Which covers a bigger room?

The FEPPO claims 1,000+ sq ft. The AE103 lists 1,679 sq ft in its specs but 500 sq ft in its own product text, so treat its real coverage as uncertain. For a large open space, the FEPPO is the safer pick.

Which is better for a bedroom?

The AE103 is quieter at 35.6 dB and its app lets you set a light overnight schedule. The FEPPO's 1/2/4/8 hour timer is simpler but its output is rated for much larger rooms.

Is the AE103 worth it over the FEPPO?

It costs less, $37.98 at Amazon versus $47.99 at eBay as of November 7, 2026, and adds a battery and app control. The FEPPO gives you more oil capacity and included oils.

Which lasts longer between refills?

The FEPPO holds 120 ml versus 109 ml for the AE103, so slightly more oil. The AE103 states 449 hours of scheduled running per fill, which the FEPPO does not publish.

Do I need to buy oil separately?

With the FEPPO, no: five 20 ml oils are included. The AE103 ships without oil, so budget for fragrance on top of its price.

Can I use either without an outlet nearby?

Only the AE103. Its 7,200 mAh battery runs up to 17.8 hours per charge. The FEPPO is corded electric only.
