Capacity
DELTA 2 Max: +1,220 Wh (+147.3%).
This comparison targets buyers choosing between a high-capacity home backup station and a lighter, more portable unit. The DELTA 2 Max delivers 2400W of running power and 2048 Wh of battery capacity, giving it the muscle to handle 45 of the 53 devices we tested. The Jump 1500X managed 33 of 53.
Solar charging further separates the two: the DELTA 2 Max accepts up to 1000W of solar input and works with 19 compatible panels, while the Jump 1500X tops out at 200W and pairs with 12. Both use LFP chemistry rated for 3000 cycles, and both support expansion batteries. The tradeoff is size and built-in UPS.
At 36.2 lbs, the Jump 1500X is about 14.5 lbs lighter and includes UPS functionality, a feature the DELTA 2 Max lacks.
