Motorola P793 Universal USB Portable Power Pack Review

Motorola P793 Universal USB Portable Power Pack Review
We loved the fact that this is a truly universal portable charger working with all brands of phones and gadgets, which use either USB or microUSB to charge. This of course includes recent Motorola phones, but is in no way limited to them – you can juice up your iPhone, BlackBerry, Nokia, Samsung... everything that supports the Universal Serial Bus. 

At the same time, you can plug in another device, so both charge simultaneously – one via the USB port and one with the microUSB cable tucked neatly around the Power Pack's body.

But looks are not the most important thing for a charger – its real capacity is what truly matters. We tested the Motorola Universal Portable Power Pack with one of the most common phones, the iPhone 4, which had its 1420mAh battery running out. One hour of charging brought it up by 35%.

Our next test included a fully drained iPhone 4 which relied solely on the Power Pack's juice. It took nearly two hours for the Power Pack to be drained completely and after that period, the iPhone 4's indicator showed a 67% charge of the battery. This showed some consistency of charging the iPhone at around 33% per hour. Probably not the best of achievements, given the lengthy recharging time of the Power Pack, but for a relatively compact, universal and affordable device we were content with the results. Spec-wise this should translate into five additional hours of talk time on your phone.


For a current price of around $35 on Amazon, you can hardly go wrong with this charger – it's portable, lightweight and its compactly tucked microUSB cable contributes to the pleasing looks. The 1420mAh capacity is by no means impressive, but it suffices to get you through the day, even if your phone has little to no charge. We would abstain from using it to power something bigger like a tablet – we actually tried charging the iPad 2 with it, but the 500mA output current was low as the tablet requires at least two amps. For everything else – the Power Pack delivers.

The battery is the same size as it is for HTC phones because HTC doesn't believe in big batteries. Other brands not so much droid bionic will have a 1920mA battery which will not be enough. Not sure if ill get it.

I assume the micro USB port is for charging the P793, but what is the USB port for? The blue extender is I assume to charge my DROID. How much of my DROID will be charged when the charger is a full capacity. And how much time does it take?Aproximately. With the P793 plugged into the DROID I can continue to use the smartphone as long as I have it plugged in until all of the charge is used up. Right?
Thanks for your help.

Usb is used for any other device you want to charge. You droid will be charged 100% if you have the stock battery in it. You can also use your phone or any device while you're charging.
