Last call for suggestion on a USB meter, 0.001 A and maybe a cable test

Ebay has a 10% ebate going through tonight, so I want to buy something while its active. In addition to the 1ma accuracy, actually just show current below 10ma even if its not great accuracy overall, I see some will test USB cables for resistance and type, which sounds good to have. I’ll be searching on my own, but actual suggestions on units to buy that sell on ebay appreciated. Thanks.

USB cable quality / resistance measurement?

I have a number of USB cables and I notice that different combinations of cables and adapters/power banks result in different charge rates. For instance, a short cable (eg. 0.5m) usually can output a high current (eg. 1.74A) when charging a device (eg. Galaxy S5) , whether the cable was connected to the wall outlet (charger) or power bank. But a longer cable (1.0m) can output a high current (eg. 1.74A) when connected with a wall outlet charger, but will decrease somewhat (eg. 1.15-1.55A) wh…

Good source of quality Micro-USB cables?

Around the house I have a lot of devices that are charged or powered from Micro-USB, this caused me many headaches because so many cables are of low quality: low gauge and poor plating are the usual suspects. So I am planning to throw ALL away to the electronics recycle bin, and buy several (at least a dozen) high quality cables. Can any of you recommend MicroUSB cables (charge and data) quality at a good price. Please do NOT provide links to shops or sellers in the US as import and transport r…

Good USB-Cables??

I have been using Keweisi and such devices for a while now. I don´t know if it is the cable itself or how the devices (charger, phone) “see” the cable and its resistances in the middle but: There are huuge differences in how much current I get on my devices with different cables… I don´t even need meters to notice: With good cables the chargers heat up so much more, that I can just feel the difference. So: I need recommendations for a bunch of good quality USB -> Micro USB + USB -> USB Type…

Guide: how to test USB power source and USB cable without any special hardware.

All you need is any iOS or Android device (phone, tablet, etc.). Install one of these free apps: Battery Life (for iOS) or Current Monitor (for Android). Now when you plug in your device to charge, you can monitor charging current, just like you would with a special “USB Current detector” device: [image] [image] If you’ve never done this before, go over all your numerous USB cables one after another plugging them into the same (preferably high quality) power supply and watch the current dra…
