2.0 out of 5 stars Improperly wired but hackable, June 20, 2011
This review is from: Griffin Powerjolt Dual Universal USB Micro (Electronics)
Like many others my HTC Evo first saw this charger as a USB charger and would not draw enough power to maintain a charge while GPS navigating and streaming music at the same time.

Following the USB charger spec I cracked open the case and soldered the two middle (USB data) pins together on both sides of the unit.

The disassembly of the case damaged it slightly and this obviously voided my warranty, but the results are as good as one could hope for. In our Nissan Altima the modded version of this adapter was able to positively charge both the Evo under full load as well as an iPad 2 at the same time.

I've posted a photo of the pins to solder for reference for those who are brave and own a soldering iron.

4.0 out of 5 stars Careful - This is not a 2 Amp charger - won't work with Ipad, March 30, 2011
Amazon Verified Purchase( What's this?)
This review is from: Griffin Powerjolt Dual Universal USB Micro (Electronics)
I purchased this looking for a smaller charger and I love Griffin products. The description for this product says that it is "2 A" and can charge a variety of electronic devices which connect to a USB charger. The packaging more clearly describes the charger as having two USB ports which produce 1 A each. It appears that the description is adding the two together which is not helpful. Ipods and Iphones only need 1A or 1 amp chargers while the Ipad needs a 2A or 2 amp charger. Two 1 amp charging ports does not equal one 2 amp charging port.

Other than that - a great product.

5.0 out of 5 stars Better than the item it replaces! Great form factor and plenty of power!, November 18, 2010
This review is from: Griffin Powerjolt Dual Universal USB Micro (Electronics)
I purchased this item to replace what looks like an older (and unsatisfactory) version of this product: Griffin Technology Powerjolt Dual Universal (Black). This new version has many benefits over the old... It does not work it's way out of the power socket like the old version, it is smaller, and it puts out more power (plenty to charge my DroidX which requires 850mA, this puts out 1A per socket).

I have been using it for a couple of months so far, and it's performed flawlessly.
