You plug a cable into your phone and the lightning bolt icon appears. "Good, it's charging." Until now, that was enough. But the truth is, gadget lovers want more. "Is this really fast-charging?" "How many minutes until it's full?" "Is this cable starting to fray and dropping the output?"
There's a battery that visualizes all of these invisible-electricity frustrations as numbers. Today we're introducing the flagship model from Anker's top-tier "Prime" line: the Anker Prime Power Bank (20,000mAh, 200W).
Packed into a body the size of a soda can is enough power to run two MacBook Pros simultaneously, plus a "smart display" that hits every gadget-lover's sweet spot. This is the ultimate evolution of the power bank.

The biggest appeal of this product is the color display embedded in its side. Press the power button and the screen lights up. It shows not just "remaining battery (%)" but also "current input/output wattage" and "estimated time until fully charged" — all in real time.
The moment you plug in a cable, watching the numbers leap up — "20W... 45W... 65W..." — gives you the same rush as watching the tachometer in a sports car. "Oh, this new cable charges faster." "The PC is under heavy load, so power draw is up." Everything is visible at a glance. This is the moment when the simple act of charging transforms into entertainment.

It looks about the size of a 350ml can, but inside it's a monster. With two USB-C ports and one USB-A port, it boasts an astounding maximum total output of 200W across all three.
A single port can deliver up to 100W, enough to fast-charge high-spec laptops like the MacBook Pro. Even better, when two PCs are connected at the same time, it has the muscle to supply 100W to each (200W total).
With this in your bag, there's no more frantically scanning the café for "a seat with an outlet." A park bench, a regular Shinkansen seat — anywhere becomes your office.
| Charging the Battery Itself Is Also Lightning Fast

The Achilles' heel of high-capacity batteries has always been "how long it takes to recharge the unit itself." But this model supports input (charging the unit) at up to 100W as well.
With a 100W-compatible charger, it goes from empty to full in about 75 minutes. Even on those mornings when you realize "I have an early start tomorrow and I forgot to charge it!" you can get it back to a usable level while you're getting ready. The capacity is 20,000mAh — enough to fully charge an iPhone 14 about 3–4 times or a MacBook Air about once. And critically, it's still within the limit for airplane carry-on. A perfectly judged capacity.
| For Nomad Workers and Gadget Enthusiasts

This battery becomes a "holy grail" for the following kinds of people:
- Nomad workers who carry laptops like the MacBook to work on the go
- People who always carry multiple devices — smartphone, tablet, earbuds, and more
- Those obsessed with "charging speed" who want to pair it with the best cables and chargers
- People who want a high-output, high-capacity power source on hand for disaster preparedness
The price is around ¥19,990. Two thousand yen — er, twenty thousand yen — for a power bank takes some courage, but when you consider that you no longer need to carry your PC's power adapter and that you're completely freed from charging-related stress, the value is more than justified.

The Anker Prime Power Bank has changed the very concept of a battery. It's no longer just a tank that stores electricity — it's a control center that manages and regulates it.
Inside your bag is a vast reserve of energy, powerful enough to run a PC, and you can check its status with your own eyes anytime. This "overwhelming sense of omnipotence" may just be the single greatest reason to own this gadget.
