Our lives are increasingly dependent upon mobile technology, which makes running out of juice when you’re out and about a huge pain point. Don’t let your low battery get the best of you: use a portable battery pack, and give yourself a charge whenever you need it. With today’s deal from Pocket-lint Deals, you can get the Power Vault for just $30 with free US shipping and $35/£23 with international shipping.

The Power Vault packs a massive 18,000 mAh battery. An iPhone 6 battery is a mere 1,810 mAh, so you should be able to fully charge an iPhone 6 almost ten times one just one charge of the Power Vault. It’s got two USB outlets so you can charge multiple devices at once, and one of the ports charges at 2.1A capacity for tablets.

For such a high capacity charger, it comes in a relatively small and slim aluminum package. It’s also got a nice blue finish that’s pretty easy on the eyes. Best of all, it comes in at an incredibly attractive price. At 72 per cent off the list price, US users can get this unit for $30 with free shipping. And for non-US users, it will only cost an extra $5 for international shipping. That’s a small price to pay to never worry about having a charge on the road.

Whether you’re a mobile device power user or a frequent traveler, tossing the Power Vault in your bag will save you several headaches. You won’t need to be searching for the nearest outlet or charging station - it’ll be right in your pocket.
