Double capacity travel charger

This 20000mAh power bank delivers roughly twice the energy of standard packs while staying within the 77Wh airline carry-on limit. It can recharge an iPhone 16 up to three times a Galaxy S24 up to 2.9 times and a Google Pixel 9 up to 2.3 times making it suited for weekends away or business trips.

Four built-in cables six simultaneous outputs

Integrated cables include three output leads and one input lead covering USB-C Micro and Lightning style devices so no extra cords are needed. The unit offers six total outputs and four input paths allowing up to six devices to charge at once while the bank itself recharges through any input with automatic power adjustment.

20W PD fast charging headroom

A USB-C port supports up to 20W Power Delivery pushing an iPhone 16 to 50 percent in about 45 minutes far quicker than basic 5V 2A charging. The 20000mAh reserve handles multiple phone and tablet top-ups comfortably but will not sustain high-draw laptops or extended multi-device sessions beyond its rated capacity.

Questions about this item

Will the 20000mAh battery hold its capacity after repeated daily charging cycles?

The 77Wh lithium-ion pack is rated for typical cycle life; capacity will gradually reduce over hundreds of cycles but the unit remains compliant with airline carry-on limits under 100Wh.

What limits sustained 20W PD output before the power bank throttles?

Total output adjusts automatically across the six ports; thermal protection will reduce power if internal temperature rises during prolonged multi-device charging.

How much heat or fan noise appears when all six outputs run continuously?

No fan is fitted; the casing dissipates heat passively so surface temperature rises but stays within safe limits for handheld use.
