“I verified the CPAP power brick and humidifier requirements before choosing an adapter for Lithuania.”
— overnight-power planning for Vilnius
Will my CPAP power brick work in Lithuania?
Old-town stays can place outlets away from the desk or bedside table, making a clean cable route and correctly fitted plug more practical than adding an unnecessary converter box. The CPAP power brick is the first item to verify. Lithuania is listed at 220 V / 50 Hz. Many modern CPAP power supplies are wide-input, but you should confirm the exact INPUT line on your brick and any separate humidifier or heated-tube requirements before travel.
If the power brick includes 220 V, the next question is physical plug fit. Lithuania uses C · F; a plug adapter changes the connection shape only and should never be treated as a voltage converter. Between Vilnius and Kaunas, a device that already accepts the local supply only needs a consistent Type C/F plug solution from one stay to the next.

Lithuania power: C · F · 220 V · 50 Hz

Round-pin sockets answer the physical connection question, but not whether equipment bought for a different voltage system is safe to use. CPAP use is different from charging a phone because the load runs for hours while you sleep. In Vilnius, choose a stable bedside outlet, avoid loose adapter stacks, and keep enough cable length to place the machine safely. If a humidifier increases power draw, include that normal overnight configuration in your planning.

EPICKA Universal Travel Adapter — plug-shape option for a verified CPAP supply in Lithuania
In Lithuania, use a passive adapter only after the CPAP power brick is confirmed for 220 V; choose a secure C · F connection and follow the device manufacturer’s guidance.

A compact Baltic itinerary favors power accessories that have a clear purpose instead of duplicate adapters carried for problems that do not exist. Backup power needs to be model-specific. A generic USB power bank is not automatically a CPAP battery. For a trip between Vilnius and , use only batteries, DC cables or inverters that the manufacturer supports for the exact CPAP, and check expected runtime with the humidifier settings you plan to use.
Should I use a voltage converter with a CPAP in Lithuania?
For a longer apartment stay, a destination-compatible cable can be cleaner than leaving a bulky travel adapter permanently attached to the charger. Do not improvise with a small travel voltage converter for medical equipment. If the CPAP power supply does not clearly accept 220 V, contact the manufacturer or equipment provider for an approved solution. The goal is a predictable overnight setup, not simply making the plug enter the socket.
Airline and battery planning for a CPAP trip to Lithuania
Testing the complete setup before Lithuania is especially useful for proprietary chargers that are harder to replace quickly once the trip begins. Air travel adds a separate checklist: keep essential CPAP equipment and permitted batteries where airline rules require, protect terminals on spare batteries, and verify current carrier requirements before departure. Electrical standards in Lithuania are only one part of keeping therapy available throughout the trip.
