Whether it’s because your smartphone charges too slowly or you’re not sure if a USB port on your PC is working properly, you may need to measure the voltage on your USB ports. So, next we are going to list the best USB voltage and current meters on the market, not only so you can check if the USB port works well, but also so you can calculate the consumption of your devices.
There are many USB multimeters on the market, but in this list we are going to tell you which are in our opinion the best, both for their functionality and for their price.
AMANKA USB Multimeter
This is probably the simplest and most complete multimeter. It allows you to measure the voltage and current intensity of a USB port, and also automatically calculates its consumption and tells you the temperature, all with a very simple interface that simply consists of connecting this multimeter directly to the USB in which we want to measure, and to this the device. It also has a button that allows us to switch between different ways of viewing data on its color LCD screen.
KCX17 USB Digital Multimeter
This other version has a similar operation to the previous one but it can be more comfortable since the USB connector has a small cable for greater comfort. On its monochrome LCD screen it will show us information on the voltage, the amperage and it is also capable of detecting the battery charge of the USB device that we have connected to it, something very useful if you want to check why your mobile charges too slowly.
USB multimeter with Bluetooth
In this case, the multimeter gives us information about the voltage, current and battery charge, as well as the temperature. It allows to work autonomously to check, for example, the charging capacity of a portable battery by simply connecting it to it, but it also has USB Type-A (normal), USB-C and micro USB outputs to connect any type of device to him and thus measure his parameters.
In addition, it has the particularity of having Bluetooth, and through an application for smartphones we can even see curves of voltage and current intensity.
DollaTek USB Multimeter
This multimeter is quite similar to the first one that we have shown you. On its color screen we can see amperage, current intensity, load, temperature and consumption on a color LCD screen, all in the size of a pen drive. It has, like the first, a USB Type-A male connector to connect to the PC’s USB port (for example), and a USB Type-A female port to plug in the device of your choice.
Syfinee multi-connector multimeter
Finally, we have this other multimeter in a cross format that has the particularity of having both standard Type-A and USB-C USB ports for the most modern devices. It measures the voltage, current intensity, temperature, resistance, load and consumption of the USB devices that we connect to it, so we will have very complete information on all the electrical parameters of the USB devices that we connect to it.
