Opo has higher power requirements. You may need a cable with a 24AWG or better rating (lower allows more current).

Does it work with the stock cable?

My OPO works with any cable, though time to charge is the best on stock cable. But my friend's OPO doesn't charge at all. Even on stock cable.

Unable to make sense of it at all. I may sound like a simpleton, but maybe there is some checkbox I ticked somewhere which is preventing this? UGH! :P

The phone will work with any cable. Worst-case the cable's resistance and diameter will reduce the maximum charging current significantly but it always will charge the phone.

It's because the laptop isn't putting out enough current. It must be at least 2a to charge properly.

No USB port has that much current except maybe for highly specialized ones. USB2 is rated on 0.5Amp, USB3 on 0.9
Of course the phone will take significantly longer to charge or may even discharge when used while plugged in.

I can say "me too". My one also didn't charge from powered off PC while Nexus 5 plugged in the same PC with same cable charges fine.
When PC is powered on, One charges intermittently. I.e. I plug it in, it charges for some time and then stops. "OS monitor" shows "discharging [USB power]" state.
Any thoughts?

Plug Cannot charge OnePlusOne via USB
I have the same problem.
The problem seems to have started AFTER upgrading O/S to Cyanogen 12.0.
Cannot charge via USB either from my note PC or Mobile BatteryPak (1.7a).
Above comment that 2a power is required is surprising, as I thought 1a is standard. Maybe there is some Cyanogen bug here?
I found in some Forum to make of SETTINGS - STORAGE - USB COMPUTER CONNECTION, but I do have this setting, and still cannot charge the computer.

In the USB 1.0 and 2.0 specs, a standard downstream port is capable of delivering up to 500mA (0.5A)

It will charge very slowly but will charge faster if the device is off. If you're using it while it's charging it's like filling a bucket up with water that's got a hole in the bottom. It fills up. But slower than it would if there was no hole.
As for the battery pack I have a 2.0a EE Battery pack and it works fine so it might be related to the analogy above.
