ERRBBIC Solar Charger Power Bank 49800mAh, 22.5W Portable Charger, 15W Wireless Charging, Solar Panel Charger, Built-in Four Cable, with USB C for Cell Phones, with Dual Flashlight for Camping

charger
The ERRBBIC 20,000 mAh solar charger has been very useful, especially for outdoor use. The capacity is enough for several full phone charges, and the 15 W fast charging feature actually makes a noticeable difference. I also like the wireless charging option, which is convenient when I don’t have a cable handy.The dual flashlight is bright and helpful for emergencies or nighttime activities. The overall design feels durable and well-suited for outdoor environments. The solar panel works as a backup power source, although it’s not the fastest way to charge—but it’s great when no outlets are available.Overall, this is a reliable, complete, and convenient power bank for camping, travel, and everyday use.

Powerful and Reliable Solar Charger for Long Trips
The Solar Charger Power Bank 49800mAh is very powerful and works great for long trips. It’s not small, but the big capacity and 22.5W fast charging are really useful. The 15W wireless charging is also a nice bonus.

Excellent Value
Solar panel power is determined in a laboratory setting that is almost impossible to replicate in the real world, so how is one able to evaluate a 100-watt solar panel where none will reach 100 watts in nature? One way is to compare it to a known quality product. This solar panel is a clone of a Jackery Solar Saga 100 and lucky for me I just happen to have one of those too.To understand this panel you have to understand the Jackery and why so many people love it despite its bulky size and higher price tag. The Jackery is a bifold panel on a fairly rigid substrate. It has two wide kickstands making it super simple to deploy and put away. Supporting materials are thick and durable. One of the main failing points of cheap panels is their backing material which doesn’t protect connecting wires and causes short circuits. The Jackery also has magnetic closures keeping its panels secure when not in use. It is a quality design, but you are paying a bit of a Jackery tax for the privilege of using it.This panel is almost identical in size and weight to the Jackery. It takes all of its design cues from the Jackery from its bifold design to its kickstands. The Jackery product comes with a standard plug that works with many Solar Generators, including many Jackerys, Bluettis, and Goal Zeros. It also has an adapter so it can be used with some of the larger Jackery solar generators. This unit comes with 10 different barrel plug adapters as well as an Anderson connector. Both units have a USB A and USB C ports to charge small devices directly, like your phone. The quality of the construction material seems similar, but Jackery’s cloth material may be a tiny bit stiffer.The big question was how well this unit compared with the “gold standard” Jackery. I set up both panels as similarly as I could at around 10 AM in the morning and with an air temperature of around 77F. I then charged either a Jackery 500 which was at 90% capacity or a Bluetti EB3A which was at around 75% capacity. In general, the Jackery 500 seems to limit input wattage to less than 70 watts whereas the Bluetti can accept higher wattages. There was quite a bit of cloud cover so I did the experiment multiple times and at different solar strengths.This solar panel consistently delivered a few more watts than the Jackery Solar Saga 100 Series 3. The end result was that this solar panel was very slightly more efficient than the Jackery during multiple tests.The bottom line is that this product is very similar in design and construction to a Jackery and its power output is very slightly better than a Jackery. I can’t say that it will be as durable but at first glance, it does seem to be well constructed. For me, this is a good value and a buy.
