If you're a regular traveller, then this multi-purpose charger is a great idea.
The powerbrick isn't the smallest we've seen, but with a voltage meter on the side, you can easily set it to the power required.
There are a variety of connections, so you can source power either from the mains, a plane seat or using the cigarette lighter connector in your car.
With a host of plugs covering all the major laptop brands, we're sure your machine will be covered. However, we suggest checking with the Trust website prior to purchase as to whether your particular laptop is covered.
This powerbrick will easily replace your current one, with the added benefit of being able to power a variety of devices.
