I have bought dozens of the DROK USB 2.0 Charger Detector Multimeter for testing many USB devices in production and prototyping. I have also bought many of the DROK® DC 3-21V Load Battery Tester, 35W 3A Portable USB Monitor, Intelligent Constant Current Electric Discharge.
Unfortunately the Load Tester always needs the Multimeter attached to be useful.
Why don’t you guys build the mulitmeter into the Battery Load so I only have one board?
You can include the heat sink temperature in the data displayed.
A very nice addition would be to show the advertised mode and power available from the power source and presented on the D+/D- lines. 500mA/1A/2.1Amp/2.4A (QC 2.0)
An OLED display would be best for less power and more information available like some of your other products.
