Razer Power Bank  2020 Latest Updated Review

The Razer Power Bank is equipped with Intelligent device charging and is able to instantly identify the type of device that is plugged in and a fast charge for all devices

Razer introduces Power Bank smart charge accessory. The Razer Power Bank isn’t your average portable power bank, the power bank has both USB-A and USB-C support and is compatible with devices with USB Type-C ports including laptops.

With the Razer Power Bank, the Razer Blade Stealth 12.5-inch gaming laptop can have an extended battery life of more than 15 hours.



The Razer Power Bank is equipped with Intelligent device charging and is able to instantly identify the type of device that is plugged in.

A fast-charge feature unlocks up to six hours of battery life in a Blade Stealth in less than two hours of charging.

Additionally, Qualcomm Quick Charge 3.0 allows users to power up their compatible mobile devices up to four times faster than conventional charging.

The Razer Power Bank is small enough to fit in most pockets and matches Razer’s laptop design aesthetic with a black CNC aluminum casing.

Equipped with a large 12,800 mAh capacity battery, the Razer Power Bank is an ideal traveling companion for all mobile power needs.


It’s just not a Razer Blade product unless it’s swathed in stately black CNC aluminum. So I wasn’t in the least bit surprised when I took the Power Bank out of its packaging.

Keeping with the Razer aesthetic, the Power Bank even has the three-headed snake emblem stamped on the top of the device, minus the eerie green glow. That doesn’t mean, however, that the Power Bank is just a slab of black metal.



Most portable chargers have only one or two ports with which to give and receive power. Not so with the Power Bank. Razer very wisely added three ports to the top and bottom of the charger.

The top end of the device is where you’ll be charging your smartphone, headphones and, in some cases, laptop. You’ll find a pair of USB 3.0 ports along with a USB Type-C port.

The bottom is where you’ll replenish the Power Bank’s battery with either a USB Type-C port or a microUSB port. The Power Bank can also be charged via an optional AC adapter.


As a person who can’t stand being without my smartphone, I have almost as many chargers as headphones.

That said, the Power Bank might be one of the strongest chargers I’ve had the pleasure of using.

Thanks to its 12,800 mAH battery, the device can charge up to three products simultaneously, which came in handy when I needed to charge a pair of wireless headphones, my Nintendo Switch and my Samsung Galaxy S8+.

But the Power Bank made its biggest impression when I attached it to a couple of laptops: the Razer Blade Stealth and the Lenovo ThinkPad Yoga 370.

We ran the Laptop Mag Battery test, which consists of continuous web surfing over Wi-Fi.

By itself, the Blade Stealth lasted 5 hours and 11 minutes, but with the Power Bank attached, the ultraportable tapped out after 10:10.

That’s an additional 4 hours and 49 minutes. When we switched over to the Yoga 370, the Power Bank extended the battery test for an additional 3 hours and 2 minutes, bringing the laptop’s original time of 7:25 to 10:27.

Battery life is already one of the Razer Blade Stealth’s most compelling features, but if you need to eke out even more power from the ultraportable’s cells without plugging in, Razer’s got you covered with a new external power bank.

The black brick  is designed to extend the Blade Stealth’s battery life past 15 hours.

It’s got a 12,800mAh battery and a USB-C port, which means it can deliver impressive amounts of power to just about any laptop that supports charging via USB-C.


How do you charge the battery itself? Well, you’ve got a number of options.

If you want to charge it as quickly as possible, you’ll want to buy Razers separate 45W USB-C charger. This can take the battery from completely dead to full in less than 12 hours. But if you already have a USB-C device, you might not need it.



How much extra juice can you get with this battery? Well, that depends. The battery itself is 12,800 mAh. However, it’s worth noting that this is a single cell lithium battery.

If you’re calculating the amount of power you can use to charge a phone, the numbers will line up. Phones also use single cell lithium batteries. But other devices, particularly laptops or larger USB-C electronics, can use multiple cells.
