A solid external battery pack is an indispensable item in many tech fans’ gadget bags, and it’s easy to see why.
The freedom and extra peace of mind provided by these flexible chargers can be a saviour if you want to work outside, or simply can’t get access a mains adapter while travelling or camping.

The Anker PowerCore 20100 charger is one of our favorites and enables you to charge two iOS and Android devices at the same time. It’s even compatible with Apple MacBook models that utilise USB-C (USB-C to USB 2.0 cable required).
Anker says the 20,000mAh cell within the PowerCore 20100 will charge an iPhone 7 nearly seven times, while you can expect five recharges from a Galaxy S smartphone.
This product has been on sale at Amazon US since Black Friday and Amazon seems to be keeping the deal around as Cyber Monday week gets started.
Anker also touts its PowerIQ and VoltageBoost tech, which it says “combine to ensure your devices charge at their their fastest possible charge speed.”
There’s also surge protection and short circuit protection to ensure your devices won’t get fried if something goes wrong. At just 0.78 the sleek charger won’t add too much weight to your bag either.
All Anker products come with the unbeatable 18-month warranty, which is nothing to be sniffed at.
