I’ve been hanging out with a Proporta Universal Charger for a while now, and it’s pretty cool. The thing comes in a slimline pocket happy size, and contains a 3400 mAh rechargeable battery, which you charge up via the USB port on your computer. Once full, it will keep your mobile phone and other handheld devices going for a good while. The company claims you’ll be able to recharge your device between 3 and 5 times, which is pretty impressive if true. It certainly lasts a long time in normal use.

I used it to keep my cell phone going over a recent overseas trip and it was perfect, and I didn’t need to lug around charging cables, international socket adapters or anything else. The kit comes with adapters for all the most popular phones and devices. Recommended. £24.95.
