        18650er Akku mit USB-Anschluß
        Pros:
        Versandzeit war absolut im Rahmen.
        Artikel entspricht der Beschreibung.
        Benutze die Akkus in einer BLF A6 und einer Convoy S2+ 365nm Nichia UV.
        Dort passen sie rein. Etwas knapp, aber es geht.
        Für mich eine gute Lösung um auf Reisen kein Ladegerät mit nehmen zu müssen.
        Cons:
        Nothing so far.
