The MEMO DL21 uses a thermoelectric contact plate and a fan to remove heat from a compatible smartphone. Its clip-on housing and threaded mounting point suit mobile-gaming and live-streaming accessory assortments.
- Active phone cooling: A thermoelectric plate transfers heat from the phone while the fan exhausts it through the housing. Cooling results depend on the phone, power supply, contact and surrounding temperature.
- Attachment and mounting: Spring clips secure the cooler to a compatible phone. A threaded mounting point supports a suitable stand; a stand and phone are not included. Check fit and camera clearance before use.
- Cooling controls: Dual fans, digital temperature display and three operating levels. Cooling performance depends on contact, supply and ambient conditions.
- USB-C power: Rated input 5 V / 2 A. External power is required; this cooler does not charge the phone.
- Wholesale and retail supply: Choose a listed color for one cooler set. Wholesale starts at 100 sets, with listed colors mixable within the minimum.
