I keep this good quality solar panel in my window getting western exposure and connected to a 12 volt 7ah battery to keep it charged by the trickle charger. I then connected it to an inverter and have power for laptop, cell phone, etc that I can charge during a power outage. It’s slow at 20w panel but trickles the energy to charge the lifepo battery. Highly recommend!

I've got a couple bikes out back being stored for winter. It's been fairly sunny so I got this to keep a charge while they aren't in use. It doesn't seem to be sunny enough or powerful enough to charge from a dead battery, just trickle charge so it doesn't delete over time.

I have been using solar panels more over the past couple of years to help power and backup various devices while out and about so when I saw this panel I wanted to grab it. Overall, it should work although it does tend to come in consistently below the 20-volt claim, not much at 18.9 but still worth mentioning. They provide you with three different connectors but frankly I am not sure why you would use the cigarette lighter adapter. I also wish that they would have included either a USB port or adapter, but I will have to find a workaround for that. I am not a big fan of the mounting options either, they give you a couple of clips and four suction mounts, but neither is a great option. In fact, if you look at the instructions, they even warn you to pay attention if you use the suction cups because they might not hold. With those points made, I still think that this is a nice option to add to a purposes collection of solar panels.

Works well for charging my power bank, but I did need to buy an SAE to solar adapter for it. Just keep that in mind that the included jumpers don't work with the typical solar power connections. They will work for an automobile or other vehicle as that seems to be what this panel is designed for, but it will work to recharge your power bank if you get the right cable. I may end up buying a larger one down the road to charge faster.
