## Questions & Answers

**Q: Any way to tell the wattage like the older model?**
A: The new V3 model does not show wattage, but it can be calculated as volts x amps.

**Q: Can this device also calculate and display how much data is being transmitted?**
A: No.  It monitors voltage and amps through it but not data.

**Q: Does the meter log current and voltage data?**
A: If by logging you mean send it to a file to keep a historic record, no. It just shows the current consumed voltage and current, as well as a total consumed current since it was last reset.

**Q: Will this keep a usb powerbank's outputs enabled? i'm powering a low-current, non-usb load, and my powerbank turns itself off...**
A: According to the product description, it has a parasitic drain of about 13mA to run its circuitry.  That should be enough to keep some DC adapters awake.  Not sure if the 13mA rating is with LED on or off, but when the LED auto-shuts off, you can shine a light into the LCD display and see that it's still working with no load.  Long story short, I've noticed that my small smart DC adapters stay energized when the PortaPow is plugged in even with no load (including USB cables) but have to assume that threshold currents would vary depending on the powerbank.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Easy to Use Portable Tester
*by E***N on August 3, 2016*

Purchased the PortaPow Dual USB Power Monitor to test a portable solar panel and some cables that we recently purchased. The first picture shows how the unit was received in a plastic bag. Second picture shows the instruction sheet that is folded and enclosed in the bag. The unit was well packed in a padded shipping envelope and arrived in good shape.The unit worked great and made verifying the output of the 2 USB ports on the solar panel a snap. The third picture shows the device display that was taken indoors and it clearly shows the back lighting in operation. Had concerns about how the display would be in the bright sunshine. The display, even in bright sunshine, was easy to read. The last picture shows the display in bright sunshine. The protective plastic film is still on the display. The instructions tell you to remove it. I wanted to test the unit first so left the protective film on during these pictures. The display is crisp and clean once the film is removed.The unit displays basic voltage, current and a cumulative value that equates to mAh for evaluating battery pack charge capacity. That's all that was needed for the testing we did. The device specifications state there are nine memory positions to store the mAh readings. This could be useful for anyone who wants to track or compare differences between chargers and devices. The instruction sheet clearly states that the backlight will turn off automatically after 5 minutes to save power. This gives a more accurate mAh reading. Simply push the button on the device and the display will turn on again.Did not test the device readings against any laboratory test equipment to verify accuracy of the readings. Our main use is a quick test reading that does not require high accuracy. See no reason to doubt the accuracy claims from the manufacturer. It was very easy to determine the voltage drop of some new "heavy duty" USB cables. We simply swapped individual cables between a fixed charger, the PortaPow and a battery under charge and noted the readings. A very simple test, but we were pleasantly surprised to see how the larger AWG wire used for the USB power leads in the new cables really made if difference in the charging current.The PortaPow has two USB test ports;USB1 and USB2USB1 -- is charge only and blocks all data transfer. This allows you to charge your device from any USB socket without risk of data hacking. The data blocking prevents downloading or reading anything stored on your device through the USB port. This is especially important when you are using any USB port that is shared publicly.USB2 -- passes both data and charge.The unit size was easy to hold when making cable changes during our tests and the light weight (.8 oz) makes it a very portable device. The cost was low enough that we have one in our home computer shop and carry another one for use in the RV when setting up our portable solar panel.This product was not provided as a sample for this review, so none of these comments are influenced in any way by the seller.UPDATE - added a couple of pictures to better show the size of the unit. Also added statement about backlight operation of the display.

### ⭐⭐⭐⭐⭐ works great, and readout features are are surprisingly nice
*by M***N on October 6, 2023*

I'm a sucker for little widgets that give you data about what's happening. I was pleasantly surprised to find that this not only shows you voltage and current, but also has multiple individual memories (9 of them, apparently) that show how much current has transferred to the device being charged in a given session.

### ⭐⭐⭐⭐⭐ A versatile unit
*by L***R on June 10, 2020*

This allows USB charging from public chargers while blocking (or allowing) USB data transfers, depending on which port your device is connected to; a good security feature. There is a power monitor showing how charging is proceeding, with several memories if that's of interest, plus an USB-C port for newer devices. Instructions are sparse and not the best, but the device is quite useful, particularly on travel.
