    Nutze sehr viele 16850 Akkus aus Laptops in Single Powebank Cases (siehe Foto) .....hier kann ich jetzt schnell sehen nach wieviel Zeit die Spannung zusammenbricht. Über den Poti kann man die Last erhöhen oder absenken...... Der Lüfter springt dynamisch an, wenn es zu heiss wird :-) Denke ich werde noch weitere kaufen für diesen Preis.

    მივიღე ჩინური ფოსტის რეგისტრირებული გზავნილით 15 დღეში, ძასლიან საზიზღად იყო შეფუთული, არაფერში არც იდო, არც გახვეული არ იყო, უბრალოდ ცელოფანში ეგდო! თითქმის დაუზიანებლად, პოტენციომეტრი იყო

    Leuk tooltje. Net getest en werkt goed. Meerslagen potmeter dus je bent wel een tijdje aan het draaien om gewenste belasting in te stellen. Verpakking was wel heel dun, alleen een zakje zonder bubbeltjes folie als bescherming. Gelukkig uitstekende potmeter niet gekneusd en tool werkt.

    It works as expected. Simple to use and made of high quality components. With this device Now I can check how efficient the USB power source is. Highly recommended! :)

    Delivered via Thailand, took exactly 4 weeks to Germany. Potentiometer/resistor was bend but was able to bend it back to original position. Fan is very silent. PCB looks good, solid work.Thanks!

    Can be very finely adjusted to the "load". In connection with the "RUIDENG UM24 / UM24C USB 2.0 Color LCD Display Tester", you can test very nicely the USB power supplies or power bank.

    簡易電子負荷。 長時間だとやはり高温になるが想定内。 0mAにはなりません。

    Do it job. Works ok. Cons: there is no easy way to check the load before connecting

    A very useful fan with an adjustable value for power consumption to test, such as powerbank. Thank you Banggood!
