Solar Chargers and Power Banks

Solar phone chargers and solar power banks compared by stated panel watts, battery capacity in mAh, output ports, weather rating, weight and included cables.

What to compare in solar chargers and power banks

Small solar chargers and power banks look alike on the shelf, but their ratings tell different stories. The listing's own numbers separate a useful gadget from a gimmick.

  • Stated capacity: Power banks list mAh at a cell voltage, which can look bigger than the usable output. Compare the figure as the listing gives it.
  • Panel size on the unit: A small built-in panel adds a trickle at best. See whether the listing shows a separate foldable panel and its watts.
  • USB output: Look for USB-C power delivery and its stated watts if you charge a laptop or tablet.
  • Weather rating: An IP number counts only if the listing states it. Otherwise assume the unit needs shelter.
  • Extra features: Lights, compasses and crank handles add weight, so ask whether you will use them.
  • Weight: Weight on the listing adds up on a trail, so compare it for like capacities.

Match the product to the habit. A bank you charge from a wall suits commuting, while a bank with a foldable panel suits trails, and the listings tell you which one you are actually looking at.
