Honestly, the tempearture control runs between 37 and 42°C, which is pretty tight for a unit this small, but here's the thing—most buyers we deal with find that range actually works better for the targeted EMS contouring than broader bands on teh pricier stationary machines, since you can leave it on longer without worrying about burns or discomfort.

What it basically does is combine the EMS frequency range of 30 to 300Hz with a 1MHz RF output and that red wavelength at 60nm (give or take 10nm), so you're getting muscle stimulation and surfce heating simultaneously without having to switch modes, and the 1200mAh battery drives all that for about 20 minutes or so per charge, which is usually enough for a focused session on one area.


It's not a heavy-duty clinic unit—160g and smaller than your phone, so if you're planning to melt off inches in a single go, you'll be disappointed, but for maintaining tone after weight loss or for that client who wants something portable to use between salon visits, it's actually better than the full-body pads because you can target exactly where it's needed.

The color is white as standard, but we've done custom runs in matte black and even a rose gold for some salon chains, and the materail is ABS and PC with a stainles steel contact plate, so it holds up fine to the alcohol wipes and occasional drop, though I wouldn't recommend submerging it obviously—that's just common sense for any electronic body device in this category.

We usually carry about 200 units in stock for immediate shipment, but if you're ordering more than 50 units, confirm lead time because the custom color or logo imprint adds roughly 10 working days to production, and the MOQ for custom packaging is 100 pieces, though for plain white our company can split boxes down to 20 units if that helps your budget.
Our MOQ for the F1 is 100 units for standard white, but we can negotiate for custom colors if you order 500+ units. Just let us know your Pantone code.
Lead time is about 15-20 days for a standard order of 100-500 units. Custom colors or packaging might add 5-7 days.
Yes, we have CE and FCC certifications for the F1. We can also share the EMS frequency accuracy test and temperature control calibration reports upon request.
Yes, you can set it in 1°C increments from 37 to 42°C. The stainless steel head maintains within ±0.5°C during use, so it's pretty steady.
Each unit is packed in a 19*10*6cm box weighing 230g. We can do blister packs or custom boxes for retail, just specify your needs.
