I ran into this by accident on amazon. I have something similar but cost much more. Just thought I would share…
GHI used to make something similar on their Outrageous Circuits site called the USB Powermate. I don’t think you can get them anywhere now, though.
I have something similar from Adafruit.
Sadly the one VersaModule linked to is “not available to ship to Jakarta”
AliExpress for the win… http://www.aliexpress.com/item/2016-Newest-LCD-USB-Charger-Capacity-Current-Voltage-Tester-Meter-For-Cell-Phone-Power-Bank/32623928144.html?spm=2114.01010208.3.1.yPuzN0&ws_ab_test=searchweb201556_0,searchweb201602_3_10037_10017_405_404_10033_10032_10040,searchweb201603_11&btsid=41aa633c-9de8-45c1-b1fe-915cf945aefb
Nice one Niels. I’ve just order 2 of them. I like Aliexpress as they use an e-scrow type service which means the seller doesn’t get paid until you say you received the goods.
I received mind yesterday and apart from the fact it could do with 3 decimal places on the AMPS it works great.
At first I thought, damn it’s upside down on the desktop connectors but then I spotted that it works either way around. They have a thin PCB with connections on both sides. Clever.
