Waze forum

For anyone looking for a high amperage USB charger, check out It's only $10+shipping and at 3A, should be able to fully compete with charging and running Waze at the same time.

Sure, but add an iPad in there and to charge it at full speed requires 2.1A...

Not cheap and definitely over-kill most of the time but it can charge 2 iPads simultaneously if needed.

I was looking for a 4A car charger, but they are pretty rare. Thanks for the link!

I'm using this one.

I can run waze AND charge my phone running at 2A's or less on all the android devices I have had.

The one i presently use should be able to charge an ipad and an iphone, but when I try to charge my Galaxy S3 LTE in it with an iphone it shuts off after a while. And gets rather uncomfortable to touch and hold out of the socket :/

Al, the car charger looks good! Ordered it today! Mahalo!

Has anyone tested any of these with an iPad(3) running Waze AND at less then say 50% charge?

My experience is that every adapter I have tried fails. One would actually overheat and shutdown while using it.

Another question is, do any of them offer their stated higher output at a single USB port or are they independent and splitting the stated total output between ports? (See example of this issue at the URL that I added to jimstars' post above.)

And talk about overkill, I am currently using a Duracell 175W power inverter that has a 2.1A USB port. It was purchased to run my laptop, but the single USB port will keep Waze running on my iPad(3) AND charge it at the same time.

The specs do not indicate the power availability in wattage for the USB port.

Interestingly, an older model of Duracell inverter failed to run my laptop, when the engine was not running. I attribute this to the slightly lower voltage output from the 12V jack, which must have prevented the regulation circuit from performing properly with the higher load of the laptop.

And to be clear, all those other 2.1A adapters (similar to the one mentioned here by others) all worked great on my iPad2.

So if anyone else is using a iPad(3) with Waze, please report your findings! (I think I have discussed this elsewhere too.)

Alan,

Likewise I chose this one also from Amazon .. a little more expensive and a little more power ..

Note that it states that the 3.1 output is NOT available for the iPad.

Nice one, indeed. Unfortunately Amazon does not ship this to my country.
