Backpack Solar Panel AquaBlue

THE PROS Very modern looking design with a shiny finish. Easy to clean outside shell. Plenty of settings on the shoulder straps. The solar panel can be taken off and stored inside when not in use. It comes with a charging cable and a netted compartment on the back of the panel where you can store your phone or power bank while it's charging (not very practical as you don't want you phone or battery just below the heated solar panel). Charges best when phone is out of power or has very little power left. THE CONS The backpack does not have a hard back panel. This makes it hard to handle it when (half)empty. It kind of loses shape and falls down unless it is fully loaded. This can be problematic if you are trying to have it sit upright in one place. It also makes it hard to look for things inside as it just keeps collapsing from all sides as you move your hands around. I used it with the Samsung S20 Ultra 5G which has a rather demanding 5,000 mAh battery. The more power there is in the battery, the slower it keeps charging, so above 75% battery capacity it takes about 5min to charge 1% further. There are only two large compartments and two siede pockets, so not many places to choose from if you carry lots of small things in your backpack. Overall verdict: good value for money. It does what it says: looks nice, protects your stuff and charges your phone/power bank.Comes in useful as an emergency charger not a regular replacement for a fast charge source of power.
