ROAM WILD with the ultimate portable charger...Ever wanted a portable charger for your laptop? Well fear not - we've answered your prayers. The powergorilla laptop charger will give you an extra 2-5 hours of power, depending on your laptop's specification, and over 20 hours on various other electronic devices. powergorilla will work with devices up to 24volts - so from your laptop, right the way down to your mobile phone or iPod! Just select which voltage you require; 5v, 8.4v, 9.5, 12v, 16v, 19v or 24v and the LCD screen will indicate which setting has been chosen. Then simply hook up your gadget and away you go! You can even daisy-chain, so whilst the powergorilla is charging your laptop, you can charge the powergorilla from the mains power supply. Powergorilla cannot be charged with any mains charger which is less than 16V. Charging with a mains charger that is less than 16V may cause damage to your powergorilla battery. Powergorilla also has many safety features including output auto-lock, voltage limitation protection, short circuit protection, over charging protection and over heat protection. When used in conjunction with the solargorilla, you'll have a totally portable power station! Plus, the powergorilla features solargorilla auto recognition, which means when you connect the solargorilla, the powergorilla will shut off unnecessary internal circuits to improve charging time by up to 2 hours and the little solar logo in the LCD screen will confirm this!
