The lid of this pack is a solar panel and the body is built to hang outside a bag rather than inside one. An IPX4 seal keeps rain, dust and sweat away from the electronics. A small readout tells you what is left in the cells before you connect a phone.

Most packs stop being useful the moment they run flat, which on day three of a trail is exactly when you want them. Daylight keeps this one slowly gaining instead of only losing. Rubber-edged corners mean it can ride where you can see it.
Sunlight in, a phone that still rings out.

Hang it panel-up while you walk rather than tucked under a flap. Solar gain is gradual, so count it as a supplement to a mains charge and not a replacement for one. Dust on the panel costs output, so give the glass a wipe when you stop.

Clip it on before the next trip.
