Ultra-Compact 20000mAh Power Bank

The WOOJONG 20000mAh 65W power bank delivers high-capacity portable charging in a remarkably small form factor. It is designed for professionals and travellers who need to keep laptops, tablets and phones powered throughout the day without carrying bulky equipment. Three output ports allow simultaneous charging of multiple devices. It suits anyone who values minimal bag weight and maximum energy density.

65W Fast Charging Thermal Performance

The unit supports up to 65W output for rapid charging of compatible laptops and phones. In typical use it can charge a MacBook Air 13 to 41% and an iPhone 15 to 56% within 25 minutes. PD 3.0 and QC protocols manage power delivery efficiently across two devices at once. Low-current mode ensures safe charging for small accessories such as earbuds and smartwatches without overheating or excessive noise.

Broad Device Compatibility & Included Cable

The power bank works with a wide range of USB-C devices including laptops, tablets, Steam Deck, and smartphones such as iPhone 15, 16, 17 and S24 models. It also supports low-draw accessories that many chargers cannot handle. A 100W USB-C to USB-C cable is included for immediate use. Buyers who need wireless charging or more than three simultaneous ports should consider other solutions.

Questions about this item

How do I connect the INIU 20000mAh power bank to my MacBook Air 13 and what is the common mistake?

Use the included 100W USB-C to USB-C cable plugged into the power bank's USB-C output port; the common mistake is using a lower-rated cable that cannot deliver the full 65W.

What maintenance or replacement will the INIU 20000mAh power bank need over time?

The internal lithium-ion cells gradually lose capacity after hundreds of charge cycles; the unit is not user-serviceable so replacement of the whole power bank is required once runtime drops below your needs.

What limit appears first when charging a laptop and phone together at 65W continuously?

The 20000mAh capacity depletes quickly under 65W combined load, so runtime becomes the limiting factor before thermal throttling occurs.
