Review: works great with the right inverter - As someone who loves spending days off-grid, I was looking for a reliable source of renewable energy. This solar panel kit has delivered beyond my expectations. When I first unpacked the kit, I was pleasantly surprised by how lightweight and foldable it was—perfect for throwing in my backpack or car without taking up too much space. The setup was incredibly straightforward; I simply unfolded the panels, positioned them to catch the sun, and connected my devices. It felt almost too easy! On a recent four-day camping trip, I had the chance to put it to the test. Each morning, I set up the panels next to my tent, and by noon, I was able to fully charge my portable power station. This meant that I had enough energy to keep my phone charged for navigation, power my laptop for a little work, and even keep a small cooler running to store food. It was fantastic not having to worry about running out of battery. One evening, I decided to try charging my lights for the campsite. Because of the DOKIO kit's efficiency, I had all the power I needed by sunset. I could bask in the glow of my solar-powered lights without fearing I’d drain my resources. The durability of the panel kit also stood out. It withstood a slight drizzle one day and still performed beautifully without any issues
Review: Works as expected, right out of the box. - I received the solar kit last night and tested it out from 4PM to 5PM this afternoon when there were about 3 hours of sunlight before the sky went overcast again. The solar panels were directly connected to an Ecoflow power station. The highest solar power that I saw was displayed on my power station was 118W. The highest solar power that I saw was displayed on my iPhone was 113W. The test continued until the power station stopped charging at 100%. The test confirmed this solar kit worked as expected, right out of the box. - Biggest pro: easy to carry and easy to use. - Biggest con: no kickstand or equivalent!! - Confirmed: peak power can reach 118W - Unknown: durability One thing that deserves extra attention: just as demonstrated in 1 of the product videos posted here at desertcart, this kit's solar output is *very* sensitive to how the panels are positioned against the sun. Simply by walking from one side of the panels to the other side, briefly casting a small shadow on the panels, I saw the solar power reported on my iPhone drop from 100+ to lower than 60W immediately and then bounce back. I think this is a good buy. Much more portable than my heavy Ecoflow solar panels. I plan to permanently leave them in my car.

## 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 the 300W foldable panel, separate controller, SAE/XT60/Alligator clips, DC5521/5525/35135/6440 adapters, 9.85ft cable, storage bag, and manual—a one-stop kit for camping, RVing, 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.

### ⭐⭐⭐⭐ Lightweight and This works way better than I expected.
*by D***E on July 14, 2025*

This is a great lightweight kit. You can throw it in the trunk or back seat. I get enough voltage and amps to charge my 100aH LifePo4 battery with just 2 panels exposed to the sun even in low light. Something not mentioned but is an important feature, the controller has cross polarity protection and corrects if you plug in something not correctly polarized. I would have gave 5 stars except for 3 small things. The controller is a little hard to operate, the SAE plug is very loose and falls out easy, I had to buy a new cable to replace the Original. And it would have been nice to have grommets along the edges to hang from a rope or hooks on a tree or wall. This works way better than I expected.
