If you need to power up your smartphone but are nowhere near an AC outlet … well, that's why Sweden's SiGNa Chemistry and myFC developed the PowerTrekk fuel cell/battery. While it's a handy device for off-grid device-charging, it's not exactly the type of thing that you'd just slip into a purse or pocket. myFC's new JAQ, however, is exactly that. It's being billed as the world's smallest fuel cell charger.
Phone charging cables can sometimes be awkward to plug in, pull phones off surfaces or get damaged when bent. Inspired by Apple's MagSafe chargers for MacBooks, the MuConnect is aimed at making charging your smartphone a snap.

although they won't do you much good if they've lost their charge by the
time you finally need them. That's where the Nipper comes in. It
provides some extra juice to your phone via two easily-obtained AA

Although battery life has improved markedly in recent times, most laptop users will still find themselves looking for a top up from the nearest wall outlet more often than they would like. MOS is providing a more flexible option for travelers with its Reach Go that is the first power bank capable of charging a compatible laptop at the same rate as a wall outlet.
Scientists at the Korea Advanced Institute of Science and Technology (KAIST) have developed an omnidirectional wireless charging technology that can charge multiple devices at once, at a distance and, crucially, at peak efficiency regardless of which way the devices are facing. The technology, said to be safe for humans, is set to be trialled in cafes and offices and could allow for much more convenient charging of mobile devices.
Our mobile devices running out of power is a constant worry, although portable chargers can help alleviate some of that anxiety. CulCharge, a new charger/powerbank still in its concept stage, is intended as an easy-to-carry option as it is small enough to slot onto a keychain.
