Last summer, shortly after it first shipped, I got a Google/Asus Nexus 7. I liked it a lot. It came with a charger and micro-USB cable. The charger puts out 2 amps or 10 watts, and the Nexus 7 charges fast on it. After a week or two, I hooked the cable that came with the Nexus 7 up to my computer, and used another cable the charge the tablet.
It worked fine for a few weeks, then the tablet wouldn’t charge. I swapped in another micro-USB cable, and that fixed things. I tossed the defective cable.
I went to Australia and New Zealand in November. On the flight down, the charger blew the circuit breaker on the AC connection on the airplane. During the trip, the tablet refused to charge unless it was turned off. I coped.
When I got home, it worked fine on my home charger and cable.
Two days ago, it stopped charging again. I swapped out the micro-USB cable for a new one, and that fixed it. Intermittent or broken? I wondered. I swapped in the old cable, and it refused to charge. I threw the old cable away.
What’s going on? I have a theory. Some, maybe most, micro-USB cables aren’t meant to carry 2 amps of current. The conductors are too small. They work for a while, but then they burn out. My advice is to get a micro-USB cable that’s rated for 2 amp service, or to get a cable that’s advertised as being suitable for use with 2 amp chargers; Kindle Fire cables are an example.
I have a similar problem with standard USB cables, Win XP and a Samsun Laser Printer….every two weeks the cable burns out and I have to get another…
What’s up? This is getting expensive…
Are you using two amp cables?
Is the source end of the cable plugged into a computer? I’d be surprised if a computer USB port can supply a lot of current.
I’m sick and tired of burned out chargers and cables.
Micro usb plug, not the cable are rated at 1.8, so the just burn, sometimes you can smell that burn electrical smell.
