Belkin Portable Charger Power Bank 10,000mAh Review

Looking for a reliable power bank to keep your devices charged on the go? I’ve spent the past month testing Belkin’s 10,000mAh portable charger, and it’s proven to be quite practical for daily use.
This compact power bank stands out with its built-in Lightning and USB-C cables, eliminating the need to carry separate charging cords. The integrated design keeps everything neat and tidy in your bag.
The 23W output delivers quick charging, and you can power two devices simultaneously. During my testing, it charged my iPhone from 15% to full while using only a quarter of the power bank’s capacity.
The LED indicator lights make it simple to check the remaining charge. Pass-through charging lets you recharge both the power bank and your device at once, which proved useful during overnight trips.
Bottom Line
The Belkin portable charger offers convenient built-in cables and reliable charging performance for your daily needs.
At 10,000mAh, it provides more than enough power for a full day of device use.

Overview: Belkin Portable Charger
This power bank solves a common travel frustration with its clever built-in cables design. You don’t need to pack or hunt for extra charging cords since both Lightning and USB-C cables are integrated right into the unit.
The 10,000mAh capacity provides plenty of power for your devices. A full charge delivers around 31 hours of extra use for an iPhone. The 23W output lets you charge two devices simultaneously using the built-in cables.
The compact black case feels solid and well-made. At just half a pound, it’s light enough to carry daily. The LED battery indicator is bright and easy to read.
Pass-through charging works smoothly – you can charge your phone while also charging the power bank itself. The only minor annoyance is that you need to press the power button before charging an iPhone, while Android devices start charging automatically when plugged in.
Key Features:
- Built-in Lightning and USB-C cables
- 10,000mAh capacity
- Dual device charging
- LED power indicator
- Pass-through charging support
10,000 mAh Capacity
The substantial 10,000 mAh battery capacity provides enough juice to fully charge your iPhone multiple times before needing a recharge. During testing, this power bank delivered about two full charges to an iPhone 15 Pro Max with some power left to spare.
The battery pack maintains a steady charge rate throughout its capacity range. You won’t notice any significant slowdown as the power bank’s charge level decreases.
Recharging the power bank takes approximately 3 hours when using a 20W USB-C power adapter. A handy LED indicator shows the remaining capacity, so you’ll know exactly when it’s time to recharge.
The compact size makes this 10,000 mAh capacity impressive. You get substantial charging power while the device remains portable enough to slip into a bag or large pocket.
Integrated Charging Cables
Having two built-in cables directly attached to the power bank makes charging multiple devices a breeze. The integrated Lightning and USB-C cables stay neatly tucked away when not in use, eliminating the need to carry separate cords.
The cables feel sturdy and well-made. You won’t need to worry about forgetting or losing charging cords during travel. Both cables can be used simultaneously to charge two devices, which is perfect for sharing power with friends or family.
One small drawback is that you need to turn on the power bank before using the Lightning cable with iPhones. The USB-C cable works instantly when plugged in.
The integrated design keeps everything compact and tangle-free in your bag. When you need to recharge the power bank itself, you can use the USB-C cable for pass-through charging while still powering your devices.
23W Dual Device Charging
The dual charging capability really shines when you need to power up multiple devices at once. This power bank delivers up to 23W of total output, letting you charge two devices simultaneously through the built-in cables.
When charging both an iPhone and USB-C device together, the power splits efficiently between the ports. Your iPhone receives up to 12W while your USB-C device gets up to 11W – enough to keep both devices charging at a reasonable speed.
You’ll notice the charging speed slows down a bit compared to using a single cable, which is expected when sharing the power output. The built-in cables make it convenient to charge without carrying extra cords, though you can only charge Apple devices through the Lightning cable.
The power distribution works reliably and predictably. You can easily monitor both devices’ charging progress through their individual battery indicators.
Pass-Through Charging Feature
The pass-through charging capability is a game-changer for keeping devices powered up efficiently. You can plug the Belkin power bank into a wall outlet while simultaneously charging your phone through either the built-in Lightning or USB-C cable.
When using pass-through charging, the power bank delivers up to 18W of power to your device. This means your iPhone or other compatible device charges quickly even as the power bank itself recharges.
This feature saved me desk space and eliminated the need for multiple wall adapters. I found it especially useful while traveling, as I only needed to pack one charger to keep both the power bank and my phone topped up overnight.
The power bank continues to charge your devices normally during pass-through operation, with no noticeable reduction in charging speed or performance.
LED Indicator Light
The LED power indicator shows remaining battery capacity through a simple 4-light system. When you press the power button, you’ll immediately see how much charge is left in the power bank. Each LED represents roughly 25% of the total capacity.
A quick glance lets you check if you need to recharge the unit. The white LEDs are bright and easy to read, even in daylight. They’re positioned conveniently on the front panel next to the power button.
The lights automatically turn off after a few seconds to conserve power. This thoughtful design prevents unnecessary battery drain while still providing clear status updates when needed.

Pros and Cons
