This power monitor plugs directly into any USB socket and allows you to connect any USB cable into it for charging or data transfer. It displays on screen the voltage, current and the total amount of current which has been output.
It is also allows you to compare the power of different USB sockets, see how much power each of your devices needs, and study the quirks of USB charging. This is especially useful for solar panels with USB outputs, since it will then allow you to position the panel to maximize the energy it outputs, see what factors affect the panel's performance, and also to see when the output is too low to be worth using the solar panel.
- USB1: Incorporates SmartCharge adaptor as sold separately. This blocks data transfer allowing you to charge from any USB socket without risk of data hacking / viruses, and allows upto 4x faster charging than is normally possible from Computer / Car USB sockets.
- USB2: A normal USB 2.0 socket, allows data transfer and charging.
- 0-4000mA (4.0A), 3-20V Range, Accurate to 0.01A, 0.01V. Uses <13mA for an accurate readout. Fully compatible with Qualcomm Quick Charge 1.0, 2.0, and 3.0.

v3 Works - but looks ugly
Posted by Herbert M. on 13th Nov 2016
I got yesterday the USB Power Monitor V3 and tried on various devices. It works, as already described by others, quite acceptable. But the USB-Monitor looks completely different from the sales pictures. The display orientation is silver, high-gloss. The previous back print and additional information were printed in white on the left frontside. It seems ugly. Inferior looks and haptics. Realistically illustrated in the offer I would not ordered it here. A little bit esthetics must also radiate from a tool.

I bought the PortaPow Power Monitor to let me see how best to orient my solar panel as it is charging various items whilst on expedition. It is functional, easy to read and I would recommend it to anyone that wants a quality means of measuring USB power.
USEFULL LITTLE BUGGER
Posted by Zubair Rana on 25th Mar 2016
I acquired it to use with my Powertraveller Powermonkey extreme's solar panel so that i can detect from which angle solar panel is passing max. power to the battery. Pretty useful little gadget. Does exactly as advertised. Am quite satisfied with it. Shipment is pretty fast also. Received it exactly on the 10th day here in Pakistan.

No turbo charger support?
Posted by Asanka on 7th Jan 2016
It works fine until i try to plug it into my Nexus 6 stock turbo charger-- as soon as it's connected to motorola charger, the screen goes blank and cannot see anything.
Other than that, works OK i guess!
Useful tool works as advertised

Bought this to analyse various cables, chargers, and devices to see what was what. Have thrown out some underperforming cables as a result. Must have gadget.
Must have tool for USB charging
Posted by Kent Oldhøj on 18th Mar 2015
I have a lot of USB powered gadgets, and using this tool saves me time chosing the best combination of charger/cable for each gadget.
Simple to use and portable. I'd recommend it to all my friends, except they prefer to borrow mine. Bastards.
Works, no problems
Posted by Unknown on 21st Feb 2015
Have been using to check power levels of solar charged batteries with USB, low voltage solar panels with USB and the output of a USB step down circuit. Took me a while to realize these things existed, previously been wondering how I could measure all this when only an internet search was needed.
