GTOCE 40,000 mAh Portable Charger with 22.5 W Fast Charging and Digital Display

When you’re out for the day and your phone battery is running low, this GTOCE power bank gives you a high-capacity backup with charging cables built in. It’s designed to make charging more convenient without the need to pack separate cables for each connection type.

With a 40,000 mAh capacity and 22.5 W fast charging, it combines substantial battery storage with a faster-charging option for compatible devices. The digital display shows the remaining charge as a percentage, so you can see when it’s time to recharge the power bank.

Built-in Micro USB, USB-C and iPhone cables cover a range of phone connections. USB-A and USB-C output ports add more ways to connect devices, making it practical to share power when you’re out with family or friends.

The essentials

The main advantage is having charging connections and a large-capacity battery together in one portable charger. Instead of carrying a separate cable for every phone, you can use the built-in cables for compatible Micro USB, USB-C and iPhone devices. That makes the power bank a convenient choice for commutes, days away from an outlet or keeping a shared charging option close at hand.

Its 22.5 W fast-charging feature supports quicker charging for compatible devices, while the LED digital display provides a clear percentage reading of the remaining power. The 40,000 mAh capacity gives you a substantial reserve for topping up devices while you’re away from home. For shoppers choosing between a basic battery pack and a model that also reduces the need to carry cables, the built-in connections are a practical difference.

Tips for day-to-day use

Keep the power bank with your everyday essentials when you expect to use your phone throughout the day or need a charging option for more than one person. The built-in cables are useful when you want to leave loose charging leads at home, and the additional USB-A and USB-C outputs give you other connection options for compatible devices.

Check the digital display before heading out to see the remaining charge at a glance. When you’re sharing the power bank, connect devices using the available built-in cables and output ports, the design supports charging up to six devices at the same time. The number of devices you can connect makes it useful for a group outing as well as for carrying several devices of your own.

How to use it

Choose the built-in cable or output port that matches the device you want to charge, then connect the device to the power bank. The built-in cable options include Micro USB, USB-C and an iPhone connector. USB-A and USB-C output ports provide additional connection choices, so you can select the one that suits your device.

Use the LED display to check the remaining battery percentage during the day. When the power bank needs recharging, connect it using its USB-A recharging connection. For faster charging, the connected device must support the power bank’s 22.5 W fast-charging feature.

Before you decide

Which device connections are supported? The built-in cables include Micro USB, USB-C and an iPhone connector. The power bank also has USB-A and USB-C output ports for compatible devices.
