Anyone who's ever had the battery die in their cell phone, MP3 player, camera, or other electronic device knows what a pain it can be (and that it always seems to happen at the most innoportune moment). iSound's Portable Power Max is perfect for avoiding these annoyances: an ultra-portable backup battery that will charge multiple devices at once, without the need for an AC outlet or multiple backup batteries.
A 16,000 mAh Lithium-Polymer battery provides up to 480 hours of power, so you can talk more, listen to more music, and view videos longer. That's enough juice to charge an iPad twice, or charge an iPhone 4 eleven times.
The Portable Power Max will charge any device with a maximum current requirement of 2.4 A (as an example, the iPhone requires a maximum of 1 A). It's perfect for the iPad, iPod, iPhone, and other common portable devices.
Don't need the Max model? An 8,000 mAh Portable Power is also available, for 240 hours of charging power.
The Portable Power Max's battery takes about 7-9 hours to receive a full charge. LED status indicators let you know how much charge power is remaining--when all four blue LEDs are on, you've got a full battery, and are ready to go! Charging times for connected devices depend on individual specifications.
The Portable Power features five USB ports, allowing you to charge five USB-charged devices at once. The included USB to micro USB cable is actually a splitter, which brings the grand total up to six.
Use the Portable Power to charge several devices overnight from a single AC outlet--perfect for anyone who travels with a bag/pocket full of gadgets, or for family vacations, charging everyone’s electronics at the same time.
A handy travel bag is also included, for easy transport.
Connect your devices in the dark with this handy built-in flashlight--find cords and ports with ease.
Conveniently re-charge the Portable Power Max with the included AC adapter.
Some BlackBerry models require use of the enclosed BlackBerry adapter in order to charge properly.

The battery pack still seems to work, but I no longer can tell the amount of charge remaining in the battery pack.
So I emailed customer support of the company that made or marketed this product, at the email address it provided on the warranty card.
When you're traveling you can leave it plugged in at your hotel room and with multiple USB adapters you can charge everything at once.
The charger makes a high pitch constant electric beeping noise when plugged in. At first I thought it was an isolated issue. Read morePublished 7 days ago by Carl,
From one charge I charged my iPhone 5s full for three times. Good result. It is almost perfect but plastic is cheap to the touch and very markable.Published 8 days ago by Gray Wind
Similar to other reviewers, I found this to be amazing in the first few months. Yet at the 7th month of ownership and limited use, it just stopped working. Read morePublished 13 days ago by Valerie Pierce
