    The most important feature of these powerbanks is, in my view, the short circuit protection, as many of us have faulty wires, and as li-ion cells can easily provide currents in excess on 10A. This one does have short circuit protection, which actively resets once the short is resolved. As li-ion cells get damaged if discharged below ~3v, it's also important that these cases disconnect the power completely, so that no further discharging may occur (poor quality ones stop boosting the voltage up to 5v, and just leave a direct connection between the battery and USB port - which, if used to power passive consumers, such as LED lights, will result in over-discharging of the cell). This power-bank completely disconnects power once a threshold voltage is reached (~3.1v). Other facts: - output constantly kept at 5V, no matter how small the load. - 0.1 mA draw @ idle

    An unprotected cell (with flat top) fits in well and tight. Output voltage is a bit low when charging devices, about 4.8V at 0.5A. It seems that the step-up converter does not switch off when there is no load, 5V appears always on the output. It draws 0.12mA from the battery when idle. It has a red and a blue LED, the red one flashes when charging the internal battery, the blue one lights up when a load is connected.

    Works well, although it has a rather older chip (CHD-XS-T V1.0). That makes it a little less efficient.
