I spotted this gadget that may be interesting for those who have/use USB battery chargers… This item allows you to know how many amps is drawing a USB device/charger and also shows the voltage of the 5v output when on load…
Only 6.40$…. I was searching and another higher quality ones with LCD display instead of LED display cost +50$ (dont konw its accuracy….)
Thanks, fran! Seems like a useful device for my Soshine SC-F3 and other USB devices. I know from my ammeter the Soshine pulses over 1A during charge but would like to see draw at the USB point rather than measuring in circuit with the cell using a DMM.
It is quite small but for some devices it can get in the way of other ports and plugs. There are small clips which are quite fragile but you can remove the case if you are careful:
Here you can see it just fits with the case removed:
With a device connected it alternates between showing current draw for approx 7 seconds then voltage for 3 seconds.
