Specification: Item Type: 16x18650 DIY Power Bank Model: L16 Material: ABS Product Weight: Approx. 220g / 7.8oz Battery Type: 16 x 18650 Battery (not included) Interface: 5V-2.1A Output Port: 2 x USB Input Port: Micro /Type C Scope of Application: Support all models of mobile phones for charging Package List: 1 x Battery Box (Battery Not Included) 1 x Lanyard 1 x Screwdriver 7 x Screw Review: Zum Beleuchten einer Growbox bestellte ich mir jene Powerbank, die mit 12 18650 Akkus betrieben wird. Warum nur 12?! Naja.. Wenn ich wie angegeben 16 Akkus einlegen sollte, fliegt mit das Ding um die Ohren!! Bereits beim Einlegen eines 13ten 18650 brachte eine immense Rauchentwicklung unabhängig, welche Marke ich nutzte. Das geht so nicht und muss dringend nach gebessert werden!! Akku-Sicherheit hat oberste Priorität! Ansonsten brauchte ich über die Powerbank knapp 32 h bis sie annähernd voll waren.. Nicht sonderlich verwunderlich, bei der Masse an mAh. Dennoch würde ich empfehlen ein externes Akkuladegerät zu nutzen, welches mit 2A lädt. Macht das Leben leichter, schon die Akkus unter Umständen und spart Zeit. Dennoch bin ich im Großen und Ganzen Zufrieden! Review: Bonne qualité ## Features - DIY Mobile Power: Large capacity with 16 x 18650 batteries (not included).
