User Reviews about Duracell Powersource Mobile 100

Some people don't know the details about power supplies like this. This one requires a long answer.

The PowerSource will provide about 45 Watt Hours. It has a limit of 60 watts from the battery and 80 watts from the 12 volt input. It has a 100 Watt surge limit for a short time.

Translation: the run time depends on your computer and the existing charge level when you plug it in to the PowerSource.

If your laptop batteries are run down, the PowerSource probably will NOT operate it.
If you remove the batteries it may work. It may also work to charge with the laptop off.
If you run it with the 12 volt input it may operate your laptop.

The reason for this is; your laptop uses twice as much power to run if it charges the batteries at the same time.

It will work, if you plug the laptop into the PowerSource before you run down the batteries.

I tested my HP dual core laptop watching movies over the WIFI link. It ran 1 hour and 35 minutes on the PowerSource then 2 and a half hour on its own batteries. Same test, next day, same results.

This would be 4 hours on an airline flight. It will power a Zune or IPod for a long time.
The more powerful the laptop, the shorter the battery life. Your mileage may vary.

It includes a special plug that work on some airlines power jacks.

Many smart phones use a specially wired charger to charge from the wall and will only charge from a computer IF the computer has a data connection to the smart phone. A different USB cable will not help, unless it is wired special. A cheat that works on some Smart Phones is to plug it in then reboot the smart phone.

I recommend it.
-- It works.

This will not run a laptop for very long. For items with low current draw (what I purchased it to use with) it works great and has excellent battery life. It also has convenient USB ports which are great for charging iPhones and other items with USB chargers. -- Duracell Powersource

This item had already been opened and appeared used when I received it, and it was stamped with a manufacturing date of Nov 2006 (over three years ago!). But it was still partially charged, so I now think it was opened at the factory and charged, then resealed with staples.

I tested it and found that it takes about 4 hours to charge with AC household power. I haven't yet tried charging it or using it as an inverter in my car.

It will light a 13 watt CFL light bulb for 3 to 4 hours. That seems reasonable for how small this unit is, especially considering that the inverter is built in. My other powerpack will light this bulb for many more hours, but it is far larger and heavier (about 20 pounds).

If you're looking for a fairly small and light rechargable battery which will charge electronics like cell phones via USB and also provide light duty AC power for lights and powering netbooks, this is a good option. -- Reasonable performance for its size
