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: Definitely works and will be very handy for camping trips - I've had this item for just over a week now, so wanted to leave an honest review of my experiences, as I was unsure before buying and hope this review will help others to decide. First off, the positives - it really does work. It probably helps that we've had a sunny spell the past week, but in that time, I've used it to charge phones, tablets, power banks and a switch. On a sunny day I've left it out to charge a 16000mah power bank from 0 and it got it upto 50%. The most I've ever seen it put out is 3.1a, but this was in direct sunlight on a really sunny day. Most other times, it's somewhere between 1-2a. That's been enough to slowly charge a phone or power bank. If it's cloudy, usually under 1a. In those cases, it's struggled to charge a phone, but that's probably to be expected. The way I plan to use this is for camping. Charge the power banks during the day, use those to charge the phones at night, then recharge the power banks the next day. So far this seems to be working. Overall I'd say this is definitely worth it. You just have to be a bit realistic and realise it's not going to charge your phone in 10 minutes or in cloudy conditions. If you plan how you're going to use it and have some way of storing the charge it generates to use later, it works really well.

### ⭐⭐⭐⭐ 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.
