The Charmast is the cheapest pack in this ranking and the only one that solves the cable problem by building cables in. The listing describes four built-in cables and a 10000mAh capacity, which means you can leave the house without a separate charging lead and still top up most phones twice or so.

The trade-off is capacity rather than features: 10000mAh is half the energy of the packs around it here, so it suits a day bag rather than a weekend away. At the time of collection it carried 15,685 ratings at 4.5 stars. Everything here comes from the Amazon listing rather than our own testing.
