Review: Capable solar charger (but not 28W) - The bad news: the highest charging current I've had in ideal conditions (Scotland, midsummer, midday sun, clear skies) is only 1.7/1.8A. A long way short of the maximum suggested by the manufacturers. The good news: 1.7A is an extremely useful charging current. The Big Blue can also pump out some solid current on overcast days - close to 1A with light cloud. Obviously really heavy cloud will drop the output to zero. In mixed weather conditions I found it more than capable of keeping phone, headtorch batteries etc charged on an extended camping trip. My phone gets used pretty heavily - photography, news & weather if I can get online, Kindle books etc - so this was a solid performance. I also used a couple of 18650 batteries and a Nitecore F1 charger as a lightweight buffer for the rainy days when I couldn't deploy the panel. On sunny days there's charge to spare to fill up the batteries. The 3 stars for water resistance is just my best guess. The unit seems to cope OK with a smattering of rain but I wouldn't want to get it really soaked. The panels seem to have a waterproof coating but I doubt very much if the main electronics, under the display, are waterproof. Why does water resistance even matter for a solar panel? In showery conditions the Big Blue can gather a lot of useful charge in the bright spells. A fully-waterproof unit could be left out unattended while you get on with something else. That's the bottom line for portable chargers: do they fit seamlessly with daily life in the field or does it feel like device-charging is starting to dominate your time? The Big Blue performs well enough not to be a nuisance. The display is great - indispensable really. If you want to learn how best to use the panel you need to see how well it works in different conditions. I measured the weight at 610g on scales of unknown accuracy. All in all, I like it. May not perform as well as claimed (I didn't really expect it would) but it does perform well.
Review: Keep your devices powered up when you are remote - I love my portable camping solar panels. Have taken them on several hikes in the UK and France and they are great for keeping my devices topped up with power. The fabric is durable and the design is simple to use with two USB ports. It is worth noting that to get the maximum power output you need to use both ports. It will only provide a maximum of 2.0 per port. If works well in both direct sunlight and shade, although the power drops off a lot in the shade. For best output I prop the panels so they are at 90 degrees to the sun if it isn’t directly overhead. I also pair it with a portable battery pack, which I then charge my other devices with. As more devices switch to USB C, I would look for panel with high output on a single port to charge the battery pack faster, but this model will keep an iPhone topped up. I also like the display so that I can adjust the position to maximise output.

### ⭐⭐⭐⭐ Portable solar panel.
*by R***I on 21 August 2025*

The portable solar panel arrived as ordered, I unpackaged the item to see small scratches on the digital ammeter screen, which if it was brand new it shouldn't have. It does not appear to affect the ability to charge and other than that appears to work as described.
