Spectra S1 vs Spectra Dual Compact

Spectra Dual Compact8.0Around £200Amazon

The short answer

Both are closed-system double pumps with 12 suction levels and a built-in battery, but they suit different routines. The S1 is the bedside-style workhorse: up to 250mmHg, about three hours per charge, a night light and a timer. At around 1.3kg, though, it's portable around the house rather than in a bag. The Dual Compact weighs 635g, charges by USB-C and has two motors, so you can set each side separately, with Spectra quoting up to 300mmHg. Its battery lasts about two hours.

Two things tip the balance towards the S1 for most people. It's around £40 cheaper, and it has a strong record of owner feedback, while there's little independent testing of the Dual Compact so far. Check shield sizes either way: the S1 comes with 24mm shields and the Dual Compact with 28mm, which will be too big for many people.

My call: the S1 for most frequent pumpers, especially if you mostly pump at home. Pick the Dual Compact if your two sides respond differently or you need to pump on the move, and budget for smaller shields.
