What is the difference between the Explorer 1500 v2 and 1500 Ultra?

The capacity is identical, so ignore that. The decision is about where the station lives.

The shared number

Both listings state 1,536Wh of LiFePO4 capacity. Whatever you were going to run, both run it for the same length of time. This is not a size comparison.

Explorer 1500 v2: more output, faster

The 1500 v2 listing states 2,000W of AC output with a 4,000W surge, seven ports including three AC outlets and dual fast-charge USB-C, and a full recharge in 64 minutes. Jackery describes it as the smallest and lightest 1.5kWh LiFePO4 station at 31.97 lb, rated for over 6,000 cycles.

That is the better machine on paper for indoor and campsite use. More watts, faster refill, lighter to carry.

Explorer 1500 Ultra: built to be abused

The Ultra listing states 1,800W rated output with a 3,600W surge held for five seconds and a 2,000W peak for up to 15 minutes, so it gives up a little continuous power against the v2.

What it gains is the enclosure. Jackery rates it IP65 for dust and water, level 9 seismic shockproof, and drop-resistant from one metre, with a titanium-alloy cooling structure and a bottom-drainage design. Its cells are rated at 4,000 cycles to 70% capacity or better, and it weighs about 38.6 lb.

Which to buy

Pick the 1500 v2 if the station lives inside the camper, the van or the house and comes out to a table. You get more output, a faster charge and nearly seven pounds less to lift.

Pick the 1500 Ultra if it rides in an open truck bed, goes on a boat, sits on a job site, or gets used in weather. An IP65 body is not a marketing flourish on a product that costs this much to replace, and the drop rating matters if it is being handled by more than one person.

If neither fits

If the 1,800W to 2,000W ceiling is the thing you are unsure about, look one size up. The Explorer 2000 v2 listing states 2,042Wh with 2,200W and a 4,400W surge, at about 39.5 lb, which is barely heavier than the Ultra and gives real headroom for a microwave or a heat gun.
