100W Portable Solar Panel for Power Station, Monocrystalline 100 Watt 20V Solar Panel Foldable Charger for Camping, 23.5% High Efficiency IP68 Waterproof for Outdoor RV Trip

Tried this for first time on Solix fridge. It brought battery from 33% to 80% (daylight ended!) while showing output watts ranging from 88 to 53%. My test was late in the afternoon so I kept reorienting the angle of the panel to restore output watts back into the 80s.Easy to setup and use

Only tested this briefly the day I received it. Easy to set up. I wonder how durable the fabric cover will be out in the field. During my test charging a solar generator, the generator showed 69W output from the panels under mid afternoon clear sky.

Excellent solar panel. Works amazing. I get 97 input watts in full sun and between 40-70 watts on cloudy days.

Many adaptors, easy to carry, charged phone, supports could be a bit sturdier, but they worked. Nice design with pouch.

I specifically wanted a panel that is less than 45 inches in length, so it can fit on a window of that height. This product is actually 48inches long when fully unfolded. It doesn't fit, I'll have to send it back.

This folds up small, easy to pull out and set up. We charged out phones and power banks at a pretty good rate of speed. It is helpful to note this device only changes it does not store power, but it will charge your portable batteries.

I am loving this “Callsun 100W Solar Panel Portable for Power Station.” It is compact, convenient to use, easy to move around, allows for flexible setup and travels well.I love that the built-in controller has both usb a and c ports. This comes in handy as my Anker 523 station can be charged through its c port. Unfortunately my anker’s dc input is a bit squirrelly with the assessory tips,… Both the j and k tip kind of fit, but they are both wiggly and a pinch too long. I can get them to work somewhat sometimes, if they are angled just right. When charging from the panel, the highest input wattage my power station has reported is 59 watts. ( 60w is listed as the c port input max.)When I charged my phone via the c port, it charged at the same rate as it did with my high speed charger in the house. Of course that was with full sun.The fold and zip to pack is fast. The zippered pouch built into the case surrounding the controller is super handy for the cables and the tips. It’s not as handy to store stuff in there while it is being used, since you have to have it unzipped to use it. The Kickstands allow for a good range of angles to catch the sun. A thin piece of fabric keeps them from opening too wide.When traveling, putting this under a bunch of gear can be problematic as that built in controller keeps it from being uniformity flat. Upright it is quite thin and unobtrusive. And it is light enough to put on top of a lot of stuff. It is sooooo much easier to deal with than the old heavy giant panels I have been lugging around in my rv

The CALLSUN 100W solar panel packs a LOT of punch in a small portable package! The panel only weighs ~10 lbs (without accessories) and is ~ 24x21x1.75” folded. The plastic carry handles have strong magnets to keep them clasped together, until you want to open them up. The package includes an extremely useful MC4 to multi-connector cable, having XT60, Anderson, DC7909, and DC5521 “barrel” (coaxial) connectors. In addition, it comes with a package of 10 adapters to convert the DC5521 connector into just about any DC plug your solar generator/battery pack needs. That doesn’t even count the two USB-A ports (one being a QC port) and a USB-C port supporting up to 20V at 3A. This kit has it ALL.This is a two-panel system, each with its own “kickstand” to help position the panel to a 90-degree angle toward the sun. The panel is rigid enough to easily stand up (unlike several of the floppy ones I’ve tested) and even withstood a moderate breeze without collapsing.I tested this panel with four (4) different solar generator/battery banks plus various rechargeable devices including flashlights, lanterns, and mobile phones. Depending on the efficiency of the solar generator’s internal MPPT, I was able to get a maximum of 91 Watts power from the panel. This is excellent! As an Electrical Engineer, I know panels are rated (and typically advertised) at their Standard Test Condition (STC) performance. STC is achieved in a laboratory under controlled conditions - not in the "real-world". Real-world performance is often 75% or less (sometimes as low as 55%) than STC.For a panel marketed as 100W to deliver 91W in real-world operation is amazing! In full mid-day Arizona sun (at an altitude of approximately 4,400 ft (1,341 m) above sea level, the average output of the panel after it heated up was 81W (+/- 3W) which remains excellent (solar panels produce significantly less power when hot). Using an infrared digital thermometer, the panel surface temperature ranged from 145F (63C) to 155F (68C) during prolonged testing. This panel kit has the power, features, and options to keep your campsite fully charged!My only recommendation for improvement would be to use the NEW STYLE female MC4 connectors with the “pinch-to-disconnect” wings for both the MC4 connector on the panel and the accessory cable. As this is a portable panel, frequent set-up and take-down will be the norm, and these new style MC4 female connectors are FAR easier on the fingertips!
