Ecosonique 30W Foldable Solar Panel with 20000 mAh Power Bank 33W Fast Charging Portable Charger with Built-in Cable ETFE Solar Panel Charger DC12V USB A QC 3.0 USB C for Cellphone Camping Travel

I just got this yesterday, but I have had time to test it and check it out. It is exactly as described and works perfect! I have larger panels and very large battery packs that can power refrigerators and TVs. This would not be able to do that, but to get your tablets and cell phones charged, this is just the ticket. Since I output USB direct to most common items like battery chargers that are 10000 to 38000 mAh almost anything including cell phones can hook up direct to the Solar Panel. I can even charge my other 10 or so batteries as well. If you are good with the cable types, you can do 2 at a time but it does slow the overall charge time when you do this. I get about 28 watts in Arizona direct sunlight, and I tilted the panel to face the sun most directly. My pictures show this, I just did a makeshift prop up job.One problem reported was the charger shuts off after 1 minute when charging. No. That does not happen, and I checked it out and charged for hours and it never shut off. I think people say it turns off because in the bright sun you can't see the LED numbers and initially the numbers are bright but then dim to save power. So, the battery blinks the first percentage number to indicate it is charging. A single percent takes about 8 minutes, so it takes most of the day to charge from 1% -100%. If you do the math 8 minutes per percentage point means a 90% charge would take 12 hours. So be prepared for it to take a long time. I bet you are glad you didn't buy a 10 watt panel now! (See attached pictures.)

Handy solar charger unit that comes with a 20,000 mah powerbank. Great for traveling and the outdoors, and includes several cords needed for charging items using the unit. We tested it and kept it open in the window but we haven’t had very strong rays lately, so the charging was slow. I look forward to trying it as the weather improves. The design is travel friendly, with carabiners to assist with hanging it to catch sun rays.

This set, panel and bank, is really nice when outside not near outlets for a decent time period to keep your USB items charged up. The solar charger does a decent job keeping the bank recharged so you can keep going with the items using the bank, but it does charge slow and you need to make sure you face the panels towards the sun for the best results, it will charge faster doing that and depending on how drained the bank is you could have a full bank just following the sun or setting them out right when the sun appears without having to move them. Don't use them during rain or get them wet, which the instructions say.. which is kinda common sense but I wish the panel was able to get wet cause I could leave that out and protect the bank.. but there isn't much sun during rain anyway. The bank itself charges things at a decent speed and does a decent job charging your devices (at least phones) while using as well instead of just keeping at a level % like some others I've used.

Power bank has C cable and an iPhone cable... I dont need iPhone cable's

This is my second battery with solar charger. I have another brand with a similar setup. The battery is compact and easy to carry. Comes with USB-C (most common now) and the older USB and Apple connection. Took me a bit to figure out which connection goes to the charger and panels.The instructions indicate to avoid getting the panels and battery wet. I let the panels outside over night while attached to the battery. The battery was kept in the panel's carry case.The panels then remained outdoors pointed at the sun the entire morning until the sun past the house (east to west) and the battery was completely charged.I would not submerge or leave the panels outdoors during rain, but they performed well with night time condensation as did the battery.The panels MUST be aimed at the sun, there HAS to be sun, so, no sun, no charge.I would use this as a hiking battery and panel easily. The panels could strap to a back pack with the battery inside charging. of course if this is in wooded area, then just tuck it away.I am unsure about charging time. The battery arrived with about 65% charge and 3PM was 100%. I don't think that is so abnormal, as my older battery and panel performed the similarly.

I recently bought the 30w panel and they worked great for 6 weeks until one day they just stopped working. They hadnt got wet or been dropped, so i was pretty down about it.But, after reaching out to Ecosonique I was quickly sent a brand new one free of charge. Emily from Eco was very prompt and helpful. They honored their 12 month guarantee but unfortunately exactly 6 weeks plus a day later - today April 16th - the new panels did the exact same thing.Keep in mind that as a traveler i use them daily, however tell that to my 10 year old Anker 14w back up panels that still go strong to this day.I do like ecosonique but they arent built to last. I would not give them your money. The difference between panels that last years vs ecosonique products is vast. They are scamming the public like so many "upstart" companies do. It really bugs me when people sacrifice trust for profit.

The battery seems great, but the panels only charged my Apple Watch up 8% with maybe five hours of charging in full sun. Definitely not worth carrying on a hike. Maybe I just got a bad one.

Got this to charge devices while we are at our family cabin in the mountain. We have a solar system on the cabin and its important for us to save energy where possible. This is great to put out on the porch while we are inside chatting or playing board games and works great to charge up our devices without draining the cabin battery system.
