replacement for my lost usb charger
« on: October 13, 2012, 04:09:48 PM »
Hi,
Can anyone tell me if there is a tested, alternate usb charger to replace my lost unit. Any help would be appreciated. Thanks
Wayne

The main difference with the charger for the Nexus 7 is the current. Typical chargers for most phones provide 5V @ 750mA. The charger for the N7 provides 5V @ 2A. You can use other cords, but the AC adapter is the biggest factor. The cord might even be different too. Standard USB 2.0 connectors are only rated @ 1.5A

Thanks for the reply. I was able to charge the nex7 with a generic usb to micro_b usb sync/data cable from The Source. Seemed to have worked fine but took 16 hrs to complete. I'm wondering if there is any loss of capability without the original charger unit besides a faster charge. There has to a 5v/2a usable usb charger out there somewhere to replace mine - still looking...
regards
Wayne

I've charged mine with a 500mA notebook USB port, a 1A external battery pack and the supplied 2A ac charger. :-)

All seen to work fine unlike my Thinkpad Tablet.

You are correct.  The only drawback of the lower current supplied is the charge time. 

After looking into power supplies, I was reminded of the power consumption of devices with fruity names. Take a look at the power supplies intended for use with the devices that will not be mentioned here.  The USB AC/DC adapters for those devices after the 3rg gen should supply the current you require, and be quite readily available.

Hi,
Many thanks again for your sage observations. I found a forum page at xda developers that offers some names of chargers that might work with the Nexus 7:

http://forum.xda-developers.com/showthread.php?t=1801581

My 1st tablet and it is amazing - still haven't quite got a handle on it yet - for instance, can you boot this thing without a wireless isp - or can you actually boot it offline? Seems a pity if not as I primarily wanted to use this with a gopro and their new android app.

Hello,

I can confirm that this charger works great for the Nexus 7. It charges it fully in about 2 hours. Check on Amazon for:

http://www.amazon.com/CrazyOnDigital-Charger-Google-Nexus-Black/dp/B008FF8360/ref=sr_1_3?s=pc&ie=UTF8&qid=1350947689&sr=1-3&keywords=google+nexus+7+accessories

It is affordable and definitely works. I have a couple of them now.

The issue is the amperage. The Nexus 7 requires a higher amperage than many other devices, thus the issue with charging accessories.

I don't know what country you are in but you can buy the "official" charger at Fry's brick and mortar stores. I'm sure google and amazon have them also. As already stated you really want a charger with a 2 amp output. I carry a one amp charger with me for coffee houses which pretty much just keeps the device from draining the battery while I'm using it.

If you opt for a non-OEM charger with 2 USB ports, select the "NA"  (Not Apple) port for the best charging results.
