BigBlue 30W Fast Charging Solar Charger with USB-A, USB-C and DC Outputs

As described and quick delivery Good first impressions for quality

Bought it for backpacking but doesn't pack or carry well. Compared to my older and smaller 14W Anker foldable panel, but did not notice any added benefits in charge capacity or speed.

Overall this portable solar panel is awesome: it generates a good amount of power, enough to charge and small devices or battery banks that I own. The materials feel durable and high-quality, and actually using the panel is very easy and straight-forward. It's not necessarily a negative quality, but the panel is heavier than I expected. In most instances this doesn't really matter, unless you plan on taking it backpacking or hiking, in which case I would recommend looking for something that is a bit smaller/lighter weight.

I had high hopes for this solar charger given the price but the more I use it the more disappointing it became without making my own modifications (see below). So: 3 stars for functionality but getting docked two for items that made it non user friendly. Pro: It's relatively lightweight and worked well to charge a flashlight w/powerbank I had. It took all day but did the job. Cons: 1. It does not open 'flat'. If you lean it against something to obtain the ideal charging angle prepare to use something to make the panels all sit at the same angle. 2. The provided carabiners are too large for the grommet holes and cannot be used. 3. There is an LED on the connection module that has no explained use in the manual. 4. There is no dust cover for the connection module or individual dust plugs for the power ports. 5. There is no pouch provided for keeping the power cable or carabiners in when not in use. 6. They removed the kickstand the prior model had that's being shown by all the internet video shills. Changes I had to make myself: 1. Purchased smaller carabiners that actually fit the grommets. 2. Purchased a USB C power meter dongle to help align the panel angle to the sun by gauging the amount power being provided to attached devices. 3. Purchased/added a small pouch to carry the cable and USB C power dongle. 4. Purchased/added some u-channel to clip to the solar panel edges to get it to stay flat. The clips also store nicely on the solar panels when closed if cut properly. 5. Purchased silicone USB port dust plugs (not shown in photos). Seriously, this is an issue outdoors with the small openings especially with USB C. 6. Added a Velcro strap/belt (not shown in photos) just for giggles to keep everything in place while being moved.

It is definitely working, but does not appear to get anywhere close to 30w output. I connected a 20Ah power bank at noon on a cloudless California August day, and it charged 10% in a bit over an hour. So that puts the output at somewhere around the 2W, which is a bit disappointing.
