Which one runs a fridge longer?

The Anker S2000. Anker claims it keeps a fridge powered for 35 hours, and its 6W idle draw and higher efficiency stretch runtime. The S2400 has slightly more capacity but no comparable runtime claim.

Can the S2000 run a space heater?

Most space heaters draw 1500W, right at the S2000's continuous limit. The S2400 handles 2400W continuously, so it is the safer choice for heaters and power tools.

Which battery lasts longer?

The S2000 is rated for up to 10,000 cycles (about 15 years). UDPOWER does not state a cycle life for the S2400, so the S2000 has the clearer longevity claim.

Is the S2400 worth the extra money?

At $699.99 versus the S2000's recent $679.99, the S2400 costs about $20 more. It is worth it only if you need the higher 2400W output; otherwise the S2000 is the better value.

Which is easier to carry?

The S2000 weighs 35.7 lb and measures 8.2 x 11.1 x 12.7 in. The S2400 weighs 40.8 lb and is wider at 15.8 in, so the S2000 is easier to move and store.
