Frequently Asked Questions
How long does a SimplyGo battery last per charge?
Roughly 2–4 hours depending on flow setting — pulse flow extends runtime, continuous flow shortens it. Extended-capacity packs for SimplyGo Mini add hours of unplugged use.
How often should I replace my Philips concentrator battery?
Every 1.5–3 years of regular use, or when runtime per charge drops noticeably. Watch for shorter runtime and faster self-discharge as aging signs.
Are SimplyGo batteries allowed on planes?
Yes — SimplyGo is FAA-approved for in-flight use, and spare lithium-ion batteries travel in carry-on baggage. Always confirm your airline's current policy before departure.
