In its travels, portable power system manufacturer Powertraveller says that it's come across the question many times: "Can you make a battery with enough charge to run a laptop all day?" It now has an answer. The silverback-gorilla is its beefiest portable power pack yet.
Small portable chargers like Powertraveller's solarmonkey adventurer are good for juicing small gadgets, but if you really plan to suck down power, the 60,000-mAh, lithium-polymer-based silverback-gorilla can keep your laptop running for up to 14 hours. The uninterruptible power supply (UPS) is designed to travel with you and provide a back-up in case of power outage or disruption, something that could be useful if your travels take you to places with unreliable power infrastructure.
The silverback is similar to Powertraveller's powergorilla, but it is more powerful, and adds a 240-volt AC output socket. You can easily switch between numerous DC output voltages and charge devices from your laptop down to your iPod. There are two USB outputs and multiple devices can be charged at once.
The LCD display lets you know which of the selectable output voltages has been chosen, as well as the remaining battery life and input status of the device. The available alarm feature lets you know if electricity into the silverback is cut-off but will continue to charge the device. An output auto-off cuts power after two minutes without a load.
The silverback-gorilla has an aluminum housing with rubber shock-resistant strips. It measures 9.6 x 8 x 1.3 inches (243 x 203 x 33 mm) and weighs 5.5 pounds (2.5 kg).
A Powertraveller rep told us that the silverback-gorilla will launch this summer for approximately £300 (US$460).
