This set of lights is rechargeable via solar or usb c. It's got usb a and usb c ports under a nice thick rubber cover on the side. They recharge using solar.

There is a color changing mode and 6 different colors to choose from. I wish there were more colors, but that could be a cost limitation of the led set they're using on this product.

Setting up is very easy. It is convenient to pack and unpack. The sos beacon is great and the battery seems to last forever. Their weight and packability may not be ideal for backpacking or ultralight camping setups.

The longer version’s string is detachable which helps with the setup. Perfect for a table or a small tent, but rather short if you are trying to string it between trees. While they look exactly the same, the 18feet one was directly connected.

The bulbs and the line with which they are strung together are durable, high quality and appear they will hold up a long time. With careful use, they last all weekend, or more. Nice sized bulbs.

It's ridiculously expensive for what it is. Fire hazard and waste of money. Not worth the price. Not what is advertised.
