    The battery case with UPS module is for two 18650 Batteries (not included). It comes with a short USB to USB-mini cable. Its length is about 18 cm. That module has four red LEDs, showing actual capacity with steps of 25%. When loading the LED blinks until fully loaded. It is possible to get current while loading that module.

    The units overall appearance is good. The UPS function appears to work well. Unfortunately the mini USB connector was bent when it arrived, I was able to straighten it enough to be able to insert a charging plug, I can see that I will need to replace the connector sometime soon.

    Actually this is not an UPS(Uninterrupted Power Supply) since it will drop the voltage momentarily when input is disconnected causing whatever is connected to reboot or power off. The solution proposed by some, to solder a 470uF capacitor to the 5v output will not work on devices that have an average demand for current(this is for the 5v/9v/12v version). Having said that, the quality of the board is good and it can charge and deliver the current as expected. Can work as a traveling power supply or

    Megérkezett! Észrevételem: az 5V-os kimenet töltés nélkül tökéletes 5.1V viszont töltés közben 4.5V-ra vissza esik a kimeneti feszültség az 5V-os kapcson és az USB porton!

    Підключив до Малинки, працює, але хотілося б ще кейс до нього. Приклеїв на плату повстяні ніжки, поки що буде так.

    Works great! Step up voltage is a bonus for matching with what ever product that needs a standard battery replacement.
