  "question": "Which breast pumps have a battery that lasts a long time between charges?",
  "answer": "Medela Sonata: The store listing says the pump weighs less than 2.5 lb, has a built-in handle and a rechargeable battery giving 1.5 hours of pumping; the sources disagree on battery life, with the maker saying up to one hour and a review reporting 1.5 to 2 hours. Medela says the battery lasts up to one hour, enough for 3-4 daily sessions before recharging; the sources disagree on battery life, with the store listing 1.5 hours and a review reporting up to two hours.\n\nMedela Swing Maxi: The video shows the hands-free kit has three collection-cup parts, a lanyard, built-in rechargeable battery and USB charging, plus two breast-shield sizes.",
