The product works well. It is pretty big and heavy, so do not plan to keep it in your pocket. The solar option charges very slow, do not count on this as a quick option to charge the battery. Charges my cell phone fully about 3x before needing to recharge the portable battery. Works as promised, I would buy again.Holds plenty of power, I charged my phone 3x, then used it to power a red light therapy belt for an hour and it's still going! Not sure how efficient the solar panel charging is yetThe Charger has many ports and built in cables, and the only real downside is how long it takes for the charger to actually charge through sunlight.It arrived in time for my trip. But the adapted I needed was broken but I didn't have time before my trip to return it so I use the charger cord since it's the same android charger. It was disappointing. I should have returned it for convenience but I didn't.Returned it as it was just too heavy for backpacking. Didn’t have an expandable/ foldable solar panelsGreat for traveling if you don’t like wires everywhere. And when it isn’t being used, I put it on the dashboard and let it recharge. Fantastic product.Great power supply for phones or tablets for on the road or cabins with no electricity.The solar panel part started delaminating from the rest of the pack
