Gear Matters: Highly Charged Walking

Gear Matters: walking gear blog by Sherpa Expeditions walking holidaysEvery month our resident guide, John Millen, brings you an anecdote, update, or tip on the gear you are likely to use on a walking or cycling holiday. Always from his personal point of view. This month, he looks at the best portable chargers and some points to consider when choosing to buy a power bank for your next cycling or walking holiday.


The following scenario is a possibility on any tour, but more significant when you are walking in the mountains. There is an accident, you reach for your phone to make the emergency call, but, you forgot to recharge it last night and the one bar of power left is already flickering! However, help is at hand: you reach into your backpack and pull out a USB connected portable charger from which the device can feed off and perhaps recharge from fully. It could literally save the day.

I have been carrying one of these chargers on my walking holidays for some time now and had to use it to recharge my phone and camera, especially in remote destinations where there was no power supply.


Size & Capacity

Most portable battery chargers either are lipstick sized or a similar size to a mobile phone containing a lithium battery. Specifications of course vary, but they nearly all have USB couplings to power any kind of device that can be USB recharged. The size of the power bank will of course effect the weight, but also how many times you can do a full recharge. Measured in milliampere hours (mAh), the number of times a unit can recharge your phone or camera depends on its capacity and the capacity of the device itself. In order for your device to get at least one full charge from the charger, make sure the phone’s capacity is no more than 70 percent of the charger’s capacity. Another important consideration is the portable charger's power output. The higher the better, as it means it has the potential for powering up a device more speedily.

Hardware at Low Charges

Nearly all the portable phone chargers are very economically priced. On the small side, but beautifully light at less than 100g, are the little Barrel rechargers for example by Belkin or Anker. They have capacities of around 3000 mAh - enough to recharge a smartphone once or twice. At the other extreme, weighing five times as much, is the Zendure A8 Pro. This one has a capacity of 25,600 mAh and has four USB slots so you can really go to town recharging basically anything. In between these options, you can look at popular and cheap models from places such as Amazon, such as the AmazonBasics Portable External Battery Charger of which you can get models with different power ranges from 2,000 mAh to 16,100 mAh.

Get Wired

Before you head for the hills and set off on your walking holiday with your portable charger, let me supply you with a couple of obvious suggestions:

  • make sure that the charger is itself fully charged (this can take hours depending on the capacity) and
  • take the correct USB coupling cables for your devices before you leave.
