DollaTek Electronic Load Tester USB Load Resistor Module Trigger QC2.0 QC3.0 35W 0.25-5A HD35 Discharge Instelbare constante stroom Intelligente temperatuurregeling met koelventilator

You get what you pay for since this is the more premium one. virtually 0 problems however i find that the fan could kick in a bit quicker since it is very very hot to the touch when picking it up just before the fans kick in.

Sehr genaue und einstellbare Last. Einziges Manko: Die nicht vorhandene deutsche Anleitung. Einige Rezensenten haben in den Kommentaren aber eine "Bedien-Checkliste" erstellt. Habe zuerst den Trigger-Taster an der Außenkante vorne mittig an der Platine gar nicht entdeckt. Es gibt insgesamt also 3 Taster (Set, OK und Trigger). Obwohl der Lüfter temperaturabhängig anspringt bleibt der Laststrom fast bis auf ein Milliampere konstant wie eingestellt. Bei annähernd 30 Watt Last wird der Kühlkörper aber schon sehr heiß. Dauerbetrieb bei dieser Leistungsstufe könnte problematisch werden. Für die meisten Testanwendungen reichen aber 1,5 Ampere und knapp unter 10 Watt wohl aus. Durch die Triggertaste können auch verschiedene Ladeprotokolle (sofern bei der Quelle vorhanden) wie z.B. QC2.0, QC 3.0 oder AFC bzw. FC mit höheren Spannungen wie 5.0 Volt aktiviert werden. Alles in allem eine sehr genaue und einstellbare USB-Last bis max. 3 Ampere.

Es perfecto!

Sono rimasto molto contento di questo carico elettronico, è facile da utilizzare e sembrerebbe anche ben costruito. Lo utilizzo spesso per testare alimentatori o cavi e fin'ora non ha dato mai problemi. Le istruzioni sono un pò complicate, ma alla fine ci si arriva a capire come funziona e risulta tutto molto semplice. Ottima la protezione da sovracorrente per evitare di superare la massima energia dissipabile dal dissipatore e ventola. Perfetto!

For some reason I chose this one over the Utronics load tester which is very similar but features a real knob and a display screen that presents more information to the user. I think the Utronics is rated to 25W and that's why I chose this 35W model. Definitely choose user interface options over power when dealing with stuff like this.I ordered this a while ago and immediately sent it back so I don't even remember instructions being included. There was a QR code and I remember translating those Chinese instructions but that doesn't get you very far. I have a lot of experience with power electronics and it took me a few days to really grasp how to work this thing. The display was hard to read and the lack of terminal block for wires was a disappointment.The biggest reason why I returned it was because the potentiometer was borderline unusable. It was very finnicky about how hard I turned it and I even struggled with precision turns. I could tell that it was something I would dread using and compared to the interface on my FNB48 it was a joke. I wanted a load tester that matched what I had on the USB tester/trigger side of the equation.I ended up going the Atorch route and getting their 65W (35W continuous) load tester with a UD18 mounted on top. A great combination but I still find Atorch to not have the best interface but it is definitely usable.
