For Sunny San Diego, solar panel charger is a must have. This thing is very compact and light and super powerful. With us now spending more time in parks and beaches because of Covid, the solar charger can save the day. When folded, this charger is almost the size of a small laptop 13″x7″x2″ and it is very light at only 4 lbs. Easy to carry around.The USB A ports can provide up to 5V/2.4A power output which is around 12w if your device can accept such combination. It does provide a decent DC output at 18v and 3A which is pretty powerful for many DC powered devices.Something nice that this charger has compared to similar chargers is the so called SolarIQ technology, so when you connect a device to it, it automatically finds out the best Voltage Amperage combination that can pass through and adjust the power output of the solar charger accordingly to charge it as efficiently as possible.I only have one of these so I couldnt test the parallel charge port and find out how efficient that one is but with the amount of sun we have in San Diego, I doubt that I’d ever need a 2nd one.

The media could not be loaded. Excellent product but the wire is too short it should be at least 2 1/2 m that I can put the solar panel inside the car not outside it.

Love this thing. Its a game changer for backpacking.

I purchased this as an Amazon return for $118 and it’s worth every penny. I use it to power my iPhone and sometimes my computer and it doesn’t take long at all, and that’s usually through my living room window. Once folded up its footprint is surprisingly small. I highly recommend this portable, powerful little solar panel.

bought 2x and used them for almost 2 years these are amazing solar panels for emergency home use and very portable for campingpeople who are giving 1 star reviews have no clue on how to use solar panels; you can tell from there review pictures. 1st thing you never lay solar panels flat on the ground at 0 degrees they will only be efficient at high noon for 15 min.for panels to work properly you have to set them at an angle towards the sun and it depends on your location for summer its 25-40 degrees depending where you live and winter its 55-70 degrees again depending on where you livei simply use a piece of card board at an angle and lay the panels on the boardputting 2x together in parallel configuration i got 120wtts hitting the max load for the batteryif your new to solar farming please watch some you tube videos first this is not a plug and play hobby, some knowledge is required

Used the panel in the prairies during winter, January 8th to be exact when solar output near its worst. It charged up my phone laughably fast while I was tethering. I’m kicking myself in the ass for buying 1 Jackery instead of 2 more of these. A Jackery isn’t even water-resistant for christ’s sake so in the rain you’re screwed. With the Dragon, you need to cover up the junction box but any person with a bit of common sense can jury-rig a bag to fit over it so that’s negligible. The design is sold, weighs roughly the same as a standard laptop. This is probably the best deal on Amazon for a portable solar panel, and it’s so much more portable than the Jackery. Does anyone want to trade their Dragon for a Jackery?

Update Sept 13 2021: I’ve contacted Amazon, these panels are falsely advertised. Under no circumstances will you approach 70 watts on one panel. If you read the information on the panel itself, @18v 3A the max wattage you can expect is 54 under perfect conditions, account for efficency loss you’re @ about 30 watts which is right where both of mine sit. $189 for a 30 watt panel? No thank you. The actual output is 35% of the advertised wattage, at best.Update Sept 12 2021: Looks like I’ve figured out the issue, they’re advertised as 70 watt panels. That’s their open circuit rating, the second you apply a load it will immediately drop by a huge margin. If you’re using this with a solar controller for example to charge a deep cycle battery like on a boat, you’ll get a maximum of 36 watts under 100% perfect conditions.Update Sept 8 2021: just got them paired to my solar generator and I have to say, not too happy. Probably going to return these. I have both hooked up in parallel and can’t get anywhere NEAR 140 watts combined. Both panels together can’t even hit the 70 watts each is rated for, with my bluetti sp200 at the exact same time of day I can easily pull 150 watts. Going to contact support it’s as if there are a bunch of broken connections within the panels, if I don’t have all of them deployed none of them work.I just got mine outside on a sunny day for the first time and hooked them up in parallel, have the 12v battery clamps hooked to a deep cycle battery and it seems to be putting out very high voltage, I’ve pictured my meter at 16.53 volts, it’s still climbing as I write this review. I’m not sure if this would be safe to leave on a battery unattended. It seems to have stabilized at 16.61 volts, on a fully charged deep cycle battery. I don’t know a whole lot about solar and batteries but again, seems high. My truck and other equipment charges at 14.7 volts.

Use the same cables for charging in the car in issues same with the battery packs. When unit has full sun, beautiful day it just randomly stops charging the battery packs or will only charge one. Purchased in late January decided to test before going camping this summer.Update: 4 months after purchasing unit the unit has died and will no longer supply power to any battery packs I have tried multiple cables from 6’ to 6” and 6 different brands of battery packs. Return window is closed for me but hopefully another doesn’t have to go through this.

Worked well for about 40-50 recharges of a mobile phone and a small power pack. Then today, it died on me right in the middle of charging a phone (all was going well until that moment). The main “power” indicator no longer lights up even in full sun. The company was really responsive and offered a replacement, which demonstrates confidence in their product. I will likely bring along a full power bank along with it in next off-grid outings, but I trust the panel should work well.

So I got the 70W folding charger and it’s quite compact and seems durable.I’m in ontario Canada, so I might not be getting full power? I’ve gotten 40 wats of the 70 on my jackery explorer 300.Been about 30 minutes in good sun and I’ve charged it 8%. Not too bad ?Definitely the best portable panel I’ve ever purchased, but im curious why I’m not seeing the full 60-70 watts? Could be because I’m in Canada.Still happy. 4.5/5 would recommend

I had high hopes for this panel. I liked the folded form factor and the great package of accessories. Delivery was in good condition. The unit seems to be well made. Two observations before we look at performance.1) The DC output port is protected by a soft flexible cap. To properly insert the DC cable connector, you must very gently pull out the flexible cap to extend the tiny lanyard. This moves the cap out of the way and allows connector to engage fully. Don’t pull too hard, this cap looks fragile. This is a good feature, so not a problem.2) The convenient carry size brings two disadvantages. The fabric seams between panels take a lot of surface area, which cannot hold solar cell area. In addition, the opened panels have no way to support them in a flat orientation toward the sun. You need to have a cardboard or other stiff FLAT material to place behind the panels and it must be supported to face EXACTLY at the 90 degree angle to the light from the sun. If you don’t observe this normal requirement for all solar panels, or if there is less than the brightest sun in the clearest sky, the X Dragon output is so low that the panels are nearly useless.I have a laboratory full of calibrated instruments and loads, so I was able to vary the DC load to find the power output at different currents under absolutely the best possible full sun conditions. Note that this only exists for about an hour on a perfect clear day with zero mist, haze, and of course no clouds. We have very bright sun in LA.The highest power I was able to record was 46.0 Watts measured at 16.8Volts and 2.74Amps. This required an extensive process of pointing the panels by attaching a stiff flat carboard backing AND manually tracking the sun angle to maximize the power output. I also had to vary the load to match the maximum power load point using a variable load resistor.Under all other conditions that a user would normally encounter 90% of the time, one or more of these constraints being less than optimal results in drastic loss of power from this panel. Typical outputs were between 10 Watts and 20 Watts for most of the 6 hour charging time on a bright day.Sadly, I had to return the Dragon panel. I replaced it with a Powerness SolarX S80 panel that is rigid, folds flat, has a Voltmeter and Ammeter display. It produced over 70 Watts immediately after an easy setup, did not require a cardboard backrest, and has its own rear stands built in. Power output was above 50Watts over a wide variety of non optimal conditions, making it user friendly and more tolerant of alignment, atmosphere, and sun angle.The other Dragon reviews at one and two stars for the Dragon confirm the low power output. When I compared the two products it was obvious that only one was properly advertised with a reasonable power rating. I will keep that one and enjoy the included Voltmeter and Ammeter feature.
