Good universal charger
Your regular battery charger won't charge 30T batteries. This works well and gives plenty of information about your batteries' condition.

Pleased. Charger provides insight and rate of charge can be varied.
Charger is good - provides useful information about the health of the battery and state of charge, and allows a level of adjustment. Packaging was slightly damaged - inner plastic packaging was cracked badly. Also looked like the product had previously been removed and cable unravelled.

Good but a special usb power supply is needed
This product is excellent you can set the charge current in 100mA steps up to the maximum, lots of information on the display, Voltage, charge current, battery capacity, charge time etc. But I have two minor niggles, 1, Some AAA wont connect to the -ve terminal if the battery has a flat base. 2, you must have a Q3 (Qualcomm) usb power supply to use the high charge current features.

Good stuff

Great for larger Lithium batteries such as 21700 for torches with useful AA NiMH etc. USBC (USM2).
Early days but good so far. Used it with 21700 batteries which was main reason for buying but also tried some older NiMH AA batteries for a health report and all good. Doesn't seem to fussy on power supply, have a 45W USBC port on my UK Wall Socket in the kitchen and happily quick charged off that, alongside a quick try on higher end Anker charger. Did notice a review when researching this saying it wasn't USBC (which is exactly why I wanted this one). I suspect they received a UM2. This USM2 is USB-C (thankfully).

Uses micro USB
The description does not state what type of sun port this has. Unfortunately it uses Micro USB.

The dogs wotsits!
What a great little charger. I own quite a few torches and some of the batteries are quite old. This charger sorted them all out! I would highly recommend this charger.

Appalling quality!
I ordered this charger to charge up a couple of i Series Nitecore 21700 batteries. On opening the box it looked an excellent charger, well made, and I have read that not many chargers will charge up the i Series Nitecore batteries, also after reading reviews, Nitecore chargers seemed well respected, excellent and reliable chargers. Nitecore do specify this model of charger as been been able to charge the i Series batteries, so I thought what better charger to get to have full compatibility. I connected the USB cable to a power source (one that I can confirm is working, and also I tried the a AC USB wall adapter plug with a different USB device again that I can confirm is working) but absolutely nothing happened. The screen did not light up, it was totally dead. I can confirm that all the cables were fully inserted. I raised the return and ordered a second charger and put it down to that I have received a faulty charger (it does happen I suppose). The second charger came and it was exactly the same as the first, i.e. plugged it into the power source and the charger was dead, the screen did NOT light up. And again confirmed that all the cables were fully inserted, tried to power a different USB device (and again the other USB device I tried worked, so I know 100 percent on both chargers that it was down to the chargers been faulty). I think that there must be a bad batch of these chargers. I am now in the process of returning the second charger, and I will ask around and see if I can find an alternative charger that will charge up the i Series Nitecore batteries. It's certainly put me off ordering a third one, as this should not be needed to be done, on a charger of this price. Hopefully I will find an alternative that actually works out of the box!

Très bon chargeur d’accus à condition d’avoir le bon adaptateur et le bon câble pour la charge rapide

good quality and you can feel it. It does take a long time to charge big batteries.

1. Lieferung und Verpackung Beides direkt über Amazon abgewickelt. Schnell und unkompliziert, Verpackung umweltbewusst und von der Größe her angemessen. Artikelverpackung hatte aber eine ordentliche Delle, der Artikel war aber unbeschädigt und noch versigelt. Ein QR-Code auf der Verpackung dient zur Verifizierung der Echtheit. 2. Kaufgrund Ich habe knapp 2 Jahre ein Efest Slim Gerät zum Laden von IMR Akkus verwendet. Dieses hat nun kurz nach der Garantiezeit den Geist aufgegeben und nicht mehr geladen. Daher der Kauf eines anständigen Gerätes in einer doch deutlich höheren Preisklasse (10 Euro vs 28 Euro). Zudem bietet das NITECORE die Möglichkeit alle anderen Arten von Akkus zu laden und das über ein Micro-USB anschluss bei entsprechendem Ladeadapter (nicht inklusive). 3. Das Nitecore-Ladegerät Verarbeitung TOP, keine Mängel oder scharfe Kanten oder ähnliches. Wie erwartet alles perfekt, die Batteriehalter gleiten butterweich und schnappen nicht zu krass zu beim Entnehmen der Akkus. Ich habe zwei Ladeadapter ausprobiert, einen einfachen 2A Samsung Charger und ein multi-USB Ladeadapter mit Power-Delivery (Nutze ich für ein MacBook), welches Quickchare 3.0 unterstützt. Dieser Ladestandart wird auch vom Nitecore unterstützt und bietet 3A Schnelladung von entsprechenden Akkus. Beide Adapter laufen problemlos entsprechend der Spezifikationen. Das Ladegerät erkennt die Akkus automatisch, der Ladevorgang wird angezeigt und man kann Batterieinfos einsehen. Das Display ist fantastisch und deutlich lesbar. Alles in allem eine solide und qualitativ hochwertige Verarbeitung. Gummifüße auf der Unterseite verhindern ein Verrutschen. Nur die Größe des Ladegerätes ist für mich momentan noch gewöhnungsbedürftig, da ich bisher nur das relativ kleine K2 von Efest verwendet habe. 4. Fazit Ein TOP verarbeitetes und solides Produkt. Otisch sieht es super aus, sehr funktional dank micro-USB Anschluss mit Quick-Charge Schnelladefunktion und dabei Unterstützung für alle gägnigen Akkutypen. Klare Kaufempfehlung und 5 Sterne. NACHTRAG: Nach ca. drei Jahren Benutzung ist die USB Buchse locker. Das Gerät läd zwar, sobald man aber ans Kabel kommt geht das Teil leider aus. Mittlerweile geht gernicht mehr. Wie einige andere schon beschrieben haben, ist hier die Buchse mangelhaft und der Problembär. Am besten man macht das Teil gleich nach Erhalt auf (Keine Siegel o.Ä.!) und verklebt die Buchse ordentlich mit dem PCB. So sollte es zu keinem Totalausfall kommen.

It hasn’t failed me yet and meets stated performance specs, so unless catastrophic happens it’s getting 5 stars.

Hızlı şarj desteği kompakt bir çok pili desteklemesi ve bilgi ekranı. Cihaz çok iyi.
