The Powerpack’s 4000 mAh battery is much similar to any tablet and much more then any smartphone in the market . We tried to charge several devices using the Energizer XP 4001 and nonetheless the device continued to impress.
After Charging the Energizer XP 4001 to its optimal level, we started off with the iPod Touch 4th Generation. The Apple iPod Touch was completely drained when we plugged it into the USB connection for Phones and Energizer was able to Charge the device up to 100 % in about 2 hours. The time taken by Energizer was almost same as the A/C Adapter of the iPod Touch. Without recharging, the next Device plugged in was Samsung Galaxy S2. Powered by a 1650 mAh. battery, the charging started when the device was dead. In 2 hours, Energizer was able to charge it to 100% power. This time, a bit slower then the A/C Adapter but nonetheless useful. The last in line was Nokia E63 with its 1500 mAh. The device was at 50% charging and Energizer was able to charge it up to 90% power when the Energizer finally drained out.
We also tried to charge a Chinese Made Momo7 tablet with a battery of 4000 mAh. from scratch and Energizer took its battery to 70% before charging out.


Energizer XP 4001From our experience of the Energizer XP 4001, we found it to be a very handy gadget. We were able to charge an iPod Touch and a High End Smartphone completely in one charging of the Energizer and it still had something left.
Although it doesn't exactly charge upto its full rating i.e. 4000 mAh., it still gives out considerable power. We can attribute the ‘less then the power rating’ charge to the start up power required for the devices and old smartphone batteries that extract more power.
The connections are all very sturdy and with various tips, the charging is easy to start. The build quality is exceptional and the the USB ports provide proper connectivity but the tip and smartphone connections were not that reliable.
We recommend the Energizer XP 4001 for users who carry around smartphones and Bluetooth devices. For tablet users, Energizer XP 4001 may not be as effective as for smartphones but it can still give you a lifeline if everything goes black.
