    The TOMO V8-4 power bank feels solid and well made, but it doesn’t feel like a premium product. The volume is large enough to hold ~8 cells, rather than four, which may be an issue if you are space constrained. The weight though, is reasonable. It fits four 18650 cells. I estimate that it can take cells up to 68.5mm length, and probably 69mm.

    The power bank is turned on by pressing a button on the back, next to one of the USB outputs. It also powers itself up automatically when when a USB device or charger is connected.

    When powered on, the display indicates the approximate level of charge of each individual cell
    When powering USB devices, the right-hand side of the display indicates which port(s) are drawing current. The representation of each port has an animated indicator line that sweeps from left to right to indicate current flow. It isn’t clear to me whether or not the speed of the animation hints at actual current.

    I’ve had some challenges when trying to measure current delivery to USB devices.

    When used with a resistive 5 or 2.5 Ohm load, which should draw 1 or 2 A, respectively, at USB voltages (5V), the powerbank delivers current, but behaves strangely. The display shows intermittent or non-existent current draw through the port the load is connected to, and will power itself down after a time-out period as if nothing was connected.
    When the load is connected to the 2A output though a USB voltage and current meter, it shows a draw of ~0.95A @4.88V with a 5 Ohm load and ~1.9A @ 4.8V with a 2.5 Ohm load.

    On the 1A output, though a U
    I really wanted to love this power bank, but it comes up a little short.

    Dopo averlo usato per un po' di tempo, posso dire che funziona bene. Sul display è possibile leggere il consumo in mah e quando non c'è niente collegato indica il livello di carica di ogni singola batteria.
    Per usarlo non è necessario accenderlo, infatti appena inseriamo un cavo usb dopo pochi secondi si accende da solo e dopo averlo staccato in 20 secondi si spenge da solo.
    E' possibile montare batterie li-ion 18650 sia protette che non protette anche di diverso amperaggio.
    Quando è acceso con una pressione veloce del tasto accensione è possibile spengere il display.
    Il circuito interno ha una protezione per batterie alla sosvraccarica e sotto carica.
    Per caricare le batterie basta utilizzare un caricabetterie da smartphone collegandolo al connettore microusb.
    Per la sua semplicità di utilizzo lo consiglio a tutti questo prodotto.

    Good charger, good power bank, awesome battery case
    This thing is great, It is not much wider than a case for 4 1850's.
    It is a bit longer on both top and bottom, the electronics have to go somewhere :).
    The great thing is, that it shows me how much charge my batteries have, so I know exactly which ones are full and which are not.
    You can charge your phone, tablet or whatever else you have with either the 1A or 2A output on the back.
    There is also a switch to turn the screen on.
    About 3 seconds pressing it will turn it on. If you then press it short, the light of the screen will turn off.
    This is useful if you are charging with it.
    none so far

    Excellent powerbank
    1. Good plastic for case ( does not stink, durable );
    2. there is reverse polarity protection
    3. individual work with every battery. Thus it is possible to install batteries of different capacity and different charge level.
    4. there is a possibility to charge the batteries. In the campaign I charge the car batteries for the flashlight.
    5. not very quick battery charge. But it is a feature of the use of micro USB.

    Summary : very good product
    1. short cable. Same power bank Soshine E3 have cable with length 45cm.
    2. in standby mode it consumes 14 mA
    3. Not a minus, rather a feature. It not only discharges the battery to 3V. Thus new batteries with a lower limit of discharge of 2.5 V will be used not 100%.
    4.When you use the user with a current of approximately 2A is better to use 3-4 battery, because When you use a 1-2 accumulator spring is very hot. For me it's not a problem ,because once I use all 4 slots.
