Portable Power Chargers


Whilst there are far greater problems in the world than a flat battery on your gadget, it’s still frustrating when you it happens. We’ve all been there from time to time, and if you are away travelling or hiking through remote areas, it becomes an occupational hazard. You find yourself rationing your use so that there is battery left in an emergency, but there is an alternative – portable power chargers, allowing you to recharge the battery on your gadgets even without regular access to mains electricity.

Solar Power Chargers

Solar power chargers, such as the Geonaute ONpower 300 Sun Charger, are one option for keeping your gadgets fully juiced whilst on your travels. There are two major benefits of solar power chargers – firstly it is a free, environmentally friendly source of electricity. The second is that you only need sunlight in order to charge the unit, and the charge will then be stored until you want to use it. This means you can be miles from the nearest settlement and still be able to charge your charger.

There are a couple of downsides to solar power chargers however. The units are generally relatively large in order to accommodate a large solar panel – the ONpower 300 is similar in terms of dimensions to a tablet, so is portable but not something you could store in a trouser or jacket pocket. The most significant downside however is the reliance on the sun – in low-level sunlight or at night it will be very difficult to recharge the charger itself. Therefore it is important to assess what the sunlight conditions will be where you are travelling to in order to work out whether a solar power charger is a viable option for you or not.

USB Chargers

If a solar power charger is not a viable option for you, USB chargers are one alternative. They store electricity in a similar way, but the unit is charged via the mains instead. Therefore if you charge the unit fully before you leave, you can then use it when you need it and recharge the unit whenever you next have access to mains electricity. The other advantage to USB chargers is that because they do not need to accommodate a solar panel, these units can be very small, easily small enough to carry in your pocket. The downside is that you need access to mains electricity to recharge the unit, though if you will be without access to the mains for a long period you can opt for multiple units or a unit with a higher storage capacity.

Portable power chargers are a great way to enjoy using your gadgets even in the most remote locations. By thinking about what the conditions will be like on your holiday, both in terms of sunlight and how regularly you will have access to mains electricity, you will be able to identify which portable power chargers have the features to meet your needs and enjoy the freedom provided by not having to ration the use of your gadgets.
