If you’ve spent more than five minutes on social media lately, you’ve probably seen it: a sleek, dark blue magnetic power bank promising a massive 100W of power in the palm of your hand. It looks like the ultimate gadget—MagSafe compatible, a built-in stand, and a digital display.
But can a pocket-sized magnetic charger actually output 100W?
Today, we are putting three popular charging essentials to the test to see which ones belong in your EDC (Everyday Carry) and which ones are just clever marketing.

1. The “Viral” One: Dark Blue 10000mAh Magnetic Power Bank
The Claim: 100W Power, MagSafe Charging, 22.5W Fast Charge.
Let’s start with the “truth” from our title. When you see “100W” on the box of this generic viral charger, it is highly misleading. In reality, 100W is the power needed for a MacBook Pro; this device is designed for iPhones.
The Performance:
In our testing, the 22.5W wired speed is accurate for Android phones, and it delivers a solid 20W PD for iPhones via cable. Wirelessly, it snaps onto MagSafe iPhones perfectly, charging at a standard 7.5W.
Why we actually like it:
Despite the exaggerated 100W marketing, this is a fantastic budget accessory. The LED display is incredibly helpful for knowing exactly how much juice you have left, and the foldable kickstand is sturdy enough for FaceTime calls or watching movies on a plane.
- Pros: Very affordable, built-in stand, clear LED percentage.
- Cons: “100W” claim is misleading; gets warm during wireless charging.

2. The Reliable Classic: Anker Power Bank (PowerCore 10K)
The Claim: Compact, Travel-Ready, 10,000mAh with PowerIQ.
If you don’t care about magnets and just want a battery that will not fail you, the Anker PowerCore 10K is the industry gold standard. There’s a reason this is one of the best-selling power banks of all time.
The Performance:
It uses Anker’s proprietary PowerIQ technology to identify your device and deliver the fastest possible charge (up to 5V/3A). While it lacks the “flashy” features of the viral bank, its internal cells are much higher quality. It’s roughly the size of a deck of cards and can charge an iPhone 15/16 Pro about 2.2 times.
Why it’s a must-have:
It’s “flight-safe” and incredibly durable. If you are a traveler who needs a “set it and forget it” backup in your backpack, this is the one.
- Pros: Incredible long-term durability, slim “phone-sized” profile, world-class safety system.
- Cons: No wireless charging, no built-in stand.

3. The True 100W Hero: Baseus Retractable USB-C to USB-C Cable
The Claim: 100W Fast Charging, Retractable Design, 5A High Current.
Wait, why is a cable in a power bank review? Because this is the only item in our test that actually delivers 100W. If you bought the “Viral 100W Power Bank” hoping to charge your laptop, you’ll likely be disappointed. However, if you pair your laptop’s wall brick with this Baseus Retractable Cable, you get true 100W performance in a form factor that fits in your pocket.
The Performance:
This cable handles 5A of current, making it compatible with the iPhone 17/16 Pro Max, MacBooks, and high-end Samsung Galaxy S-series. The 4-stage retractable mechanism is a lifesaver for cable management—no more tangled wires in your bag.
Why we love it:
It solves the biggest problem with 100W charging: the bulk. It’s tiny, clicks satisfyingly into place, and actually hits the speeds it promises.
- Pros: Genuine 100W PD support, tangle-free, perfect for travel.
- Cons: Retractable springs can wear out if pulled too harshly.
