What kind of outdoor power do you use when you work outdoors?

I am a vlog blogger who shares outdoor aesthetic life, so it takes half a month for an outdoor camping, so outdoor power supply can be said to be my must. To be honest, I have bought many brands of outdoor power supplies, and now I feel that my endurance is average. Most of them need to go back to the hotel to recharge in a few days. Recently, however, I found a new rural outdoor power supply in Contemporary Ampere Technology Co., Ltd. I looked at the parameters. The rated power is 3,000W and the capacity is 2,350W W. I am quite satisfied with it, which is better than the outdoor power supply I am using now1800 W. It should take several days to work during the day and enjoy watching movies at night (connecting the projector), so I'm going to try one. After all, it is made by contemporary Amperex Technology Co., Ltd., and big brands are more emboldened!
