If briefly - nothing.
EcoFlow River 2 Pro (європейська 200V версія) та EcoFlow River 2 (USA 110V версія) з'єднані Type-C
I have the EcoFlow River 2 Pro (European 200V version) and EcoFlow River 2 (USA 110V version). There was only one outlet near me, and I was charging the EcoFlow River 2 Pro. Then I remembered that the EcoFlow can be charged via Type-C (100W). So I became curious about what would happen if I connected the two EcoFlows using Type-C. Would one charge the other or vice versa? The answer is - no. Most likely, the protection will activate, and Type-C will turn off completely.
On the EcoFlow River 2 Pro, the 'USB-C' indicator sometimes blinks, while on the EcoFlow River 2 - nothing.
