When your smartphone battery is nearly dead just minutes before an important conference call, what do you do?
Before now, your only option was to get your hands on a charger and search every skirting board for a power outlet to drain as much juice as possible from in a short amount of time.
However, a new device will now let you fully charge your phone in just 15 minutes. Called the Ultrapak battery pack, it is a portable battery pack that breaks the constraining umbilical cord of a power socket cable.
Now these aren't new, power packs have been around for a while. The difference with the Ultrapak is that it absorbs power around eight times faster than its rivals. In just fifteen minutes it will hold enough juice to fully charge a normal smartphone, meaning as an emergency resort it's the perfect product.
If you've got just fifteen minutes before taking an important call, getting on a plane or leaving the office, plugging the ultrapack in to charge will mean that by the time you need to leave you'll have a whole cell of battery ready to travel with you.
The Ultrapak comes in two sizes. The larger of the two sells for $100 (around £60) and is about the size of a man's wallet. It can charge a phone around four times over or a tablet once. The smaller one is $60 (around £35) and carries about a third of the battery capacity.
