The best power bank for a small laptop 

The Gravity 45 is a powerful 20'000 mAh power bank is equipped with the latest Power Delivery (PD) technology, meaning it can power small 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 (like Microsoft Surface). The Gravity 45 can also recharge bigger laptops (such as a Macbook Pro) as long as they are equipped with a USB-C charging port. 

Weighing only 350g, it weights no 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?

First, check what kind of input plug your laptop requires. Then, choose the right cable option in the scroll down menu above. If you are not sure about choosing the right cable, please contact us and we will gladly assist you to make the right choice.

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. 

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 and doesn't have a USB-C input, you will need to upgrade to the Sunslice Gravity 100 model.
