I am really distressed by this video. Dude reviews multiple USB cables and finds they lose between 10% to 33% of the power they transmit to resistance.

Where in the video did he even charge a USB device? Never. He simply calculates and compares wiring losses at 5V 2A.

Who is to say that those cables make a 10-30% decrease is the device's actual charging speed?

Good work comparing power losses, but fails horribly at demonstrating real-world implications.

look who doesn't understand the simple physics behind charging a device

breaking news

china shit is shit

next water is wet and sun is hot

This is really bad when you consider that many peripherals need 2 USB connections just to get the 1A they're supposed to from generic PCs.

>>56207082

Comparing the electricity going in one end, and coming out the other end doesn't compare real world scenarios?

5V at 2A is pretty standard for a USB device on charge, if a cable is losing up to 33% of that power once it gets to the device, that's bad.
Really bad.

That's why a lot of >2A phone chargers are 5.25V now, to account for some voltage drop in the cable.

5.3V actually; just checked the print on mine.

Sorry but you sir, are dumb as FUCK.

Leave.
