1. Charger Doctor Digital Multimeter USB Tester Current Voltage Meter Detector Battery Monitor with Dual Outputs for Solar Panel Chargers Cables &Other USB Devices Troubleshooting Tools and Gadgets
Feature
A simple little diagnostic tool.Functions well to monitor battery charging status. Shows volts supplied and amps drawn. Answered a few questions of your own as to why some devices charged better than othersGreat little digital multimeter for testing voltage/amps output and power draw for usb-driven devices. Easy to read, helps identify which chargers put out the most charging current.This does do the trick for trouble shooting
This foolproof usb meter has been a real benefit in sorting apple iPad (original), iPod (original), iPhone (4s), cables and wall warts adapters into how well they are working for each of these apple devices.Are they capable of supplying adequate power
A very handy USB power monitor to have around for checking both Vdc and the current a USB device would draw with re-charging and go to zero when fully charged
Unlike other USB multimeter, which displays voltage and current in alternate mode and you have to wait for the other mode. This device displays both voltage and current simultaneously!
Description
Have you ever meet the problem of suboptimal voltage in cheap power adapters? Or when USB devices don't work, they can be hard to troubleshoot.Here you go to the right place. Our USB load tester can be used to check whether a USB power supply (charger) or battery bank is actually providing the rated output or not.(A lot of cheap chargers will say things like 5V/2A but actually deliver 1A or even just 500mA before the voltage starts dropping, slowing your charge speed.)
Charger Doctor models that cycle between volts and amps. This USB connector shows the volts and amps at the same time, and in a different color.It also has two outputs for both Power and Data
Usable in most circumstances:
USB devices like smartphones, tablets and cellphone, USB batteries, chargers, cables Arduino, Raspberry Pi,etc, suitable for factories, trade shows, laboratory
[Bottom Line]
The Ardess USB meter is closely to those produced by a good multimeter.For most applications, all you need to know is whether your USB port is charging at slow (0.5A), fast (over 1A), or not at all. A precise reading is not really necessary in this case. Therefore we consider this product a good value for your need.
Features:
- The two USB ports can be used for both Power and Data
- Large LED displays shows voltage and current in real time (simultaneously).Numbers are easy to read
- Bright blue and red LED display shows you voltage and amperage in cycle
- Handy device for monitoring the flow of power to an equipment being charged.You can see the amperage drop as the unit being charged fills up
