DROK Electrical Testing Editorial Review
The DROK Electronic Load Test Resistor Module is a handy device for checking the capacity and loading capability of batteries. It has a USB and Type C interface with adjustable Constant current ranging from 0.25A-4A. The device comes with an intelligent temperature control cooling fan. Although it may require some research to use correctly, it is straightforward using google to understand how electronic DC loads are used or utilized in testing batteries. It is perfect for testing battery banks, cell phone chargers and battery packs, and it accurately measures current settings. The device can also be used for testing cables connected to a computer, which is a plus. However, it is only designed to monitor voltage and current and does not have the means to monitor mAh or mWh. The product may malfunction below 4 volts, and the Constant current stops working below 3.5 volts, but a user can design a relay to cut off the load. The device was delivered with a one-page printed instruction sheet, and no manual is available to download. The product itself is from China. The device's quality is excellent, and it is a great value for its price, which is some dollars more than an earlier version. It does come with limited resolution (10ma and 100mv) but is perfect for sorting cables or checking what current a charger can supply.
