Just saw the post on engadget as well, looks promising, hopefully it doesn't make the phone to thick, but would be a excellent thing for travelling if nothing else!

Of course it will make the phone too thick, just look at it :eek: !



I thought about getting one, then changed my mind as soon as I looked at the pictures. :mad:

I have a question look at the specifications Powerskin it is 5V, the problem is this is compatible with our European phone with a 3.7 V battery?
It's universal, USB power is ~5V. All batteries in all DHDs say 3.7v remember that all this extra battery is doing is providing power via USB, therefore it needs to be ~5V.

Correct me if I'm wrong anybody. :D

Doesn't seem any thicker than with a Case Mate Pop case. I have one so I'm sure I can live with this.

It needs to be 5V to appear as a charger to the Desire HD. But I see several issues with this:

-The Desire HD will be in constant charge mode until the external battery discharges. Only then the internal battery will start to be used.
It's not good to use a device while charging, this reduces the battery life, so this case will reduce the internal battery life.

-Being 5V means that the case internal 3.7V must be pumped to 5V and then reduces again to 4.2 to charge the battery. Pumps and regulators usually have a 80% efficiency, so 1500 x 0.8 x 0.8 = 960. Expect a battery improvement equivalent to 960 mA, not to 1500mA.


Still it's a great accesory for some situations where you spect to have a great consumption, like hicking with GPS, 3G use while moving, etc. And when the external battery is discharged you can remove the case and have the device full charged with its original size.

You can also turn the case off so it won't charge your phone. Then it doesn't charge the phone constantly and the internal battery life won't reduce that much.

Thanks for that picture :) It does look a bit thicker, but if nothing else its nice to have with you for weekend trips etc when you know you cant charge.

Does it work like a charger in the way that you can turn it off untill your internal battery is almost depleted, then switch it on and charge up the internal one (if you leave the phone idle?) or does it not really charge the internal one, just keep the phone alive on the extra battery?

Anyone tried this yet or has ordered one already? I'm really interested in this, but since I'm only 16-years, I don't have the money to try something out with a chance of not being worth it :).

HTC Desire Dimensions 4.80L X 2.70W X .46H from HTC site.
PowerSkin Dimensions 5.32L X 2.84W X .84H from power-skin.

Yes with powerskin case it is going to be twice as thick (deep)...Length and width are almost the same...

It's a fascinating idea, but - converting inches to cm - that is about 0.8cm more, for a phone that is just about 1cm deep. In fact, the manufacturers do mention 0.8cm as a generic add-on. That's a lot of bulk...

For all-day GPS-intensive stuff I take along a 5000mah power pack that does the job nicely, which you just unplug if you need to make calls etc. Back in the bag, and connect it back up :)

Though I'm sure this powerskin will meet the needs of some people out there.
