Followup -
I finally got my USB tester and 3 USB cables off Amazon:
- Aotnex 26ft Power Extension ROUND
- SIOCEN 16.4FT USB Power Extension ROUND
- LITGAS - 26FT Power Extension Cable FLAT
I assembled the stuff with a
Ravpower 3-Port USB Wall Charger---->The cable—>micro-female-to-USB-A adapter---->tester-----> a 6 inch USB-A extension----->V2
So the tester would be at the end of the tested cable.
Results were:
- The Aotnex delivered 4.7 V/0.3A to V2
- The SIOCEN delivered 4.98V/0.28A to V2 (remember, only 16 foot)
- The LITGAS delivered 4.88V/0.29A to V2
/edit
The standard length Wyze cable delivered 5.04V and 0.28A
