Can the AIMTOM 42000mAh 155Wh Portable SPS-155 run your CPAP or other small medical devices?

For your own setup, check the device’s running wattage first, then match its voltage and plug type before you plan an overnight use case.

SPS-155 battery and outlet ratings determine CPAP compatibility

The SPS-155 has a 155Wh battery and a 100W AC outlet rating, so the answer depends on the CPAP’s continuous draw, not its startup label. We picked it for a full review because those two figures decide the outcome for this use case. The inverter type is not stated, so you should not assume a pure sine wave output for sensitive medical gear. A CPAP is a small air pump with a battery behind it, and that makes wattage and runtime the two numbers that matter most here.

What to Check Before Buying the SPS-155

• Check your CPAP’s running wattage. The SPS-155 supplies 100W on AC, so a device that draws more will not be a fit.
• Check whether your medical device needs a pure sine wave. The inverter type is not stated, so this matters for sensitive electronics.
• Check your expected runtime in watts, not just in hours. A 155Wh pack can empty quickly if your CPAP draws more power than you expect.
• Check for any startup surge or inrush current. Motors and compressors can ask for more power at start than they use while running.
• Check whether your setup needs pass-through charging. The charging modes are AC wall, car port, and solar panels, but stable simultaneous use is not stated.
• Check for a low-battery warning or auto shut-off threshold. That detail is not stated, and it matters if you need overnight warning time.

Where the SPS-155 Sits Among Portable Power Stations

The SPS-155 sits in the small portable power station class, not the 300Wh overnight-backup tier or the 1,000Wh range used for longer appliance runs. If you need a unit for a CPAP, a phone charger, or another low-watt medical device, its 110V AC output and 3.48lb weight make it easy to place in a carry bag. If you need longer sleep-cycle runtime, higher surge headroom, or a confirmed pure sine wave inverter, you should look at larger or more specialized portable power stations instead. Choosing the wrong size here usually means a return and a second purchase.

Choose the SPS-155 if your CPAP or medical device stays under 100W and you want a compact 155Wh station with AC, USB, and 12V outputs. Skip it if your device needs more wattage, longer runtime, or a stated pure sine wave output.
