512Wh Portable Power Station with 100W Solar Panel, LiFePO4 500W Solar Generator UPS Backup Battery Power Supply with 10 Outlets(3 AC Outlets) for Outdoors CPAP Camping RV Home Power Outage

I have used this to charge an iPad and an iPhone at the same time, both using usb-c ports, neither require the full capacity of the available output. I have used the regular usb port, and the AC output, and was surprised how much power a basic 8 inch house fan uses. This power bank is good quality and a good value with all of the available ports. The casing is sturdy, and it has better batteries that can be charged more times the others near this price. The item is fairly heavy like all the others. This pulls a lot of power when recharging, so it’s best to plug it directly into a wall outlet, and allow several hours to charge if it has a 25% remaining charge in it. The instructions say it will use some charge each month, even if it hasn’t been used, so it needs checked periodically. I think the quality is good and it’s easy to use. The company is Chinese owned.

This little (well not this model -- it's about 35 pounds) guy is amazing. I run a small server farm inside my house. One of the largest servers can consume around 750-900 watts of power when using the Nvidia A100 card while both CPUs are pegged to the max (112 cores total).If I were to use a standard UPS with a lead acid battery, I'd have about 5-7 minutes of power after the mains go down. LifePO4 is the future for UPS because these batteries don't care if you drain them completely -- while a lead acid battery ideally would not drop below 80% of its rated power.After receiving this unit, I tested it on a number of different appliances and a few servers. The AC outlet delivers true sine wave which you can hear when running a motor. It's clean AC power thru and thru. The amazing thing is how long my "supercomputer" can run for on this beast. The server stayed up for around 97 minutes on full load. Most of our power outages are fixed in 4 hours. What I can do is pause the rendering / A100 card and lower the core usage to buy myself another 2 and half hours and I'm golden!CONS: It's hard to give this unit true cons, but one con is that if you use it for a UPS device, there is no way to hook it up to your computer to tell the computer it is on battery power. HOWEVER, there is a cheat for this! You can purchase a Kasa Smart Plug (KP115) and put it into the outlet behind the AC for this unit. The Kasa unit has bluetooth to monitor energy. When the power goes out, Kasa will stop reporting. A simple Python script can be created to monitor the Kasa plug and when it goes out, you know the server is running off battery!Other things to note about this device -- It is made in China. Made in China doesn't mean inferior products -- it just means you need to be careful because build quality is highly variable from that country. For this unit, the build quality is excellent. The unit feels very sturdy and the plastic mold is very high quality.If you are looking for a UPS device that can transfer between outlet and battery in 5ms (the standard for computer power supplies is to maintain power for 25ms after a power outage) then this unit is for you! The UPS will last far far longer than lead acid battery types and the battery itself may very well last longer than you!I highly recommend this product for any home server geek who wants a high quality UPS for multiple servers. If you have a NUC server farm, this can easily power 10+ NUCS for hours at a time.One of my best purchases in quite a while.

Love this unit. Build quality is good, display is great and the UPS function worked flawlessly during hurricane Milton. Charging speed is fast, runs quiet, size and weight make it easy to move around.

It works, just they do not use a standard plug for the solar/DC input. So if your adaptor from this plug to Mc4 goes bad you are going to find a hard time getting a replacement. The other thing is on the front it has the DC output listed at 10 amps but that is only for the car plug and not the 5512 plug which is only 3 amps. Last thing the output meter on mine reads low by about 10 watts on a 100 watt load.I'm going to try and contact the seller and see if I can get the an extra cable as a spare, if so will update.They replied back to me, it is call a M20 connecter. I was able to find two on amazon One with a Mc4 and one with a Anderson. The Mc4 is here https://www.amazon.com/dp/B0CGJ3W8ZS?psc=1&ref=ppx_yo2ov_dt_b_product_details. With only two on amazon with this M20 connector I have to keep my rating the same. But added a star for them getting back to me quickly. I order two extra ones because if this battery pack does last 10 years who know if this connector will be available that long. When your camping things get broke or lost.
