This is superior in every aspect notably usb type a lead is built in meaning you neednt piggyback display is much finer with two lines of data has a milliamp charge counter which you can use to measure the true capacity of a powerbank or battery within a reasonable accuracy draws a miniscule current in itselfi received a discount on the full price probably more than what you would pay if you had it shipped straight from china

This is a really useful little gadget and the loss of one star is only down to the fact that it is supplied completely without instructions

The device receiving the power plugs into the fullsized usb socket

There are also no instructions but for basic currentvoltage testing none are really required

The device does hold memories of 10 separate measurements and the button on the device can be used to scroll through them

I doubt many users will use this feature
