This review for the SP120 solar panel is without testing as I purchased it to support my EB40 and AC50 Power Stations for remote camping and home power outages. At present, neither has occurred. Since I didn't want to wait on either, I will give an "out of the box" review at this time only and update when tested if possible.
To start, I can't say enough about Maxoak customer service. It started in 2018 with my purchase of the K5 cpap Power Bank for remote camping. Within hours of my Amazon purchase I was contacted by a Maxoak customer service person to make sure I would be sent the proper cable to match my particular cpap device. It has been that way with all my Maxoak devices. You have a question or a issue and they typically respond to your email within 24 hours.
I have been impressed by the innovative design and quality of the three Power Stations I own. The SP120 solar panel, out of the box, is the same. They boast 9.48lbs and that's exactly what it weighs. Nice, easy to carry handle when folded close and two quick release catches to open. In less than five minutes, this compact solar panel can be operational. The attached MC4 connector cables, are nearly 10 feet long, roll up and tidily fits in a zipper pouch on the front of the folded panel. I would recommend the addition of a cable clamp near the junction box so any strain on the cable stops at the clamp and not the junction box.
As an option to the kickstands are three heavy corded loops for hanging vertically when using the kickstands may not be convenient. My usual campsite, hanging on the side of my tent is much more practical. In the carry configuration, the kickstands neatly fold flat and velcro to the back of each panel. I would have preferred the quick release catches in this location but a minor issue in the overall picture.
Similar portable solar panels are not waterproof or say they are waterproof but do not specify to what limit. The SP120 lists a IP54 rating at the panel surface and a IP67 at the junction box. With the IP54 rating, don't set up in the rain but if caught in a shower, the solar panel surface is protected and the junction box is 100% waterproof.
Bottom line, if you're looking for a nice lightweight, compact, go anywhere solar panel that's compatible with all your solar rechargeable Maxoak devices, now and down the road, I think the SP120 is an excellent choice. I'm glad I made this purchase.
NOTE: A picture is worth a 1000 words. I had several pictures to add to this review but no option. Should consider adding this option.
