    very good product!
    this Tomo S4 power bank/18650 charger is very practical, made with good materials and also with a very good finish! the plastic is thick and solid, springs & contacts are very high quality, this S4 is built to last...the display is very cool & usefull, this power bank is well sophisticated but very simple to use...the supplied cable is a bit short BUT really thick & good cable, no problem with 2amp, and it's by far the most important thing.
    Thank you Gearbest!

    TOMO S4 Power Charger
    Хороший зарядник, помещаются в него батареи с защитой.
    Из плюсов это:
    Зарядка каждой батареи отдельно, удобная индикация, удобный корпус, быстрый доступ к батареям.
    Из минусов, издает неприятный писк часто при работе. Порт 1А не работает нормально, он не останавливает ток на 1А и потому постоянно уходит в разрыв.

    В целом, для моих целей он подошел отлично

    recommended without tinees the batteries
    I already had one of the brand but I'm hurting the cargo entry.
    This gives me the impression that the charging points are better welded, than if one tenog is damaged another 2 to load.
    It is more compact than I thought.
    I like that the screen dies how much charge speed it transfers.
    I just had a heating problem, and it was on hot ground, I put it to charge and at the same time I connected two phones to charge, but after that I did not repeat it and it still works very well.

    unique power bank/18650 charger
    Item as described, shows output voltage and current very precisely, and works with solo one or more (up to four)18650 batteries. easy to operate and universally designed, supports ligtning, micro usb, and usb-c charging cables. Output is via 2 USB ports, one has output of 2A max, other one 1A. LCD is back-lit, but light can be turned off tapping the power button once. Build quality is fine
    Suggestion
    a bit pricey

    Great
    I wanted a way to charge my electronic cigarette through usb-c port. This device does that perfectly (you can also use lightning and micro-usb). And of course you can use it as an external battery pack. So that's exactly the kind of stuff I like to find on Gearbest, I'm happy about it. It's worth mentioning that it can't be charged through a usb-c to usb-c cable neither can it charge stuff through that kind of cable (no usb PD).
