At a Glance
This comparison targets buyers deciding between a portable, mid-capacity unit and a high-output whole-home backup system. The Delta Pro Ultra X delivers 12,000W of running power and 6,144 Wh of capacity, dwarfing the SOLIX C1000's 1,800W output and 1,056 Wh battery. That gap shows up in device compatibility: the Delta Pro Ultra X powered all 53 tested devices, while the C1000 handled 38 of 53.
Solar input tells a similar story, with the Ultra X accepting up to 10,000W compared to 600W on the C1000. Where the Anker unit fights back is portability and UPS functionality. At 28.4 lbs, it is easy to move between rooms or pack into a vehicle, and its 20 ms UPS switchover keeps sensitive electronics running during brief outages.
The Ultra X weighs 187.4 lbs, making it a stationary install for most owners.
