Learn how to charge your phone with a portable fan that doubles as a power bank. Step-by-step guide for using the ToughTested fan battery on the go.

Quick answer

Yes, you can charge your phone using a rechargeable fan with a built-in power bank. Simply connect your phone via USB-C cable and press the power button to start charging.

Why use a fan as a power bank?

A rechargeable fan with a built-in battery is more than just a cooling device. It can serve as a backup power source for your phone when you're outdoors, camping, or during a power outage. The ToughTested Portable Air Cooler & Power Bank, for example, combines a 3-speed fan with a 5000mAh battery, letting you stay cool and keep your devices charged without carrying extra gear.

The main trade-off is battery capacity. A 5000mAh fan power bank can fully charge most phones once or give a partial boost to a larger device. It's not a replacement for a high-capacity power bank on multi-day trips, but it's a smart dual-purpose tool for short outings.

How to use your rechargeable fan as a power bank

Step 1: Fully charge the fan: Plug the fan into a USB-C charger using the included cable. Wait until the battery indicator shows a full charge before relying on it as a power source. A partially charged fan may not provide enough power for your phone. A common mistake is assuming the fan is ready to charge your phone right out of the box. Always charge it fully first.
Step 2: Connect your phone: Use the USB-C cable that came with the fan (or your phone's cable) to connect your phone to the fan's USB-C output port. The fan's power bank function activates automatically when a device is connected. If your phone doesn't start charging, try pressing the fan's power button once to wake the battery output.
Step 3: Monitor charging and fan use: You can use the fan on low, medium, or high speed while it charges your phone. Keep in mind that running the fan drains the battery faster, so if your priority is charging, turn the fan off or use the lowest speed setting. Check the battery level periodically. The fan will stop charging your phone when its battery is depleted, so conserve power if you need both cooling and a phone charge.
Step 4: Use the clip or lanyard for convenience: Attach the fan to your belt, backpack strap, or clothing using the included waist clip. You can also wear it around your neck with the lanyard. This keeps the fan and your phone close together while you move around. Avoid dangling the phone by its cable. Use the clip to secure the fan and keep the connection stable.
