70 reviews for JMUYTOP Outdoor powerful Portable Solar Panel 5v 21w 40W

  1. Liberatore Accordino

    The parcel has arrived, everything according to the description, meets the expectations, charges the powerbank, but if it will charge, I do not know.

  2. Lelah Pelosi

    I arrived yesterday but in the afternoon so I was able to try it today here in the south of chile there were 8 degrees celcius of temperature, a not very powerful sun and the charger was excellent. I charge a 30% with a bit of clouds the truth on a cloudy day maybe it will charge a little but with the cell phone turned off mmm I must try and if it works it would be great because it would serve me too much.

  3. Alpha Um

    How cool is that…!
    So it is also nice that it works safely U like with meeegaaaa…
    Oh yes that’s really good ..
    Thanks for that u nice work”

  4. Klemens Totleben

    Product in order fast delivery Super recommend the seller, sorry I was taxed on real 82,00 absurd these fees, more in relation to the plate I highly recommend!!!

  5. Zoraida Swick

    The panel arrived in 12 days.Packed well, whole, working. Checked when the sun was in the haze. USB includes fast charging. Via Type-C, the charge is weaker. I will check later in ideal conditions.

  6. Eleri Barnes

    Before Kiev, I took the press for 12 days at once with some cuts. Whiglyadav juge yakisno, about the charge of the important thing, Casati Poki scho, ale I go to nature on the sleepy day will be charged.

  7. Lanie Edwin

    Under moonlight + lights, the current is very small about 30 mA, in the usual light of the Sun 300mA-600 mA, I will continue to test in an emergency, the solar panel is simply necessary

  8. Emma Carra

    fast shipping, tested indoors and it just about charges my phone near the window. It will work well outside. I bought another for my girlfriend, ideal for trips or camping, recommended

  9. Ira Forster

    it works. in a full sunny day output is 5v / 0.5A (as a laptop usb) that means 2.5watt. i don’t know why they sell as 20w. but it works, it charged my phones.

  10. Niam Mullins

    Innovative and compact folding solar panel with 3 Silicon solar cells shipped in only 8 days to Germany – Thank you Seller!

  11. Gianmaria De Sario

    The panel seems solid. It is interesting that there is no traditional glass outside. In general, it is rigid. Material strong as if nylon .. Clips firmly hold the folded panel. I do not know what the durability on the bends will look like-but it is such a type of panels and time will tell. Two carabiners included. There are more holes, so you can pull the rope to better attach it to the backpack. I managed to get 1A 4.6-4.8 V in early spring. The fast charge also charges about 8.5-8.8 v, because the approx. 04V and some devices may have a problem with this, so it’s best to connect the powerbank.. Perhaps in the summer in full sun will succeed more. However, 1A is already a relatively good result. Of course, it depends on the setting and how many clouds there are, but this is not the fault of the panel, just such a charm of technology.

  12. Miriam Perry

    Thank you very much to the seller, fast delivery, I liked everything, I recommend the store.

  13. Valtena Amodei

    look and feel of the received product is above expectations. lets see if it works as described first impression. this is a value for money product

  14. Oscar Álvarez

    Delivery in two Tig. All the time, bring the box itself. Having changed the wound, I saw 1 ampere with the Kuta Kuta, I just put the yak in the photo 0.74a. Vidpovid characteristics

  15. Savannah Brotherton

    They arrived before the appointed date… and they came well protected. They work very well.

  16. Aliya Fernandez

    1. it works, NOT guaranteed when you buy from this site 🙂
    2. in approx. 4-5 hrs of direct sun, charged mobile (5,000 mAh) from 15% to approx. 65% – not bad.
    3. ideal usage: charge a power bank, not mobile phone. Probably UP TO 8,000 mAh per day, in ideal conditions (stationary, full sun).
    4. product photos are misleading, 3-panel is NOT useful for backpacking, not much sun hitting all 3 panels. 2-panel would be lighter, fixed to the lid
    5. better scenario: bicycle-touring, kayaking
    6. negatives and doubts:
    – output (usb-c and usb-A ports) are housed in a ‘black box’, which is so tall (1.3 cm!) that you can’t fold the panel flat (see photos). It should also be positioned in the centre, or at the very edge, not 1/3 way.
    – not certain how durable panel will be after many folding/unfolding
    – weight: 345 g (without carabiner clips) = about 2 x weight of 10,000 mAh power bank.
    Essentially: useful for trips longer than 2-days / weekend.

  17. Fernand Aveline

    Product received in Ukraine at date just as was promised (within three weeks).
    On my latitude 49,83N in sunny autumn day showed 5.03V (idle), 4.97V under the load (0.35A), which is in accordance with declared (Xiaomi RedMe Note charging – 1% per ca 2 minuts). Looking for using the Panel in summer time.
    Definitely recommend the seller and the product.

  18. Major Woodrum

    Charging Samsung S23 from 65% to 85% in 15 minutes with shroud cloud cover. Without cloud cover probably from 20% to 100% in 1 hour.

  19. Antonio Levine

    Works. As far as I understand-there is a silicon plate inside under the plasticizer millet. I broke the tip and heard a crunch. I checked it at random, but managed to see it in cloudy weather 9 v 0.5A and 5 V 1.85a in the sun

  20. Olevia Lauder

    It’s hard to say how it will perform in full sun (at my place, it has been fully cloudy for several days). In low sun the maximum that was achieved was 0.2A , I assume that in full sun it will be better. The design itself looks solid, it’s hard to say quickly if it will perform.

  21. Aamir Boyd

    21w is a bit optimistic… but I get about what I expect out of it and the construction quality seems fine.
    It’s great that it will supply 12v over usb.

    I tested with dummy usb load and pulled as much as I could before the usb supply would drop to lower voltage. ~12watts was the most I could get and it was pretty consistent across all modes: 5, 9, 12v.

  22. Lorean Soni

    It can turn on a small light, but not many other USB itens such as USB fan, a stronger light or charge a cellphone.

  23. Durante Sciara

    Works like a charm
    i assume that the summer sun will charge even better

  24. Jaimee Harter

    It works. Disclaimer I live in SoCAL so your sun may be different.
    To test the power of this 40w panel I decided to give it something easy as all my other devices were already charged.
    PROS: * Charged my half charged mp3 player in less than an hour
    * Easy to pack, folds and even snaps
    * Low cost
    * The charging light shows that cells are work.
    * Comes with two small carabiners to clip into position while charging.
    * Super fast delivery to Southern California.

    CONS: *Although sturdy material a grommet would help to distribute
    whatever weight is added to charger while charging.
    * Cables would be nice, but not necessary
    * Storage case would be nice, but not necessary

    If you are looking for an inexpensive charger that works this was the one for me. I will recommend this to friends, and will buy again should I need another.

  25. Mammie Aguiniga

    This is a pretty good product. I would definitely recommend it and that’s coming from a purchaser here in the United States.

  26. Kholmatzhon Daniarov

    solid panel at a solid price. works good and has excellent build quality. good bang for the buck.

  27. Wendi Raver

    All OK. 5 cotton fan turns and this is in the morning sun. in general-normal. Its money is worth.

  28. Derrick Sclafani

    Pleasantly surprised by this solar panel! In direct winter sunlight I’m getting a good 10 watts via USBC to my battery bank. Using a voltage tester, it was putting out a good 9V 1.1A in direct sunlight. I was also pleased to see that it has a protection circuit, and drops to 9V 0A if there’s insufficient current to maintain the conversion. Considering how small and light this thing is, I’m surprised to see how well it converts! I can’t speak towards durability, but it’s a pretty light material so I wouldn’t expect it to be super rugged.

  29. Daanyal Shepard

    Now it is necessary to test it in load to see if capacity

  31. Cindi Mcfarlin

    seems to work, it charges, but I can’t yet tell how powerful it is. the sun is not shining often now.

  32. Reiko Jeanlouis

    I haven’t tested it yet, but this is the second I buy… I really liked

  33. Devon Huntoon

    Excellent product and very complete

  34. Clarita Pursell

    Apparently well made and will work fine. I still didn’t use it because here the sun is still behind a sky full of clouds. As soon as I use it, I can come back and write down the results.

  35. Gérald Noir

    Good enough. 6.3w after noon from winter sun in a not completely clear spot. 21w seems a bit unrealistic, but it should peak at around 13w during summer, which is completely fine for this size and 20€ price tag.
    materials look pretty good – hopefully nothing delaminates over time.

  36. Marchelle Dowden

    Works very well.
    8% Charge on a 5000mh smartphone in 30 min.
    Perfect

  37. Gage Edmonds

  52. Roderick Roth

    The build quality is good. It was not yet possible to check.

  53. Jaqueline Phipps

    Product as announced, I did the test, however the day was a little cloudy, the average was at 4/5min each 1%, I believe that on a strong sunny day should charge a little faster. The product works.

  54. Fukumoto Shusake

    finally a solar panel from China that … works…

  55. Carla Poole

    Very good board, in the camp is for charging power Banke, mobile phone, flashlight and portable fan

  58. Enrique Lutz

    The product arrived in Kharkov in 9 days! The fastest delivery in my memory. I will test the panel in the near future. Good, the rashists in the neighborhood contribute to this. All the world.

  59. Thibault Silvestre

    Excellent solar panel
    Good materials quality fast charging
    Recommended

  60. Anacleto Adornetto

    Very light, wonderful for on the go, without direct sunlight no sufficient function, in direct sunlight the panel works perfectly, enough energy to charge my smartphone, with around 20 euros just OK from the price… The article came very quickly, undamaged with me, delivery with Hermes
