One gift idea worth looking at for most people would be a power-supply accessory for their mobile devices. These come in the form of power-banks / external battery packs, multi-device chargers or charging devices that use other energy sources. They can also benefit mobile-device accessories like Bluetooth headsets or wireless game controllers that obtain their charging power from USB sockets.

The power banks or external battery packs have their own high-capacity battery but are charged from a USB-based power source like another USB battery charger. There are some of these battery packs that can work from four AA Duracells, which can allow you to charge up your phone from a set of batteries you buy at the local convenience store.

The USB external battery packs do come in a variety of styles from a small cylindrical style similar to a lipstick tube, through something as big as a small padlock, to a flat “candybar” style that doesn’t take up much room in your pants pocket while it powers your smartphone. But most of these units have differing battery capacities and power outputs and the units with a large battery capacity and 2.1A power output can earn their keep with the tablets or the high-end smartphones. As well, those battery packs with the high capacity can work well with situations where you make heavy use of your phone’s features like using the maps and navigation function, play music, use workout-tracking software or play games.

Similarly, these battery packs will earn their keep with those of us who spend a lot of time talking on our mobile phones because this can eat in to the phone’s battery’s runtime and the external battery will typically give you that extra battery power so you can talk longer. For example, I have used one of my USB battery packs to allow someone who was using their smartphone to counsel another person over the phone to talk longer with that person without fear of being cut off by a dead battery.

Another power-supply accessory worth considering are the multiple-outlet USB battery chargers, devices that I often refer to as “charging bars” but are also referred to as “charging stations”. These devices plug in to the AC power and can charge at least four USB-connected devices at once. What’s more is that they have a very high power budget with some of these devices even having the ability to give at least one of these sockets a dedicated supply of 2.4 amps. This can allow the device to comfortably charge one or two tablets and many smartphones concurrently, with the ability to provide the right amount of current to charge them quickly.

These “charging bars” avoid the need to plug multiple USB chargers in to a powerboard to charge or power many personal-electronics devices at the same location. One area where these devices earn their keep is the kitchen bench where a household will be “topping up” their mobile devices’ batteries for the day while they are having breakfast for example. Or, you may find that in an office a group of workers have their smartphones or tablets nearby and want to run these devices from external power to avoid compromising their devices’ battery runtime.

They also can be useful for charging up USB external battery packs and other accessories in such a way that you could charge your smartphone, a Bluetooth headset, an external battery pack and something else at the same time.

There are some other mobile-power-supply gifts out their that harvest energy from other sources like the sun or heat from a fire. A lot of these devices have been pitched as “novelty” devices and some of them won’t provide enough power to your smartphone or tablet from that energy source. Here, you need to be sure that the device can store a significant amount of power in an onboard battery because the energy source can easily fluctuate which is more so with solar panels or you have to hold it in a certain position to get the maximum power in to your mobile device.

As most of us use mobile devices “to the hilt” for multiple purposes, especially online, gaming or multimedia activity, we are going through our devices’ batteries very quickly. This is where devices like USB battery packs or multiple-USB-outlet “charging bars” are becoming very relevant as gift ideas.
