The dad navigating on his phone with it at nine per cent
What it is
A 10,000mAh Qi2 certified magnetic power bank at 15 watts, slim enough to hold on the back of a phone while in use. For recent iPhones.
Why we picked it
Magnetic means no cable, which is the difference between a power bank that gets used and one that stays in a drawer with a tangled lead. Ten thousand is roughly two full phone charges, which is the right size for a long drive or a flight rather than a week away.
