Author and tester
Hi, I'm Martin. Through my experience of living in the wilderness and doing nature crafts, I know how important the right equipment is. I want to help you to be well equipped for your adventures. More about me on my "About me" page.
Today, let's take a closer look at the product "BigBlue 28W solar charger".
My evaluation and experience
I still remember the day vividly when I built a cabin in the woods with my two kids. Phones dead, camera at its limit - and then? Sunshine! Boom, my BigBlue 28W solar charger out, hung in a sunny spot, and Tada: We were back in the game.
In the middle of the forest, far away from any power outlet, every second of sunlight counts. That's where my BigBlue 28W solar charger comes into play.
This thing is a real sun catcher, easily converting up to 24% of solar energy. And all that completely free of charge. And with the built-in ammeter, you always keep an overview of how much power is currently flowing.
It's so simple that even my kids have fun finding the best spots for it.
I particularly find two functions practical:
- When hiking, the panel simply attaches to the back of the backpack. The eyelets hold everything securely with carabiners.
- If the sun is gone, the panel can automatically return to normal charging speed when there is enough sunlight available again.
It's not only a great find for us forest adventurers with smartphones and cameras. Anyone who is out and about and needs to keep their gadgets running will love it.
Whether you are a hiker, camper, angler, climber, or bushcrafter. Only if you plan to camp in the deepest shade, it could be tricky.
A power bank is not included here, so why not take a look at the "Anker 325 Powerbank 20,000 mAh." It fits perfectly with it.
I like that
- Catches sunbeams like nothing
- 2 USB ports, can charge 2 devices simultaneously
- Free & more sustainable energy boost – except when it is dark
- Securely stowed, thanks to the bag with zipper
- Easy & small to fold together - completely without "where do I put this now?"
- With digital ammeter
I do not like
- Unfortunately no energy storage function
- Yes, one must still carry along an extra cable - sometimes annoying
What other buyers say about the product
Other users are generally very satisfied with the solar charger - when the sky is clear and direct sunlight, the power supply works wonderfully.
Many customers emphasize that their devices are charged quickly and efficiently with it. They also appreciate the handy and foldable design. The equipment with the ammeter is highlighted as helpful for aligning towards the sun.
However, there are also criticisms: Especially when it's cloudy or in partial shade, the charging performance reportedly reaches its limits according to some reports. Additionally, the display of the ammeter is reportedly difficult to read in strong sunlight.
But when the sun is shining, everyone is quickly happy again.
My rating and conclusion
The BigBlue 28W solar charger is a loyal companion for all sun worshippers and outdoor enthusiasts.
It brings independence and a touch of green energy to every adventure.
Compared to other solar chargers, it stands out for its efficiency, lightness, and the integrated ammeter.
So, if you don't want to stumble around in the dark outdoors, grab one!
