think it's an automatic interpretation of a Chinese word that means both "key" and something like "sight" - meaning "monitor" or "measure" perhaps? An output for oscilloscope measurements maybe? But I would really like to know for sure!

You connect to the out+ and out- pads. You can connect a switch to the two SW pads to turn the output on or off, or just bridge them to permanently enable the output. The output as supplied is always 5V but id hackable; do a google search for hoe to do this.
