Upp fuel cells can power most USB devices, and they're super easy to use. In fact, even if you're away from home but still near a power source, you may find it easier to carry an Upp cell with one cartridge to power your devices instead of taking a dozen different chargers and cables with you. The pricing structure for Upp is fairly straightforward, and the good news is that all products are available for purchase now. An Upp starter kit, which contains the Upp cell and a single cartridge, sells for £149. Once your cartridge is spent, you can take it to an Upp exchange point and pay just £5.95 to exchange it for a fully charged one. Or, extra cartridges can be ordered for £49.95. UPP APP The Upp app can offer you even more data and information about your fuel cell usage. It displays graphics showing you energy levels and statistics, including how many minutes or hours of certain activities you can do before you lose power. The app can also show you a map with nearby exchange points so you can get new cartridges when yours runs out. Both the Upp hydrogen powered fuel cell and the corresponding app provide a new way to power your devices, your gadgets, and your life when you're on the go.
