The powergorilla in the press

You won't find many mains sockets during a photography expedition, so how will you review your shots? Stocking up on batteries is one solution, but that's not possible with the MacBook Air or 17in MacBook Pro, whose batteries are sealed inside the case. The powergorilla external battery pack adds an extra two to five hours of life. It also features a USB port, so you can recharge your iPhone. |

"If you're a technophile who always ends up needing a separate bag for all your chargers then this will be worthy investment - even if you do have to invest a little extra cash to make your MacBook work harder." |

"This 631g A5-sized battery pack is designed to recharge your laptop on the move. A series of power 'tips' are compatible with most laptop brands, but check the website to see if yours is supported. There's also a USB port and tip pack for charging other devices.
A button lets you select 5V, 16V, 19V and 24V output voltages. The voltage affects the mAh rating of the battery and therefore the extra battery life your laptop can get from it. Running at 16V on a Sony VAIO VGN-G11VN, we managed to double the battery life from seven hours and five minutes to 14 hours and 14 minutes. If you need extra battery life on your laptop, this is an easy way to provide it." |
