    Pros:
    This is the second TOMO power bank I bought... working very well with quality batteries. This comes with no battery, but price is good, high quality, not too big in your pocket.
    Cons:
    none for now

    Pros:
    Very pleased with this Smart Power Bank. It works well and does what it promises. I have not used it a lot to charge any of my devices but it did charge my phone quite quickly and well. Primary use is as a 18650 battery charger. This feature is great. It detects incorrect polarity and charges batteries individually and gives a nice detailed display of the charge and progress. A very good multi purpose Smart Bank and Charger. I highly recommend this product.
    Cons:
    Batteries left inside the Charger Smart Bank do discharge a bit over time if not in use.

    Pros:
    kleines Gerät mit mehrfachem Nutzen:
    - lädt bis zu vier 18650er Akkus
    - Powerbank mit 1x 5V 1A und 1x 5V 2A USB
    - aufgrund der geringen Größe auch als Transportbox für Akkus nutzbar

    informatives, beleuchtetes (abschaltbar) Display, zeigt beim Laden graphisch den Ladestand/-vorgang sowie Verpolungsschutz der einzelnen Akkus und beim beim Entladen Volt und Ampere an der jeweiligen Buchse an

    gute Verarbeitung und ansprechendes Design
    Cons:
    mitgeliefertes USB-Kabel mit ca. 24 cm relativ kurz, könnte sich aber auch als praktisch erweisen ;)

    Pros:
    Charge des batteries intelligente, je l\'utilise avec un mini panneau solaire: selon la puissance d\'entrée ce boitier réparti la charge sur 1,2,3 ou 4 batteries, SUPER

    Permet de visualiser le courant de décharge sur chacune des 2 sorties.

    Tout est conforme au descriptif

    Génial
    Cons:
    le bouton ON OFF n\'est pas de très bonne qualité, ça fait un peu plastique bas de gamme

    Pros:
    Just add your own batteries and you have a power bank to carry or can be used to charge the batteries for use in other things
    Screen shows status of each battery when charging or when switched on with no load connected.
    When charging devices from this it lets you know the current that the device is drawing.
    Two outputs, one 1 A and the other is 2A
    Cons:
    None
