## Description

DOKIO 300W Portable Foldable Solar Panel Kit (19.3x37.4in, 15.2lb), with Separate Controller and Dual USB, Monocrystalline Charger for 12V Batteries, Power Stations, RV Camping Emergency Use

## Features

- 【BIG POWER, STILL PORTABLE】 Folds to 19.3×37.4×1.1in and weighs only 15.2lb, so this 300W panel packs serious energy yet remains slim and easy to move, mount, or store for RVs, vans, boats, and backup use.
- 【SEPARATE CONTROLLER FOR SAFER CHARGING】 Equipped with a standalone PWM controller that protects your 12V system from reverse polarity, overcharge, overload, and short-circuit—and can be replaced or upgraded later if needed.
- 【LONG REACH FOR FLEXIBLE SETUP】 Includes a 9.85ft (3m) cable, allowing you to place the panel in full sunlight while keeping the controller or power station safely shaded for cooler, safer operation.
- 【KNOW YOUR POWER STATION’S LIMITS】 Some power stations restrict solar input (often 100-200W). Even under full sun, a 300W panel cannot exceed your unit’s own cap—this is normal design, not a defect. Please check your model or message us for confirmation before ordering.
- 【USB CHARGING WHEN YOU NEED IT】 When connected to a 12V battery, the dual USB ports provide stable power for phones, lights, and small devices. Even without a battery, they can still work in sunlight for emergency top-ups, though current may fluctuate.
- 【MONOCRYSTALLINE EFFICIENCY, BUILT FOR OUTDOORS】 High-grade mono cells deliver better conversion efficiency and reduce mismatch loss. The panel surface is weather-resistant, but avoid leaving the fabric case in heavy rain or strong sun for days to extend life.
- 【COMPLETE BUNDLE, READY TO GO】 Includes 300W foldable panel, standalone controller, SAE/XT60/alligator clips, 4 DC adapters (3.5×1.35mm / 5.5×2.1mm / 5.5×2.5mm / 8.0mm), 9.8ft cable, storage bag, and manual—a one-stop kit for camping, RV trips, or emergency backup.

## Questions & Answers

**Q: Is the solar charge controller compatible with "LiFePo4 chemistry" batteries?**
A: Yes, but it depends on your battery setup. the DOKIO charge controller included with the 200W foldable solar panel kit can be configured for LIFEPO4 batteries (battery setting B03).  But, the manual only describes usage for a 12V LIFEPO4 12v 4s setup (4s = 4 cells at 3.2V each, 12.8 volts in series).   This is a solid little 4-stage PWM (Pulse Width Modulation) charge controller.  PWM charge controllers typically run 80% efficient.  It is free with the panels so it costs you nothing to determine if it meets your needs.  The more expensive MPPT charge controllers typically run >95% efficient so if maximizing the amount of usable power from your panels is important you will want to upgrade to an MPPT controller at some point.   

 

DOKIO charge controller details:

12v 20Amp
2 USB ports (5v max 2A) that can be used without battery attached
3 battery type settings B01, B02, B03
Lead-Acid
Setting B01 = charges at 13.7V
Low Volt cutoff = 10.7V
Low Volt reconnect 12.6V
Lithium Ion 3s (3 x 3.7 V = 11.1V)
Setting B02 = charges at 12.6V
Low volt cutoff = 9.0V
Low volt reconnect = 10.5V
LIFEPO4 4s (3 x 3.2V = 12.8V)
Setting B03 = charges at 14.6V
Low volt disconnect 10.0V
Low volt reconnect 12.0V
 

PWM vs MPPT Efficiency comparison (eg: panels generating 17.7V x 9.2A = 163 watts)

PWM controller 80%, 163watts x .8 = 130watts usable
MPPT controller 95%, 163watts = 155watts usable

**Q: Can i charge lithium batteries?**
A: Yes. Mine puts out about 15 amps max

**Q: Is it plug compatible with any portable generators?**
A: SAE connectors aren’t great, 10AWG is small dia, but the included XT60 can connect to many “solar generators” (including AC200 from Bluetti) which are more-accurately called “power stations”. Review by Bob Wells is laudatory. More than enough “adaptors” included.....

**Q: Can this be connected directly to a solar generator?**
A: The panels are connected to the controller with SAE (2 flat). If you are looking to directly connect them to a portable generator, you will need to purchase an adaptor.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Dokio 300W Portable Panels
*by E***O on April 23, 2024*

The media could not be loaded. ****Update 4/30/24I requested a replacement. Amazon sent me new panels. The seller also reached out to me. Panels were delivered the next day and so far they work great. They charge my Lifep04 100Ah battery and I can run the camper AC on a sunny day with no problem while keeping the battery charged.Update****Solar panel burned after the second time charging a 12V LifeP04 battery 100AH and a 2500W load....See last picture. I ordered a replacement will update when I get it and see how long it lasts...************Not bad, they are easy to move around. No back legs to hold them upright. No holes to hang them from a wall. The Controller is not the best, but a better one to take advantage of the panels.Tested them for an hour, battery went from 11.9 to 12.6 V within 30 minutes on a cloudy day. I haven't tested this panel fully yet. Not bad for the price I paid.The connections are simple, however I had a reverse polarity within the system and I had to switch my battery cables in order to make it work. No a good thing that's why they send you an adapter. Quality seems good, they are flexible however don't bend them to much or they will crack. Cables are short, order extra cables....

### ⭐⭐⭐⭐⭐ Powering Up My Pop-Up Trailer with Solar Energy
*by N***S on June 23, 2025*

I gotta tell you, I decided to level up my pop-up trailer game by adding two 6v golf cart batteries and a solar panel. So, picture this: I slap the panel on the roof before popping up the trailer, and bam! It's like magic - all hooked up to my batteries and ready to roll. Let me just say, it's been about four days since I've been using this setup, and let me tell you, it's working like a charm. Plus, a sweet bonus is that it charges my Jackery like a boss. Totally worth it, highly recommend!

### ⭐⭐⭐⭐ 1.5 year update
*by K***R on February 13, 2022*

UPDATE! My original review follows. I am pretty happy with this solar setup. I am NOT into comparing specs or having the latest and greatest, etc.. I have owned this setup for over 1.5 years and use to power my 26 foot trailer with 2 cheap Walmart 70ah batts. I use the toy-like controller included. I camp pretty frequently and would say I've used the panels for 3 months combined days. I am ok with the setup as it is affordable, flexible, easy. My past 45 lb setup with hard frame got to be a chore. These charge my batts within a couple hours in good sunI recharge daily. Panels could use an uptick on ruggedness. And grommets, attachment points so you can hold them in place. Laying on ground is often dirty/dusty, standing flexible panels in wind, not so good. You can build a frame, I just haven't. If you're looking to spend little and want decent capability, these are worth a try. If they last me another 1.5 years (for a total of 3) $300 bucks total, not bad. I think they will last longer if cared for.Original review. Just bought this and used for three days. Delivered as expected. Safe packaging. The panels seem of good quality, though I can see what others have mentioned about possibility of material holding panels breaking down. The photos in the advertising are misleading: these panels will NOT stand up flat like that without considerable support behind them. Support you will pay another $50 to $100 to build (unless you're very crafty) They bend very easily and care is necessary. I plan to take this inside during inclement weather, even wind. I have 2 cheap lead acid batteries that had run out of power the night before due to furnace use in cold weather. These panels charged those batteries fast, and my heat lasted through the night next night. I had a hard framed heavy Zamp 200 watt suitcase a few years ago and to compare I'd say this was considerably faster. I don't measure amps, all that stuff. I want to plug it in and get back to what I'm doing for fun. And there's my single largest disappointment with this package... oddly, Dokio failed to include a cable with the XT60 connector for their controller and an SAE connector for the port on the side of probably 3 million travel trailers out there, like mine. I'm no pro, and so maybe I am missing something... but who wants to take their battery covers off and clamp the controller to the battery each time they want to charge (often more than once a day...)? I really want that cable, say 10 to 12 feet in length, to make this easier for my style of use. The PWM controller that came with this unit is pretty fragile looking too, but it seems to work and I wanted to use the kit as is for awhile. Anyway, for the money, this kit is a go, so far. I hope it lasts a few years.
