BigBlue 150W Portable Solar Panels with Kickstands, IP68 Waterproof Solar Charger with MC-4/XT60 for Power Station, 25% Conversion Efficiency, Camping Essentials, Foldable Solar Panel for RV Life

All the following items, used in this review, were purchased on Amazon: BigBlue SolarPowa 30 Folding Solar Charger (Smart IC Chip Charging Controller), JSAUX 100-watt USB-C to USB-C Cable (6-ft length), Portable Power Bank PB-08 PD22.5W (20Ah @ 3.7V) (74Wh), and a Toptes TS-710 Digital Light Meter. Local Weather Conditions on June 14, 2024 (3:15pm to 5:15pm): Clear skies, 95° F (35° C), Relative Humidity 40%, and a light breeze from the west. Digital Light Meter reading (averaged) taken at the beginning of, and during, the solar charging process: 148,000 Lux (13749.6499 Foot Candles). I drained my 20Ah power bank to a DoD (Depth of Discharge) of 65% for this test, with just 35% of the power bank capacity remaining. Once I had the solar panel set up and perpendicular to the sun, I connected the battery pack at 3:15pm. The power bank immediately recognized the input connection and started the charging process. From time to time, I would re-adjust the solar panel, to ensure that it stayed close to perpendicular to the sun. To compensate for the heat of the day, I placed the solar panel on the grass and I kept the power bank on the shaded, cool, concrete/stone walkway. At 5:15pm, exactly 2 hours later, my power bank hit 100% and charging stopped. Footprint Hero's Solar Charge Time Calculator predicted 2.1 hours of “peak sun” would be needed to charge a 20Ah power bank from 35% back up to 100%, using a 30-watt solar panel and a very efficient MPPT solar charge controller. Based on my own observations and test results, it would seem that the SolarPowa 30's Smart IC Chip charge controller is on par with the performance characteristics of a MPPT controller, at least in a “Full Sun” scenario. YMMV. **Full Disclosure: I have NO financial interest in BigBlue Energy (HK) Limited (investments, employment, paid-endorsements, etc) and I paid for this solar charger, along with all the other items in this review, with my own money. Overall, I am very satified with my purchase. I look forward to getting many years of trouble-free service from this solar charger, especially when my wife and I are out camping and need a dependable way to charge our battery banks and other rechargeable camping equipment.

Bought two 400W Big Blue solar panels for charging Jackery 2000 Plus (Jackery over-charges IMO for their 200W panels and connectors, got these for basically the same price with double wattage but also had to purchase MC4-to-DC8mm (DC7909) adapters and also DC7909-to-DC8020 adapters for the Jackery 2000 Plus; not including any extension cables). Just ran my first test with both panels plugged in. With clear skies under a September AZ sun @ 96 F around 1:30 PM got an initial 628W incoming charge, but soon leveled off at 590-600W for the next hour. Not as high as I hoped, but higher temps do tend to reduce solar panel efficiency and I also had 20-ft extension cables (DC8mm 14 AWG) so it’s possible that sucked up some wattage. Two weeks ago when I tested just one solar panel I got an initial 349W incoming charge which tells me these panels can perform close to their stated wattage. Overall performs decently well and cost less than if purchasing Jackery’s equipment. Longevity of setup TBD. In researching there are some concerns about how much wattage can safely be passed through a DC7909 connector (which is why I suspect Jackery upgraded to the DC8020 connector with their larger solar power units that will accept charge from multiple solar panels chained together). However I couldn’t find any adapters that were directly MC4-to-DC8020 so for the meantime I have extra DC7909-to-DC8029 adapters just in case.

Hasn't worked yet not extremely happy.

In January (2024) I made my my second BigBlue purchase. I have an older 28w that has been through super hot summers and extremely cold winters but is still working very well. I picked this up as an upgrade for one of my "small" panels. Within a couple of months after receiving this "Upgraded" 30w panel, it stopped charging devices properly. I ordered a second one in July while I spent time figuring out if the issue was the panel or my array of cables. I eventually contacted support regarding my original 30w and after a short exchange back and forth they sent me a replacement. It arrived very quickly and I couldn't be happier! As a home user, I have a system of swapping battery packs to keep my other devices constantly charged. Having a velcroed stand attached to the back of the panel makes it easy to keep the panels pointed toward the sun and rotate/move them as needed throughout the day. With USB-C to USB-C fast charging things are done a lot faster than on the 28w's USB-A ports. This has been a great upgrade and I use my three BigBlue panels almost every day. I don't know what happened to my first purchase, but with a two-year warranty, it's comforting to know that I can reach out to them if I have any future problems.

Before purchasing this, I found online reviews warning the Chinese solar panels only produce half their rated power at best. So, I bought one rated for at least twice my actual needs. So, yes, it can put out up to 20W+ in the middle of a bright sunny day when aimed properly at the sun. I can accept that. However, that's not its biggest deficit. I have no interest in the USB outputs since I'm only using the 19V output to a separate, RF quiet, solar charge controller. The built-in solar controller is the cheapest one the manufacturer could get their hands on. It seems to emit more RF energy into the air than it passes on to the 19V output. In fact, it emits so much RF noise all over the radio spectrum it's a wonder the FCC doesn't ban the sale of them. Unfortunately, the built-in solar controller for the USB charge ports cannot be bypassed. In fact, you'd have to do irreversible damage to the plastic case around the built-in controller in order to open it up. I'm returning it. I'm especially disappointed because I was counting on using this solar panel very soon for a ham radio expedition.

Good product

preso per sopperire mancanza di rete elettrica in una baita usata saltuariamente, carica senza problemi cellulari e altre apparecchiature elettroniche ma l'abbiamo usato anche per ricaricare delle batterie al piombo a 12 volt! fa ottimamente il suo dovere non e' piccolissimo ma si ripiega in forma di una piccola valigetta, ed e' completo di vari adattatori

Highly recommend this product. Had the smaller version and liked it so much that I bumped up to the larger model.

Wie man auf dem Bilder sehen kann hat die top Solar mehr Leistung gebracht obwohl die top Solar Panel kleiner und leichter ist fast 1000 Gramm Unterschied! Angeschlossen mit EcoFlow River Max Powerstation Getestet unter den gleichen Bedingungen

It was a big disappointment. The product description says nominal output is 63 Watts. I didn't expect it to be that high, because vendors usually exaggerate that number. But the output was just 14 Watts, and that was in Toronto at the beginning of August at 1 PM on very sunny day. Can't imaging better conditions. Another reason for disappointment is that I have another panel from the same vendor which is rated 28 Watts. That panel was positioned next to this one and produced 12 Watts. It looks like the vendor is labeling their products pretty randomly. They just put a number and double the price. The wattage rating has no connection to the actual output that you can get from the panel. And the actual output is far less than any number that they advertise. I can buy decent solar panel with 12 Watts output for the fraction of price that this vendor charge.
