The best power bank for small USB-C laptops 

The Gravity 45 is a powerful 20'000 mAh power bank is equipped with the latest Power Delivery (PD) technology, meaning it can power USB-C laptops as well as phones.

The 45W USB-C PD output allows you to charge laptops with power ratings up to 45W - usually notebooks and small laptops - at full speed. The Gravity 45 can also recharge bigger laptops (such as a Macbook Pro) - a little slower - as long as they are equipped with a USB-C charging port. 

 

 

 

Weighing only 470g, it weighs just a little more than a normal 20'000mAh power bank. It is therefore a great choice for anyone who wishes to have backup power for both their phone and their laptop.

 

 

Of course, this power bank is also compatible with all smartphone brands (iPhone, Huawei,  Samsung, Xiaomi) and with tablets (e.g. iPad) and consoles (e.g. Nintendo Switch).

Can I use Gravity 45 laptop power bank for air travel?

Yes! The Gravity 45 laptop powerbank has a total capacity of 74Wh which means it is legally allowed for air-travel in your carry on luggage. The maximum legal limit is 100 Wh (27'000 mAh). 

How to charge a laptop with the Gravity 45 power bank?

Press on the power button to turn on your battery. Using the cable, plug the USB-C port into the Gravity 45, and connect the other end of your cable to your device. It should start charging automatically within a few seconds. 

 


How to determine my laptop power ?

To check the power required by your laptop, check the rating of your laptop charger to determine the required power input. You can determine the power of your usual laptop power supply by finding the output current and output voltage, and then multiplying both numers (e.g. 19V x 3,42A = 65W). 

If your laptop requires 45W, the Gravity-45 will work perfectly. If your laptop requires more power and has a USB-C port, it will charge but at a slower pace. If it requires more than 45W of power or if it doesn't have a USB-C input, check out the Sunslice Gravity 100 model which would be more suitable. 


Can I charge the Gravity 45 with my standard phone charger?

Yes, you can. However, the 45W quick charge input of the Gravity power bank will charge at its best when using a wall charger that can charge up to 45 Watts.

We offer the Gravity 45 Pack for a very interesting price, including :

the Gravity 45

-the Emperion 65 wall charger that can deliver up to 65W from its USB-C output and also integrates 2 USB QC3.0 outputs. This charger is the most adapted to charge the Gravity 45 at very high speed. It is very small and can also be used as your phone and tablet charger as it can charge 3 devices at once

A USB-C cable

 

This will make you able to obtain the best performances when using the Gravity 45.
