The solar cells of SP100 are connected in series, any shadow on it may cause irrreversible damages to your panel when it's working.
- TRY MORE ANGLES to the sun to get best output

Please try as more angles as you can to the sun, which is one of the biggest factor that affect the output of your solar panel. There may be 20 watts difference between best angle and other angles.

When I recieved my SP100,I was able to do some preliminary testing on a partially cloudy/sunny day. I tested with my Bluetti PS54 portable power station, and was able to peak at 96 watts during late morning hours. I live in west central Georgia USA. As a consumer and owner of two SP100 I can say this panel is solid. Being portable I am able to store and set up easily when needed. This Xtar customer highly recommends the SP100 solar panel.
works great and the quality is awesome. I wish it would have a longer cable that connects to the battery pack. i guess i have to get an extension. I like to keep my battery pack in my tent and in order to do that you need an extension to be able to me the panel in the right positions..
I purchased this panel for charging my Bluetti while on caping trips, I ran a test on my back patio to see how it performed. I set it up and plugged it directly into my solar generator and right away i had 110W it charged from 50% to 100% in just 1.5 hour, pretty impressive for a 100W panel. The SP100 seems well made and well engineered, should hold up well, very happy with my purchase!
This thing will charge my phone as fast as my wall outlets when the sun is at its peak. Pleasantly surprised. Kept a dozen peoples devices charged throughout the weekend.
Great buy when you can use a coupon or there is a sale. Pros: - Industry leading Sunpower cells -Solid copper backing / foundation (vs cheap metal paste) in the panel construction for superior conductivity and longevity. Never seen this before in a solar panel. Amazing quality!!! -quick to set up and take down -a two-fold panel takes up less space vs four-fold panel if user has limited space to deploy -no apparent sag in the panels when deployed for use -nice thick legs behind each panel which a strap / buckle system so you can angle the panel at 3 different angles to the sun! Very versatile :) -Long, thick 10ft built in cable for connecting to a power station. Extension cable also available to purchase to provide 20 feet of cable. Suggestions for future models: -install an indicator light to the base of the pre-installed cable so a user knows the panel is active and functional when deployed. -include a few more adapters or optional cables (like the extension cable) like female DC 8mm to Anderson or XT60, XT90 to increase compatibility among portable power stations.
Got my panel yesterday. I like how small and portable it is. Just simply tested it in the garden. Everything is good. Will take it on my weekend trip.
I ordered two panels to use with my Bluetti AC200Max and the panels look great, folds very nicely and are easy to carry and store. I watched some videos on YouTube comparing different foldable solar panels and XTAR SP100 seem to be the best choice for me. One of the panels had unfortunately been damaged in the delivery and was a bit cracked and only delivered 50-60% compared to the other panel. I contacted XTAR and after a quick response and a video review they sent me a new panel without further discussion, which made me a very happy customer! The panel delivered 85 watts in the early morning sun here in Sweden and I expect it to deliver full effect under optimal conditions. A great product and great customer support!
Excelente, não podia estar mais satisfeito.. já comprei mais um... em boas condições ultrapassa os 100w. Recomendo
Looking for a very good, yet affordable Solar Panel to quickly charge my Bluetti EB70S which the XTAR SP100 was able to deliver via 105W sustained. When compared to my former Jackery Solarsaga 100W which only maxed out at 90W, the choice is clear that the XTAR SP100 is the only choice which under promises and over delivers. Hard to believe what a superior panel the XSTAR is so I took a few pics for proof and also did additional some research on YouTube only to find the same great results.
Did a quick test, seems to work well, even in low sun I was getting a charge to my iPhone 11 pro max via the usb c port using a usb c to lightning port. Highly recommend to buy their EU4S, it was really helpful. Have to test more thoroughly, but first impressions are good. Seems well built, cables and case seem to be high quality. If I get more review data I will update.
I thought that the charging station was also a power bank, so that I could charge things later when I put the solar panels away, but it doesn’t appear to be that
Five Stars! Being very interested in the concept of solar power, I purchased two XTAR SP100 Solar Panels to charge my portable power station. I was surprised it was so lightweight and compact and very excited about my first attempt at using solar power. I found everything I needed was included and hooking it to my generator was quick and easy! It was cloudy for a while but still charging, and when the sun broke through the charging was extremely rapid! I was really impressed! While boondocking in my SUV, the XTAR Solar Panal takes up very little precious space and is an extremely invaluable addition to my off the grid outdoor experience. Also, I live in the country and storms take a heavy toll on my electric service, sometime being without power for several days. The XTAR Solar Panels keep my generator ready for charging my cell phone and IPAD, making coffee, even cooking with a crockpot or on an electric burner. GREAT PURCHASE!
The solar panel and accessories are one of the best kits available. The SP100 consistently provides power when conditions allow. I highly recommend the Xtar SP100 solar panel and eager to try new products that are being offered.
The extension cable is storable in the SP100 zipper pocket is there when needed.
The SP100/EU4S is best on market for charging a multitude of devices. Very versatile for emergency or overlanding this combo is a must have. Couldn't be please more with this purchase.
I did not think this small unit would work well, but it does. Under direct sunlight, it works great.

first time using it. seemed to get at least 90 watts from the panel and charged the battery in a short period of time.
These panels put out 115 watts tops. That’s amazing!
This solar panel is inclined, with an angle the sun will reach it more than a vertical panel. You can easily protect your solar generator by hiding it behind XTAR large solar panel to avoid overheating by the scorching summer sun like in Florida : )
I’ve had this for a month or so and it is efficient and the fold up velcro legs are great! Glad I bought.
The charging time was good for the battery unit. I was content with it. I would not recommend for personal hiking trips if it’s just you and your backpack given the dimensions of it but if you are going car camping or driving your car to a location and setting up your tent there, I highly recommend it. Read the product description and dimensions based on your needs. It worked well for me.
This is a good panel that we use on our Anker 767 Power House. Free shipping and no tax. Great!
