Yes, and it is safe. I did charge my 15" MBP from various sources - power banks and adapters (USB Port of a Tesla Model S was my favorite), and it can take around 13W. Just make sure that your adapter supports 10-15W, 5W is quite slow. Unfortunately the port does not support Quick Charge.
When idling, the system consumes around 6W, charging will be impossible while using with something more cpu/gpu intensive.
And if you decide to cheat and try to connect a second charger, it will not combine the power, but instead choose the one with higher power rating.
TL;DR: It's possible. It's safe (It'll cause 100% use on your adapter, might heat it up). Perfect for emergency use or when weight is important. Not useful if you plan to do extensive work.
Answer from mspasov on Stack ExchangeSafe to charge macbook with USB Type A to USB Type C cable? - Ask Different
what charging cable is right for my mac?
Daily reminder, You don’t need to carry a Magsafe cable with you. All you need is just a USB-C to USB-C cable. It can charge your Macbook and other electronic devices too. Real portability. One cable is more than enough

But not sure which cable i should buy. Can you please help select the correct cable for my mac. Thanks
My charging cable is falling apart and I need a new one. I was thinking about buying something more durable and longer, like braided cables (USB C to USB C).
I am wondering if there are different types of cables (like there are HDMI ones, or some USB C cables not being able to transmit digital picture) I should watch out for? If there are, what would be the option?
This question is specifically for people who have the option to charge with both MagSafe or USB-C (charging with Thunderbolt counts as using the USB-C connector in this scenerio).
