100W USB C PD port, LiFePO4 batteries, WiFi/Bluetooth-support, four AC ports, fast charging, and the 1000W X-boost were some features that made me say yes when EcoFlow asked if I would like to review it.
I have a lot of good things to say about it, and by the end of this review I hope you feel you know the pros and cons of this product.
I''m going to start like I usually do by going over the features, before I list my opinions.
Table of Contents show Is The River 2 Max The Ultimate Mid-Size Power Station? Features Battery Capacity Inverter Ports Display Charging WiFi/Bluetooth UPS Size & Weight In The Box My Review What I Like What I Dislike Conclusion
The River 2 Max is rated at 512Wh (watt-hours).
To give you a rough estimate: A 512Wh battery will power a 50W device for almost 9 hours with a 85% inverter efficiency (512Wh/50W*0.85=8.7).
The battery chemistry used is LiFePO4 (LFP). These types of batteries are rated for up to 3000 cycles before reaching 80% capacity.
Usually, they''re not as powerful as a household outlet though in terms of how many watts it can output continuously.
The pure sine wave inverter used in the River 2 Max is rated for up to 500W output, but with EcoFlow''s X-boost features it can output up to 1000W with certain devices.
There are four AC outlets (two 3-prong and two 2-prong).
One regulated 12V cigarette port, and two 5.5mm DC outputs.
Three USB A ports rated at up to 12W each, and one USB C PD port rated at 100W input/output.
The display on the front tells the battery percentage, input/output watts, time to empty/full, active ports, and different warnings.
With the included AC wall charger, the River 2 Max can be fully recharged in 1 hour. It takes a little over 5 hours with the included car charger.
Connect it to an existing WiFi-network, and you can be in full control of it even if you''re on the other side of the world.
In the app you can change the charging speeds, turn on/off X-boost, change unit/screen/ac timeouts, and set the discharge level.
Of course, you can also monitor the input/output watts, turn on/off ports, and update the firmware.
UPS stands for Uninterrupted Power Supply. It''s a way to make sure that your devices stay on even during a power outage.
If the power goes out, the power station will quickly switch over to using battery power instead.
