As great as the Wii U is, the one thing that bugs many owners is the terrible battery life of the GamePad controller. We've lost count of the number of times we've had to play with it connected to the wall charger because we forgot to top-up the battery after the previous day's session.
Thankfully, peripheral manufacturer Nyko has created a solution in the form of the Power Pak - an enhanced battery pack for the GamePad. It offers three times the staying power of the official power cell, but is the same size - which means it fits effortlessly into the existing battery bay. You don't even have to use a special cable to charge it up.
Here's the official line from Nyko:
Keep your Wii U GamePad charged and ready for action with the Power Pak™ from Nyko Technologies®. The Power Pak is a rechargeable Lithium Polymer battery designed exclusively for the GamePad and the rigorous demands of gamers. The triple capacity battery provides up to 3x the playtime on a single charge, and seamlessly replaces the existing GamePad battery for a sleek and seamless upgrade, ideal for marathon gaming sessions. The Power Pak charges using the stock AC Adaptor or Charging Cradle included with the Wii U, as well as Nyko’s charging solutions for the GamePad. The Power Pak is the ideal solution for powering your GamePad allowing you to play longer with no change to the appearance of the controller. A mini screwdriver is included with each PowerPak, no additional tools are needed to install the battery.
For just $24.99, that's a pretty good investment. There's no word on whether or not this is going to be sold outside of North America, but we'd imagine that other alternatives will appear - especially as the GamePad's stamina is a pressing concern for many players.
