CamelCamelCamel.
wish they had 20kw portable solar.
Same seller at Big W marketplace - $59 on the 36W panel https://www.bigw.com.au/product/bigblue-portable-folding-sol…
Looks like different products
The pirate is referring to the 36 watt panel, which does look the same.

Thought this looked like a good deal and then I jumped on eBay - seems the prices have dropped dramatically.
Also I suspect there is a lot of overstating of outputs - a lot of panels look too physically small to be the outputs they claim
Correct. Listing and Reviews state only 45W PD Type-C and not 60w as per the title.
The Amazon one is 65cm X 53cm vs your eBay one 48cm X 18cm.
So completely different products
@10101010101: I am showing the eBay ones are nonsense output claims. It is impossible to get 100W with that size
However, the overall prices seem to have dropped a lot
@King Tightarse: I bought "300W" panel from ebay, size same as my Ecoflow 100W panel, and output is comparable, its a typical chi-tech with inflated tech specs
@radissimo: In the one I linked, they have dodged up a photoshopped picture it to suggest its hanging from a backback and a least 1m long.
Real size would be 'surprising' when it turned up in the mail
While the listing is not well written, in the images it does show the specific outputs of each USB port - including the 20V, 2.25A (45W) via USB-C.
The 60W will be the total output if using multiple ports. Which is how most USB chargers list wattage - the total overall, rather than the max from a single port. (and yes this is often annoying and misleading). In this case it may even technically be 60W PD, if it refers to PD spec 20V 2.25A and PD spec 5V 3A from the two USB-C ports.
I don't think they're being deliberately misleading, as in the second photo it states "Type C port: 20V 2.25A MAX" which equals 45W.
Or if you go to the third paragraph in "about this item" it repeatedly states that "1*45W Type-C Power Delivery."
BTW even though the deal has expired it's still 50% off, making it $75.
You are correct on the output, I ordered one from ebay. The output was less than 1/3rd of what was stated in the description and I tested in full sun. The other thing is, the panels have NO marking on them, meaning they don't state any expected output at all, which I'm sure is not necessarily legal for an electronic device.
It's also very very easy to damage the panels.
I complained and got a refund, then I was banned from all of their stores (there are a lot of stores that sell solar panels that are the same company on ebay).
In addition, there is some setting where if you get a refund, it can put a mark in the backend against your name, so many stores now, I cannot purchase presumably stores can exclude people for certain specific reasons.
Casinos can ban too successful gamblers. It's understandable if a store doesn't want to do business with anyone.
sounds like they did you a favour banning you… save your bucks for a better seller!
Which model did you have? The 36w?
Also one review stated that it drained a battery instead of charging in cloudy conditions. A simple diode would save that - bizarre that its missing, if correct
This one?
From 5% it went to zero in enclosed woods after 4 p.m. to 5 p.m. on a cloudy but very sunny day , so basically it CAN drain the power of small generators completely instead of charging them if only at 5 % or lower in a highly wooded area
Prob safe to ignore that review as user error. I suspect the 5% loss is just self drain from the Anker 511 staying awake with no power coming in because they were trying to use the solar panel in enclosed woods.
No way for a solar panel to drain the 511 if using the DC input. If plugged in via USB-C then to drain the power bank, the charge circuit on the solar panel would have to be able to negotiate for the 511 to output power. Seems unlikely they'd use a much more expensive two way charge circuit for the solar panel when it only ever needs to output power!
Yes that was it
Cheers OP :)
Are they good for camping
I'm no camping expert, but I think there are better tents available.
Very uncomfortable to sleep on
bad. Takes ages to start a fire
no, they're shocking
For anyone considering, the unfolded size is 179.83 x 41.91 x 3.05 centimeters
Yep, which is big enough to provide the 100W as claimed.
The cells are probably not amazing but it's relatively cheap for a 100W folding solar panel with 45W USB-C 20V output.
If you add in Amazon’s fees, the selling price is below cost.
Seems like OOS
Edit. Able to put in cart now. Thanks Op
Any good deals on power stations to pair this with?
I know jaycar usually have specials on. Cannot vouch for quality.
I noted this previous deal: https://www.ozbargain.com.au/node/841506 VTOMAN Jump 600X 299Wh 600W (1200W Surge) LiFePO4 Portable Power Station $303.99 Shipped @ Vtoman eBay AU. It has an Ebay Plus 25% off code (CBTFY25) which makes it slightly cheaper again. New record low price? Comments seem mixed about quality. Or the larger model is cheaper too with Ebay Plus: https://www.ebay.com.au/itm/354927536901
Thanks
I had read the feedback and thought it’s above my good deal vs sketchy feedback threshold
https://www.ozbargain.com.au/comment/15173832/redir
Gotta admit, whilst I like this, I find I rarely find an opportunity to use it. I do a lot of camping, but I always have a power bank that lasts and that I can charge when driving. It is too bulky for multiple day hikes or bikepacking
When do you guys use it? Maybe I'm just not a big power user
Solar panels aren't designed for hiking - you really only need it when you're onsite for a decent term and have something with a power draw like a 12v fridge.
Nowadays with LEDs and portable power banks it's so much easier to keep up with power needs, but there definitely is a market at the more established campsites for panels. I've only used mine a couple of times too.
Thanks for the reply.
Yeah I guess I have always been looking how I could use these, yet nothing fits in my category.
I don't have a fridge and I rarely stay in any place for an extended period.
I have smaller, outdated version which I did get for extended backpacking and hiking but when you are on the move all day it kind of was never applicable
Makes good sense tho for other uses
cheers
Would this be good enough to trickle charge a 100AH battery when camping? The 100AH battery is just powering the 12v fridge and i have anxiety of it going below 20% when camping more than 2-3 days
You've pretty much described the exact use case for these. At a constant 100W you will charge a 100ah battery in around 9h.
seems like a good price so I got one
Tempted but i still.havent used my kmart $60 panel i got 2 or so years ago.
Wonder if anyone has feedback on it?
Really need to get out more.
They look big enough to produce 100w, fingers crossed, ordered 3
Nice. Gonna need this on a survival island trip
I got one - not that I do much camping, but at least when the apocalypse comes I'll be able to charge my 'phone and stare at the 'no service' message whilst I slowly starve.
Download Wikipedia and a survival manual to your phone.
And your favourite books.
There. Phone still useful in apocalypse.
True. Can also play the offline dinosaur game on Chrome whilst waiting for the stun gun I use (to fend off the zombie hordes) to recharge.
Showing a slight increase now $67.97
Did I miss something the output of this solar mat is unregulated, so you would need a Solar controller to regulate the up to 18 volt output down to something around 14.5 volts to use it to charge lead acid or gel batteries, if I’m not mistaken.
Same questions here. For this solar panel, would you need a solar controller to charge a battery? Would like to know as well. Thanks
From a quick look through one of the pictures, there's a built-in chip controller outputting 12V-18V.
Offer seems to be over on the 100w panels, back to full price… :(
They put them back in stock and same price with 50% coupon.
Agree but so many complaints in reviews make this a pass even with reduction.
How long to charge a tesla with this
Back on at 50% off but $74.97 now
Anyone receive and tested its true 100watt or close
Received the 3 I ordered today, earlier than expected. Its cloudy in Melbourne today but was getting 65 to 70w, which is pretty good. Hopefully will get 100w when it's sunny.
There are several usb connections and a nominal 18v output which is unregulated and appears to be direct from the panels. 22voc and 18v max power.
Confirm they hit 100w in direct sun 👍
Complete noob here, Can I charge my car battery with this solar panels and the cables supplied?
Also, any cheap way to find out how much watt is it outputting?
Thanks.
I also received it. The output limit should be integrated on the panel. The seller should modify the product description. I am generally satisfied with the price. The unfolded size is very large, enough for it to reach 100W.
Got it delivered over the weekend. It is outputting as spec. On an early Sunday Melbourne morning, it was already outputting 95W. It seems to go on sale every other day, but price is now at least $75 (with 50% off coupon).
This is very promising. Sorry for the noob question but how are you measuring this?
I've got it hooked up to a solar power station, specifically a VTOMAN FlashSpeed 1500. It can measure how much power its being recharged with. Also, as a side experiment, I tried using this inside the house, with the solar panels facing where the sun should generally be. Again, this was very, very, sub-optimal, yet it was pulling in 95W. It was doing a much better job compared to the two "300W" panels bought from eBay, connected in series, that are outside the house, pulling in between 20W to 120W today, depending on cloud cover.
Do I need a solar regulator to connect this to a battery?
Do I need to get an MPPT for this?
How are people connecting their mppt to this?
Yeah would like to know too. It has some dc plug into xt60 plug. I think we need dc plug to those ring terminal but I can’t anywhere that sells it
Does it put out enough volts for an mppt? I think the Victron wants more than 18v to work reliably
According to my research, minimum needs to be vbat + 5v. So if the battery is 13v, it should meet the minimum requirements but as you said more than 18v is ideal. So does that mean i need to get another batch of these panels and if so, how do i go about connecting it in series to double the panel voltage?
Yes connecting two sets together to create 36v would work. I think 18v is a bit too close for an MPPT to work properly.
You could just use the more basic PWM style - less efficient but it would work with 18v panels
@King Tightarse: I wished I did more research on this before going ahead and buying an expensive MPPT lol
Reason for the MPPT is because i heard it has to have a lifepo4 charging profile otherwise it will damage the battery if not regulated properly.
For this particular panel, the output looks to be DC 5.5mmx2.1mm so how do i go about putting it in series? Damn what an expensive project this is turning out to be
@No Child Support: I am just learning myself, so please take my ideas with a grain of salt. Others will definitely know more.
Series and parallel are pretty easy - Google will show it better examples than I can say here.
I am sure you will be able to use that MPPT later or flip it on Bay
Cheers
