Can I connect DELTA together?
Answer: Theoretically speaking, you can connect as many DELTAs in serial (but not in parallel) as you want. However, the efficiency of the machines will be seriously compromised (The energy consumption of the inverters grows with the number of the connected machines). As a result, we do not recommend to connect more than 3 DELTAs in serial, and it is necessary to fully charge every DELTA before you connect them together. Moreover, connecting DELTA in serial will not increase the rated output, but will expand the capacity.

How to turn the X-boost function on?
Answer: Click "AC" on the device page of the APP, and you could turn on the "X-Boost" function after entering the page.
*In order to save power, it is recommended to turn off the X-boost function when you don’t need to use it.
*X-boost technology's built-in advanced algorithms lower the required output of the heavy-duty devices. That means a smart 600W inverter can run devices with up to 1200W per draw.
*X-Boost mode is NOT suitable for ALL appliances. Some 600W-1200W appliances with strict voltage requirements may not function (eg. air compressor). Please test to confirm before using the device. X-Boost mode is enabled by default. You can disable it on the APP.

What are the differences between the RIVER Pro and the R600 Pro?
Answer: Here we listed some similarities and differences between the RIVER Pro and the R600 Pro:
RIVER Pro and R600 Pro have a similar capacity: RIVER Pro: 720Wh vs R600 Pro: 768Wh. Both can be recharged via AC wall outlet, 12V car charge and solar panels and has 10 available outlet options, including 3 x AC output, 2 x USB-A, 1 x USB-A fast charge, 1 x USB-C, 1 x Car cigarette output, 2 x DC5521. Both can be recharged from 0% to 80% in 1 hour and fully recharged 1.6 hours.
RIVER Pro has the advantages in wider discharge temperature range and lighter weight. R600 Pro has the advantages in longer lifecycle and capability to connect an additional unit in parallel via X-link.
RIVER Pro and R600 Pro have their own accessories options. For instance, the RIVER Pro and the R600 Pro do not share the same Extra Battery option: The RIVER Pro can connect to a RIVER Pro Extra Battery but the RIVER Pro Extra Battery does not work with the R600 Pro. Meanwhile the R600 Pro can connect to an EF1500 but the EF1500 does not work with the RIVER Pro.
The RIVER Pro is now selling at EcoFlow Official website, Amazon.com and other authorized EcoFlow dealers.
