        Mr
        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.

        Cons:
        Innenleben etwas wackelig, man sollte es besser nicht zu oft öffnen.

        4x18650 Charger/Powerbank
        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 ;)

      Shipping & Payment

      Shipping

      There are two key factors which will affect the time you receive your items.

      1
      Item processing time
      After confirming your payment, we usually ship products out within 24 business hours. However, sometimes due to large transaction volumes or other order issues, we may require up to 3 working days to process orders. You will receive a notification email as soon as your product(s) have been dispatched.
