Customer Reviews
After a camping trip where our battery packs died on day 2 I vowed to never be with out battery power again. I have about 40 18650 batteries I have salvaged from laptops and power tools that are in good working order so I bought this unit. I tested this out by charging my Galaxy S9. It would seem a full charge takes a little less than 2 batteries. This is fabulous as I can carry about 30 batteries with me in a storage case when we go camping. When I get home after camping I can use the many chargers (and this unit) to charge up all the batteries again for the next trip. I am also looking into a Solar battery pack, but for the time being this will have to due until I can afford something substantial. I would highly recommend this for anyone looking to utilize 18650 batteries as a power source for charging items via USB. I have been carrying this around with me in my back pack since I got it and it has gotten me out of a jam a few times when I have been away from a power source for a whole day.It’s great to be able to charge 4 batteries at once and the cover keeps the batteries from popping out.I did find that plugging in the micro USB was more difficult than it should be.Produkte von Nitecore sind normalerweiße sehr hochwertig. Li-Ionen, Ladegeräte und Taschenlampen. Aber leider nicht diese Powerbank.Das Problem: In meinem Fall darf ich meine 18650 Akkus nicht im Powerbank belassen, da sich sich mit der Zeit ohne Gebrauch sich entladen. Anfänglich 4,2 Volt pro Zelle (da wird das Laden der Akkus beendet) fällt die Spannung in einer Woche auf 3,9 Volt (getestet mit mehrere 18650 Zellen).Nach genauerem Durchmessen der Powerbank ist mir dann leider aufgefallen, obwohl dieser abgeschaltet war dennoch ne Restspannung an denn USB Buchsen anliegen. Ein eingeschalteten Zustand liegen 5,1 Volt an, im abgeschalteten Zustand 0,5 Volt. Klinkt zwar nicht viel, dennoch reich es das mit der Zeit die Akkus sich langsam entleeren. Bei einem intakten Powerbank darf keine Spannung in ausgeschaltetem Zustand an der Ports anliegen. Und wer jeder sich mit Li-Ionen beschäftig, weiß das dies erst recht ein absolutes No-Go ist.Zitat Produktbeschreibung: Der Nitecore F4 ist in der Lage tiefentladene Li-Ion Akkus mit Schutzschaltung zu reaktivieren.Man braucht auch diese Funktion, wenn man die Zellen im Powerbank belässt (-;Ob es sich jetzt bei mir anbei um ein Einzelfall handelt, kann ich leider nicht beurteilen.Compact, works well, plenty of data on the display. Others have reported some parasitic drain, but I still need to test that.The annoyance, when using as a power bank: as the attached device approaches full, the charge current drops and the F4's atuo power save stops the charging a bit before it is complete.Very handy charging very good and nice powerbank with 2 USB OUTPUTS.super charging mod.good clear lcd.very good.value for money
