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 ,Raspberry Pi,etc, suitable for factories, trade shows, laboratory [Bottom Line] The Homern 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 Dimension: Voltage: DC 3-9V (error +/- 1%) Current: 0-3A (error: +/- 2%) Maximum support: 5A 5A current (beyond 3A error will be larger in 3%) Resolution : Voltage 10mV current 1mA Full scale drop : ( When measuring current ) 200mV Package Included: 1 X USB tester

Clear readout - very useful
I have tried several of similar meters. I find this one easiest to read and handy with the output on 2 sides.Only wish it had a type C output

Nice easy to read volt amp LED meter .
I'm using mine to check charging rates from solar cells. Put it between charging source and the device to charge to see the connection statistics. Zero is full or not connected.

This does the job!
I had about 14 charger/cord combos that I knew were bad and kept them all because I couldn't tell whether it was the charger or the cord was bad. This showed that all the chargers were good, and I had 13 bad cords. I will never have to buy a new charger ever again in my life. Just cords! Too bad I didn't get one of these years ago! So many unnecessary purchases of chargers!

Serves the Purpose
Seems like the readout is always facing away from you. Maybe make the plug rotatable. Hard to read, needs some backlighting. Other than that, a good tool to have handy.

Ledgible.
I like this for auto use due to legibility and youth. I use a similar device w/o color and smaller digits for more detailed use, which includes resettable-cumulative mah which a battery will accept, to determine capacity of older batteries.
