    Convenient power block case, was able to repurpose some old laptop cells and make an excellent off-grid charger. I took some cells from a dead laptop battery pack, taking care not to short out any of the terminals (the 18650 batteries can pack a considerable punch, even when unused for a considerable time) Not only does this let me boost charges on mobile phones and tablets, but it's great for powering Arduino, Raspberry Pi and Wireless Webcam projects.

    It's a nice battery charger. It has one input USB port on a side to recharge the battery bank and three USB outputs to charge USB external devices. It shows the charge level in %. I bought two of them. Found only one quality issue- cannot close the lid with or without the batteries. Will have to use to scotch, I guess, to keep it in one piece.

    Had an old 9 cell laptop battery with one dead cell, was able to carefully dismantle and put the good units directly into this, now I can recharge my phone, tablet and other electrical equipment several times on the go. ideal for long weekends, have even used it on Raspberry Pi and Arduino equipment Well worth the money, far cheaper than buying a box, charger unit and battery holder separately - really useful

    This little box is very easy to fill with batteries. It is importend that the batteries are all the same, preferable of the same manufacture. All batteries are connected in parallel. I am very satisfied with charger.

    looks good, almost like a branded product. Should have been 8 slots for the price, works well

    Well received, not tested yet.

    The capacity would depend on the quality of batteries you put in it.
