Solar charging that fits in a bag
This EcoFlow model is made for travelling light. With 45 W of rated power and a USB-C output, it recharges a phone, a tablet, a power bank or any other device that can take power through that port. It opens in seconds, sits in the sun, then folds back to 222 x 309 x 40 mm.
Who it suits and why
Hikers, cyclists, kayakers and travellers: anyone who spends the night far from a socket gets a discreet energy reserve. On the professional side, it can accompany a guide, a reporter or a field technician who needs a radio, a torch and a smartphone to stay working through a long day.
Materials and build
The panel is based on N-type TOPCon monocrystalline silicon, with an efficiency above 25%. Its protection rating is IP68. Unfolded, it reaches 980 x 309 x 16 mm. Its weight of 1.4 kg and its mounting eyelets let you hang it from a backpack, a tent or a branch while walking or resting.
Putting it to use
- Unfold the panel and hang it up by its eyelets if needed.
- Aim it at the sun, avoiding any shade, even partial.
- Connect the USB-C output to your device with a suitable cable.
- Check the device’s charging status; if nothing happens, change the angle or check compatibility in the manufacturer’s manual.
The specifications list only a USB-C output, so for a large battery, check in its manual which connectors it accepts. In practice, a 45 W panel is best seen as a companion for devices that charge through USB-C; expect charging to slow down under clouds or when the angle drifts, and plan your breaks around the sun rather than the other way round. A power bank charged during the day can then top up your phone at night.

Precautions
Use a USB-C cable in good condition and do not force the plug. Do not leave a device charging in intense sun if its manual advises against it, because heat can harm a battery. Keep the panel away from open flame and avoid hanging it from an unstable support.
Care and storage
Remove dust with a soft, slightly dampened cloth, with no solvent or abrasive sponge. Let it dry completely before folding the panel. Store it somewhere dry, with nothing heavy on top, and with its cable coiled loosely.
