ECO PLAY 1800W Portable Power Station EP1800, 1536Wh LiFePO4 Battery Backup, Expandable to 4kWh, 1200W Solar Input, UPS, APP, for Camping/Outdoor

I have a few power stations but needed something bigger for home and holidays. I have been testing it now for a couple of weeks and it has worked exactly as it should. There IS a downloadable app called BrightEMS. The app identified the power station first time and it has communicated well so far. The attached pic shows the app running with the power station charging from the mains at 1200 watts and at the same time charging another power station via USB-c . I have also charged it on the road with an alternator charger (Bluetti Charger 1) at 560 watts which will be great for touring. Finally, I did have some correspondence with the seller and found them to be responsive and helpful. Very happy with this purchase.

I got a great limited time deal on this Power Station - it arrived well packaged and I have tested to it's advertised limits succefully. It is a well put together and attractive unit with a large battery and inverter capacity but in a surprisingly compact chassis - I also had great communication from the supplier who quickly replied to product specification questions. I Highly recommend this Power Station and the seller..

I bought this and it works flawlessly one reason I bought it is because later I could add on extra power if I needed it. But I find now that the extra batteries are not available

Further update: Replacement device still has issue, a switch and router are connected to this device for UPS purposes. It randomly kills both input and output AC, killing my switch and router, and voids the purpose of the equipment. The team are unable to tell me how to troubleshoot, the logs are blank and the unit requires a power cycle swith the On/off to resume delivery of AC power to sockets. Do not buy this as a UPS. It is not fit for purpose. Updating my previous review. The team have been amazing with support, helping me configure the device and even shipping me warranty replacements when things were not quite right, the communication from the team in China is amazing. The 1800w device now gives 6 hours backup to my critical lab equipment with flawless failover. Brilliant!
