    Tomo T4
    Color:White
    Pros:
    Doppio utilizzo, carica batterie e Powerbank. Possibilità di poter scegliere le batterie 18650, e quindi la capacità di mAh, ma anche la qualità delle batteri atterie stesse in base al marchio. Spesso molti powerbank sono dotati di batterie scadenti. Il Tomo t4 funziona anche inserendo una sola batteria.
    Possibilità di poter sostituire rapidamente le batterie scariche con altre cariche se si dispongono di più di 4 batterie, una comodità all'occorrenza per chi si trova a lungo all'aperto e ha necessità di ricaricare smartphone etc. Tutto sommato compatto come dimensioni, alcuni powerbank con stesse capacità di mAh sono anche più grossi. Display simpatico che indica il livello di carica delle batterie, e l'amperaggio in uscita in fase di carica di un device.
    Cons:
    Forse un pò il peso inserendo tutte e 4 le batterie negli slot, ma è normale.
    Il 90% del peso complessivo dipende propio dalle batterie.

    Vraiment pas cher / Very low cost
    Color:Black
    Pros:
    J'aime bien l'affichage de chargement des batteries qui ne sont pas fournies. J'ai ajouté des batteries de 9600 Ah. Tout va bien pour le moment.
    Pour insérer les Batteries, il suffit de faire coulisser la coque supérieure. Rien e plus facile.

    I like the display of charging batteries that are not provided. I added 9600 Ah batteries. All is well for the moment.
    To insert the Batteries, simply slide the upper shell. Nothing easier.
    Cons:
    Batteries non fournies mais cela est spécifié dans l'annonce du produit

    Batteries not supplied but this is specified in product announcement

    Color:Black
    Pros:
    This power bank is small and good looking. Comes with a very nice package. The price is very good for such an item. You can put inside up to 4 18650 batteries, so the real capacity could be over 12 000mAh. This 18650 batteries could be easy replaced, could be charged inside too. This TOMO power bank has display showing capacity level for each battery.
    Cons:
    I put inside 4 batteries of about 2000mA each and I charged my mobile from 20% to 100%. My phone acu is about 4000 mAh. I think I could easily charge it from 0% twice. The display show voltage and each batterry level. The best thing is that I can put new 18650 battery when those inside is discharged.

    TOMO T4 DIY Smart Power Bank
    Color:Black
    Pros:
    Can use and as power bank and as charger.
    If, in the future, will have problem with battery, anybody can will replace it easy and continue using.

    Может использоваться и как блок питания и как зарядное устройство.
    Если в будущем будет проблема с батареей, любой может легко заменить их и продолжать использовать.
    Cons:
    A little rough in the design. But as they say - "Every man to his own taste"

    Немножко грубовата в дизайне. Но как говорится - "на вкус и цвет товарищей нет".

    DIY power bank
    Color:White
    Pros:
    Well build, probably as compact as you can get a power bank with four slots and a smart chip.
    It can actually charge zeroed batteries, which is nice, so you can actually revive batteries that you accidently let overdischarge.
    Display is bright and easy to read.
    Cons:
    Display may be a bit too bright sometimes and there's no way to adjust the brightness. It's either on or off.
    Battery charge is just graphical, couldn't find an option to show it in percentage.

    Great deal
    Color:White
    Pros:
    this product is specially useful when you have used spare ion cells from a used computer battery, I now built a powerbank form litterally trash, so it's eco friendly (:
    Cons:
    It takes a little longer than i expected to fully charge cells but it is ok, i don't use this power bank every day, just sometimes when my cellphone discharges and i don't have any plug near to me
