The ALLPOWERS SP037 has a hidden feature. VALUE FOR MONEY. Roughly half the price of the equivalent ECOFLOW solar panels with the same output. In fact I am using the SP037 to power up an EcoFlow Delta 2 Max. If ALLPOWERS had a LiFePO version of their power station I would have been in all in ALLPOWERS. Delivery was quick and the items arrived safely. Secretly, I like ALLPOWERS so much that I am thinking about partnering with ALLPOWERS to showcase their gear. I am going fully off grid with a mobile car camping trip and a test bed for digital nomad tech. Starlink mini. But also composing music in the wild with ALLPOWER and conducting cyber crime investigations in the field powered by ALLPOWERS.
Fits, works, fit for purpose
All items I have purchased are amazing and the quality of the products are second to none. The pricing was much better than other products. The service / delivery of items was quick with no problems.
Pretty good product and charges the power box quite well. Haven't achieved 400watts input for charging, but variables like bad solar panel angles, weather conditions may have affected it.
.
the 140W 4x foldable panel is quite convenient to carry, and to use. We need it only to trickle charge - if you wanted more, you'd have to look at the bulkier 200 or 400W units, but we felt they were too big for us to handle. The solar connector cable does have an interesting yellow 2 pole plug on it (spec unknown - would like to find out!).
Great, easy to set up ,charges even when shady,excellent.
Excellent value
The portable solar panel is a good on the go solar panel however the power cable from inside the bag on the solar panels are not long enough. I wish the power cable were at least 1m long as connecting two solar panels together is a mission. I don’t think it would work with three solar panels together.
Quick and easy
Nice big solar panels, but would like to see a 45 degree support for this one.
Very happy to finally own a set of Solar Panels that actually deliver. Was getting 310 to 320 watts on a cloudy\sunny day. Great delivery process too so thanks.
Very good service. quick postage and the panel works very well, charged my R600 in about 6 hours.
Great package deal with the R1500
Ordered this solar panel, surprisingly came within just a few days!! Haven't used it yet, but it looks nice and sturdy, nice carry case, will be great for camping and recharging the allpower battery box I also bought - and at a good price!
Awesome just what I needed
all powers products are great.
I bought it to run my 40l fridge overnight and it lasted until the next day. At 15:00 it had 40% battery left and started the day before at 17:30. So yeah I'm very satisfied with this product.
An essential addition to our battery.🪫
I haven't had the chance to use it yet, but considering the quality of your products, I think everything will be fine.
Purchased to compliment the AP battery pack and I could not be happier. Packaged very well and easy to use.
Pros: - Best value in terms of portable solar panels you can find. You won't find a better price per watt for portable panels. - Durable, but must be lightly cleaned every so often. - Fast shipping! Got here the next day on the weekend. - AllPowers support has been very helpful when assistance is needed. Cons: - The threads around the panels to hook them onto things isn't very durable. - The stands/legs only allow limited adjustment, you're unable to get a low slope in which a big chunk of the year is better to keep them flat. It's disappointing given the lack of additional airflow which can affect performance.
Running my new Ecoflow Delta Pro along with the additional battery, and a simulated power outage load, the two 400 watt panels were not close to being able to bring the generator to full charge; 60%. I live in the desert and the sun conditions were ideal, plus I angled the panels frequently with the suns movement. I added the 600 watt AllPowers flexible panel not knowing how I should position it. I initially had it laying on the ground flat. Without moving it with the sun, the input wattage over doubled and my generator and battery were at 100% charge before noon, for the two days that I tested it. I am very pleased with the results received from this AllPowers 600 watt panel and am certainly happy with my purchase!
Very pleased did not generate 600 watts only hit 380 but it was solid and 380 is still good. Easy to set up and use. Put it flat on the ground but complete sun
This was the best purchase I'm gonna be getting another one. I averaged at least 400 watts. Nice job. Great price
