Fix "This accessory uses too much power" Error

When you're plugging in an accessory—maybe a USB-C device, power bank, or even a camera adapter—you might encounter a frustrating notification on your screen: "This accessory uses too much power." If you own an iPhone 15, iPhone 16, etc. or an iPad, this warning might stop your workflow cold.

But don't worry—we’ve got you covered. In this blog, we’ll break down the error quickly and safely. We'll also show you how Veger power banks can help avoid these common issues.

What Does "This Accessory Uses Too Much Power" Mean?

The error "This accessory uses too much power" is a built-in protection feature from Apple devices. It typically appears when the accessory you’re trying to use requires more electrical current than your iPhone or iPad is designed to supply.

Whether it’s a flash drive, external microphone, or third-party dongle, your device may block it to protect itself from potential damage.

In particular, this warning is increasingly common with USB-C equipped devices like the iPhone 16, iPhone 15, and newer iPads. The error may read slightly differently, such as:

• iPad says this accessory uses too much power
• This accessory uses too much power iPad
• Cannot use accessory this accessory uses too much power

It all means the same thing: your device cannot deliver enough power to support the connected accessory.

Why Does It Say "This Accessory Uses Too Much Power"?

Here are the main reasons you’re seeing this message:

1. Incompatible or faulty accessories

Some cheap or counterfeit accessories don’t comply with Apple’s power standards, which leads to this error. Even some non-certified USB hubs can trigger this message.

2. Power-hungry peripherals

Devices like external SSDs, audio interfaces, or cameras draw more power than your phone or tablet can safely provide, especially without external power.

3. Software bugs or iOS updates

After updating to the latest iOS version, particularly on iPhone 16/15, some users report power-related glitches that block accessories.

4. Damaged or dirty connectors

Debris in the Lightning or USB-C port can obstruct the power flow, causing your device to misread the accessory’s power draw.

How to Fix "This Accessory Uses Too Much Power"

Don’t toss out your accessory just yet. Try these 6 methods to eliminate the error and restore functionality:

1. Use a Powered USB Hub

Plug your accessory into a powered USB hub. This provides the external power your iPhone or iPad can’t supply. It’s a perfect fix for large-capacity external drives or card readers.

2. Update Your Device

Make sure your iPhone or iPad is updated to the latest iOS version. Apple may patch bugs causing the error in newer firmware.

3. Restart your device

Sometimes, a simple reboot can resolve temporary software conflicts causing this issue.

4. Clean the charging port

Use a dry, soft brush or a can of compressed air to clear dust and lint from your USB-C or Lightning port.

5. Try a different accessory

Swap out the device. If the error disappears, the issue likely lies with the original accessory.

6. Switch to a certified power source

Using an MFi (Made for iPhone) certified accessory reduces the chance of triggering power-related errors.
