About this item
- 30000mAh Large Capacity Power Bank: Compatible with Apple, Samsung, ipad, airpods and other electronic devices. After professional testing, 30000mAh is enough to charge iPhone 13 6.5 times, Galaxy S21 7.5 times, and iPad Pro 2020 3 times.
- 10W Wireless Charging: We have added a wireless charging function to the solar power bank, which is suitable for all devices that support QI, such as iPhone 13/12/SE/XR/XR MAX/XS/X/ 11/ 8plus, Samsung Galaxy Z Fold3/S21+/S20/A52/F52, etc.
- 18W Fast Charging Power Bank: Controlled by a smart chip, the charging speed is almost three times that of ordinary chargers. Chip control can effectively avoid overcurrent, overvoltage, overload, short circuit and other phenomena to cause damage to the mobile phone.
- Perfect for Outdoor Use: Solar cell phone charger is made of ABS+PC+silicone material, with compass and dual LED flashlight, perfect for camping, cycling, fishing, traveling, beach, etc.
- Warm Tips: Please kindly know that solar charging is an additional feature. Due to the small panel size, large capacity and uncontrollable sunlight intensity into consideration, the solar charging option works as a backup solution when other sources of power are unavailable. Make sure the power bank is fully charged before your trips.

- Reviewed in the United States on July 17, 2024Every few months, I pull this out of my glove box to give it a boost so I know it's charged if I need it. The power bank is retaining its charge amazingly well! It hardly needs any boosting at all!
Yes, it's kinda hefty and yes, it needs to be charged up for use. The solar panel is to keep the battery from draining too quickly. So many ports! Charge multiple items. Lost a cable? It has spot charging as well. I haven't needed the flashlight, but it seems plenty bright when I've tried it out.
- Reviewed in the United States on August 8, 2021I loved this charger. I got it on time, and I was VERY impressed by one thing above all at a first glance… the durability. It feels like you can drive over this thing with a tank and still use it afterwards. I have only had it for a few days, but in order to test the battery life, I fully charged it, and let it see how long it could charge a device. It was able to charge my iPhone XR 5 times before it ran out of juice. That is slightly under the 7 times advertised, but I was also using my phone the entire time, so I was draining battery too. For me, charging power is excellent. In terms of battery life, it meets my expectations. The lights on it are cool, plus they are a good indication on if it is solar charging or not.
I am a more tech savvy person, and have bought dozens of items like this in the past. This one is currently my favorite. The one I liked before this was a deal from Costco for 2 portable charges for around the same price… the Costco deal is FAR worse than this. This product is everything you could want in a charger. Honestly, other than the addition of a higher quality USB C cable, there aren’t any ways I can think of that make this product much better.
Overall, amazing product 10/10 would recommend to any consumer or friend looking for a high grade heavy duty charger. Well done Ryoko.
- Reviewed in the United States on July 24, 2021I bought this to enable me to charge my phone on a 12 day backpacking trip. I charged it both via wall power and solar power at home twice before packing. Once i got on the trail, no amount of direct (no cloud, no movement) sunlight would charge this charger. I used up the charge it had from wall power two days into my backpacking trek and then it was just a paper weight for the next 10 days, One of of my co-backpackers had the same device purchased at the same time and had the same issue. Really disappointed, missed many photo ops from my trip as my camera was dead and i could not charge.
Edit as of 8/11/21 Seller reached out to me and sent me a new unit. The new unit does charge via solar power. Great example of standing by your product and proactively taking care of their customer. Thank you for the great service!
- Reviewed in the United States on July 30, 2021I tested this powerbank along with a Belkin brand that’s 20k mah and double the price and this one doubled the time. I honestly thought it was going to be about the same time for both but I was wrong. Finds like these is what keeps me trusting new brands. It holds the charge really well, I have been using it along with the other one in cycles and this gives me about 3 days of back and forth charging my phone and a remote I need to carry with me. The charged is very rugged and the wireless charging feature works as expected, it took me a while to find the sweet spot where it doesn’t disconnect and in case you are wondering how to use it: press the on button once, the lights will flash, wait for the solid green light and just align your phone with the bottom frame line and voila! That’s the sweet spot. This is an amazing charger for the price. Totally happy with my purchase!
- Reviewed in the United States on March 14, 2022If you buy this, buy it for the battery - the ability to charge the battery from a plug and then use it to charge your phone, tablet, etc. It seems to work well for that.
The solar charging is lacking. The user manual says "Or expose the solar panel under the sunshine, ONLY recommended in emergency condition. In this case the battery will be fully charged in at least a week." So you would need to be in a pretty dire emergency to rely on the solar charging.
And, as least on my unit, the compass doesn't work at all. It doesn't turn as you move the battery. The flashlight works, but isn't very strong.
- Reviewed in the United States on May 16, 2023I would like to say this is one of my best purchases I have ever made!!! I absolutely love it and it charges my phone up to three days I mess off and on it’s solar powered you can also charge it!!! I definitely recommend getting this. It is a little heavy, but it works great. And it even has a flashlight.
- Reviewed in the United States on January 17, 2022Other reviewers claim the solar power function works beautifully. This was not my case. It has never worked. The green light on the solar panel does turn on, but I see zero signs of any charging happening (e.g. a blinking LED light on the other side).
When using the ports to charge, the charging stops by itself 90% of the time for no apparent reason. I totally regret my purchase.

- Reviewed in the United States on June 30, 2021This product is SOO cool! It's extremely portable so you can slip it into a beach bag or hiking bag. It's on the heavier side due to durability but it doesn't take up a lot of space which i love. The best is that it can charge 2 phones at once and it's fast. One of the phones charged a few % in just a couple minutes. We were stunned. And the best is that you can lie out in the sun on the beach and have it laying next to you charging if you need it. My boyfriend's phone is SO OLD and his battery lasts a few hours at a time when in use so the portable charger has been extremely helpful.
