At a Glance
This comparison targets buyers weighing a high-capacity whole-home backup unit against a lighter, more portable option. The DELTA Pro 3 delivers 4000W of running power and 4096 Wh of capacity, powering 48 out of 53 devices tested, while the Jump 1500X handles 33 of the same 53.
That gap matters for anyone running large appliances or multiple circuits simultaneously. Solar input also diverges sharply: the DELTA Pro 3 accepts up to 2600W from up to 20 compatible panels, compared to 200W and 12 panels for the VTOMAN.
Both use LFP chemistry and support expansion batteries, but the tradeoff is real. The DELTA Pro 3 weighs 113.5 lbs, more than three times the Jump 1500X's 36.2 lbs, and it lacks the built-in UPS transfer the VTOMAN includes.
