In our previous article, we discussed a few troubleshooting steps you could try to help prevent your wireless charger from overheating. However, if you notice frequent cutoffs in charging and are concerned about your device’s high temperature, we recommend investing in a wireless charger with a cooling fan.
But does strapping a fan to the back of a wireless charger reduce temperature and improve performance? Well, certainly yes. Active cooling continuously pumps heat out of the system rather than relying on surrounding airflow to take heat away from the system.
Getting your hands on a reliable wireless charger, especially one with a cooling fan, is pretty essential. A good manufacturer will take care to include a well-built fan that stays silent and lasts longer. Also, most wireless chargers with a cooling fan come at a higher price than those available on the market, so getting one with the right features can save you money.
We researched the best wireless chargers with cooling fans on the market and came up with the best ones below. However, before buying, we recommend you give a read to the perks and drawbacks and go through what to look for in a wireless charger with active cooling.

Perks and Drawbacks
Actively cooled wireless chargers are a great replacement for your existing overheating charger. However, here are some things you should know before picking a wireless charger with a cooling fan:
The main advantage of a fan in a wireless charger is its ability to push heat out of the system. The thin copper coils present in wireless chargers heat up as current flows through them, similar to how an electrical appliance gets hot with extended use. If the charger is incapable of letting heat out quickly, your device will stop charging to prevent overheating, increasing the charging time. High temperatures can also degrade your device’s battery, especially if you use wireless charging daily.
The lower temperatures of actively cooled wireless chargers enable manufacturers to equip them with faster charging. For example, the OnePlus 8T can charge at a 30W wireless charging speed, even faster than most wired options out there. This makes it easier to adopt wireless technology, as the current 10W charging is too slow for smartphones.
Fans tend to produce quite a lot of noise. Laptop and PC owners here can relate to the annoying sounds of their device fans at high loads. Wireless chargers with fans are in a similar league. Although device manufacturers have made sure to use high-quality fans, the charger could still produce a small noise level that may disturb you.
Considering most users prefer to charge their smartphones overnight, fan noise can be a potential dealbreaker if you decide to use one near your bed. To combat this, most wireless chargers come with a quiet mode that reduces the fan speed for a quiet operation at the cost of the charging rate. As you will be charging your smartphone overnight anyways, the impact seems minimal.
The additional research and material costs associated with adding a fan are the main reason actively cooled wireless chargers price significantly higher. Compared to regular wireless chargers, some cost as much as double, making them quite expensive. However, since most wireless chargers go on sale frequently, it’s just a waiting game till you can bag a sweet discount on one.
How to identify a good wireless charger with a cooling fan
While buying a wireless charger with a cooling fan, we recommend going through our list of essential features to consider. You may also not need some of the features listed and can save a bit of money by opting for a cheaper charger instead.
Any fan control on an actively cooled wireless charger is a necessity. While running fans at full tilt may seem to be a good idea for thermal, the noise is disturbing enough to keep you awake at night or disturb your workflow if placed nearby. Most chargers let you control the fan speed by reducing the charge rate to a more standard 10W. You can configure it via your smartphone and set schedules for work and bedtime where the wireless charger will minimize the fan speed for lower noise.
Any wireless charger in the market today needs some form of certification to guarantee compatibility and safety with a range of devices ranging from smartphones to wireless earbuds. While choosing a wireless charger, ensure that it has a certification, preferably from Qi. Most manufacturers include Qi certification for regular charging speeds of up to 10W.
For specialized charging rates with custom standards like 15W Samsung Fast Charge 2.0 and 30W OnePlus Warp Charge 30, the device you are using will need to support them explicitly to charge at such speeds. Other devices will simply revert to Qi-standard 10W charging.
Most smartphone users employ cases as a means for protection. However, the addition of cases adds a significant thickness to the smartphone’s back, increasing the wireless charging coils’ distance. Many wireless chargers cannot change with even a slim case making it a hindrance to remove the case every time you need to charge. Premium chargers will support a thickness of up to 8mm, supporting even the market’s bulkier cases.
As discussed before, the charging rate of a wireless charger depends on the standard it operates at. Typical Qi-enabled chargers will charge at 10W, although the newer standards allow for 15W charging. But, the maximum charging rate you will be able to squeeze out of a wireless charger solely depends on its specifications. Only a handful of devices like the OnePlus 8T support faster than 15W charging, but the list continues to grow, and we expect it to become the new standard with the new generation of smartphones that will launch this year.
A wireless charger is still a wired device that needs to be plugged in to function. Most wireless chargers come equipped with a USB Type-C port for power delivery and support power bricks capable of supplying the necessary power. Many premium manufacturers like Samsung bundle a power brick and cable with their wireless chargers. OnePlus instead opts for a non-removable solution, which may be tough to repair if the brick fails. An included charger’s benefit is that you need not spend extra on another accessory, especially if you are on a tight budget, so keep that in mind while shopping for a new wireless charger.
While charging speeds might be one aspect to look for while buying a wireless charger, the support for devices like smartwatches and earbuds are also vital if you tend to charge those devices wirelessly. While a wireless charger with a cooling fan is undoubtedly overkill for such low-power devices, charging them simultaneously with a smartphone is a fair use case to invest in one. Some actively cooled dual wireless chargers are already out in the market and you can check them out to see which one is good for you.
