The Belkin UltraCharge Power Bank 22K with Retractable Cable and Smart Display is a portable battery pack you can carry with you to charge your phone, tablet, laptop, and other devices when you're away from a wall outlet.

You can choose from three stylish colors: Black, Sand (Europe only), and Deep Blue (Europe only).

Yes! It comes with a 2-year limited warranty. Plus, you also get a $2,500 Connected Equipment Warranty, which helps protect your devices if something goes wrong while they're being charged.

The power banks themselves are exactly the same. The only difference is the packaging. The Amazon version comes in a plain brown box (frustration-free packaging), while the retail version comes in the full colorful retail box. Same product, same performance, same warranty.

You'll get the power bank itself, along with a quick-start guide and warranty information. Since the charging cable is built into the power bank, no extra cable is included in the box.

Yes, it comes pre-charged and ready to use right away. We do recommend giving it a full charge before your first long trip to get the most out of it.

It's a compact 131 x 54 x 52.8 mm, small enough to fit in a jacket pocket, side pocket of a backpack, or purse.

It uses 4 premium Samsung 58E 21700 lithium-ion battery cells, the same kind of high-quality cells used in top-tier power banks and electric vehicles.

It has a huge 22,000 mAh capacity, enough to charge most smartphones several times over.

You get three ways to charge: a built-in retractable USB-C cable, a separate USB-C port, and a USB-A port. That means you can charge up to 3 devices at the same time.

The retractable USB-C cable is 70 cm (about 27.5 inches) long when fully extended, plenty of length to keep your phone in your hand while the power bank sits in your bag.

Absolutely. The cable is tested for over 10,000 pull-out and swing cycles, and it's built with a flame-resistant (VW-1 rated) material. It's designed to last for years of daily use.

Yes! Pull the cable out all the way to 70 cm and it will automatically lock in place, staying taut while you charge. When you're done, just give it a gentle tug and it retracts smoothly back into the body.

The smart digital display has three views you can cycle through by pressing the button: (1) Battery percentage: shows how much power is left; (2) Wattage output: shows how fast each port is charging in real time; (3) Temperature/safety status: shows the internal temperature and any safety alerts.

Just short-press the button on the power bank once to wake the screen, and press again to cycle through the three views. Hold the button for 2 seconds to turn the screen off.

Yes, to save battery, the display automatically turns off after 30 seconds of no activity. It will light up again when you press the button or plug in a device.

Yes, we use eco-friendly materials at least 75% of the plastic housing is made from recycled materials, and it carries GRS environmental certification.

Yes! You can charge up to 3 devices at once using the retractable cable, the extra USB-C port, and the USB-A port together.

Yes! It's compatible with virtually any device that charges over USB-C or USB-A, including Google Pixel phones, wireless earbuds, cameras, e-readers, Bluetooth speakers, and more.

Nope, no app needed. There is no companion app or PC software required. Everything you need to know is shown right on the built-in display, just plug in and go.

Really fast! It delivers up to 65W from a single port and up to 120W total when using two ports together, that's laptop-class fast charging. Your phone charges in a snap, and your laptop stays powered while you work.

With 22,000 mAh of power, it can charge most modern smartphones several times over on a single charge of the power bank. You'll get plenty of top-ups for even the longest travel days.

Plug a USB-C wall charger (up to 65W) into either the retractable cable or the USB-C port. It fully recharges from empty to 100% in about 2 hours with a 65W charger.

Yes, this is called pass-through charging. Your device gets charged first (at up to 15W), and once your device is topped up, the power bank refills its own battery. This helps protect the battery for a longer life.

We limit pass-through to 15W on purpose. This gentle charging is easier on the internal battery, helping it last much longer over the years. Think of it as spa treatment for your battery.

Yes! At approximately 81 Wh (well under the 100 Wh airline limit), it's approved for carry-on luggage on most airlines. Just remember: it must go in your carry-on bag, never in checked luggage. Always double-check with your specific airline for their latest rules.

Yes, it's completely safe. The power bank has dual-chip smart protection that monitors temperature and power flow every 20 milliseconds. It automatically prevents overcharging, overheating, and other safety issues.

A few reasons this can happen: (1) You're using multiple ports at the same time and the power is being shared; (2) The environment is warm, and the power bank has reduced output to stay safe; (3) Your device or cable doesn't support the fastest charging speed. Try using just one port with a high-quality USB-C cable for the fastest results.

First, make sure it has a charge. Plug it into a wall charger for 15-30 minutes and try again. If the display still doesn't light up, contact Belkin Support with your proof of purchase and we'll be happy to help you under warranty.

Yes! Thanks to pass-through charging, you can plug in your devices even while the power bank itself is charging. Your devices get powered first, then the power bank tops itself up.

Store it at room temperature in a dry place. If you won't be using it for a long time, we recommend keeping it around 50% charged and topping it up every few months to keep the battery healthy.

Like all lithium batteries, capacity does slightly decrease over years of use, which is normal. However, if it stops holding a charge much sooner than expected and you're within the 2-year warranty, contact Belkin Support with your proof of purchase and we'll take care of you.

Head to the Belkin Support website or reach out to our customer service team. Have your proof of purchase handy, and we'll be more than happy to help whether it's a question, troubleshooting, or a warranty claim.
