When to Choose ESR CryoBoost 3-in-1 25W Stand
Users who prioritize sustained fast-charge speeds and want active thermal management in a 3-in-1 dock
The ESR CryoBoost stands out with its active cooling fan that prevents heat throttling during 25W charging. If you charge your phone while using it heavily, the CryoBoost maintains consistent speeds — but the fan noise may bother light sleepers.
Strengths
- 25W Qi2.2 with CryoBoost fan actively cools to maintain top speed
- Built-in fan reduces phone temperature by up to 4°C during charging
- Charges iPhone, Apple Watch, and AirPods simultaneously
- Strong magnetic alignment holds phone securely in landscape or portrait
Limitations
- Fan noise is audible at close range — not ideal for nightstands
- Bulkier base than fanless competitors
- Limited to Apple Watch — no Samsung watch charging

- Premium vegan leather finish and magnetic closure
- MFi-certified Apple Watch charging built in
- Smallest travel footprint of any multi-device charger tested
Limitations
- 2-in-1 only — no dedicated AirPods charging spot
- 15W Qi2 charging speed trails faster alternatives
- $100 is expensive for a 2-device charger
