Newell Vayu 27000mAh Power Bank: 140W to Power a Full Day

The Newell Vayu is a 27000mAh power bank that delivers up to 140W through USB-C, which is enough to charge a laptop, not just a phone. It has three ports, two USB-C and one USB-A, so you can charge a laptop, camera, and phone at the same time. A backlit TFT screen shows exactly what is going on, and a built-in flashlight covers you when the lights go out.

For anyone shooting on location, editing on the move, or travelling with a bag full of USB-C gear, it is a serious energy reserve that still fits within airline carry-on limits. This guide explains what the capacity and the 140W mean in practice, how the power is shared between ports, and who the Vayu suits.

What 27000mAh Really Gives You

Capacity is quoted in milliamp-hours, but energy in watt-hours is the more useful number. The Vayu's 27000mAh works out to 97.2Wh. That figure is measured at the battery cells, and some energy is always lost as the power bank converts it to the voltage your device needs, so you get a little less than that in practice.

Newell estimates it at about four to five full charges of a typical smartphone, or one full charge of a MacBook Air-class laptop, with enough left over to top up a camera or tablet. Your own results will depend on the battery size of your devices, but for a full day in the field or a multi-day trip, it removes the usual question of which device to charge first.

Why 140W Changes What You Can Charge

Most power banks are built for phones and cap out well below what a laptop needs. The Vayu supports USB Power Delivery 3.1, which allows higher voltages than older USB-C chargers, and Newell lists both USB-C ports at up to 140W (28V at 5A). That is enough to charge USB-C notebooks, an iPad Pro, handheld consoles, and drones at full speed, not just keep them ticking over.

The USB-A port adds fast charging up to 22.5W for the many devices that still use it. To get 140W into a laptop, the laptop itself must support that level, and you need a USB-C cable rated for 140W or more.

Three Devices at Once: How the Power Is Shared

All three ports work at the same time, and the Vayu's energy management hands each device the power it asks for. The key number is the total: 140W across all three ports combined. Charging a phone or a camera battery barely dents that, but if a laptop is drawing its full rate, adding other devices means the 140W is split between them.

In practice that is rarely a problem. A laptop, a camera battery, and a phone together usually ask for less than 140W, and the Vayu sorts out the split automatically.

Recharging the Vayu

The Vayu also accepts up to 140W through USB-C, which is why Newell rates it to recharge in under two hours. To reach that speed you need a charger that supports Power Delivery 3.1 at 140W, and a USB-C cable rated for the same. No cable is included in the box.

A slower charger still works, it just takes longer. Our Newell GaN chargers top out at 100W from a single USB-C port, so they will recharge the Vayu well, but not at the full 140W rate.

The Screen and the Flashlight

You do not have to guess how much charge is left. The backlit TFT display shows the charge level, voltage, and live output, so a glance confirms whether your laptop is pulling its full rate. It also shows the cell temperature and the number of charge cycles, which is far more useful than a row of blinking LEDs.

The built-in flashlight is the kind of extra you forget about until you need it. It has two brightness levels and an SOS mode, handy for a night hike, load shedding, or finding cables at the bottom of a bag in the dark.

Cleared for Carry-On

At 97.2Wh, the Vayu sits under the 100Wh threshold that TSA and IATA guidelines generally allow in hand luggage without airline approval. Power banks must travel in your carry-on, not in checked bags. Each airline sets its own rules for spare batteries, so check your carrier's guidelines before you fly.

Newell Vayu Specifications

Who the Vayu Is For

This is a mobile power station, not a pocket top-up. It suits filmmakers, photographers, streamers, and travellers who run a laptop and several devices through a long day and cannot afford to go flat: an edit on a train, a live stream on location, or a multi-day shoot away from mains power. If you only ever charge a phone, a smaller power bank will be lighter to carry.
