A portable power pack for charging on the move

The Cygnett ChargeUp Pro 20k will fully charge a 12in MacBook with enough left over to wake an iPhone

Now that so many trains and aircraft have power plugs, I haven’t been keeping as close an eye as I used to on auxiliary power packs. Yet we carry more devices with us than we did when the British company PowerTraveller was pioneering this technology. Also, it’s not uncommon to find yourself in business class with a non-functioning power outlet. Additionally, in-flight plugs don’t supply enough power to charge your device – merely to keep it operating. So all in all, an auxiliary power source is still necessary for business travellers who rely on getting a full day’s work done on a long-haul


Cygnett makes some of the neatest power packs going. The size, finish and feel of this 20,000 mAh pack are exemplary – it slides into any flight bag and has prodigious power. I was able to get a full charge for a 12in MacBook plus a little left over to wake an iPhone X from the dead. For £149.99 and quite a bit extra in dimensions and weight, Cygnett’s top, 27,000 mAh model (in black only) would have fully charged the phone too – but since I’d never get on a flight without a full phone and don’t use phones for much en route, I find the 20k more than enough.
