Charging MBP 13 with phone charger?

[GMac11]

I have tried some searching on the web but there are many conflicting opinions although it's difficult to find anything pretty recent.

The short question is will I do any damage to my MacBook or phone charger if I use it to keep the MacBook topped up?
I'm not too concerned with actually charging the thing as such as I assume it would be fairly slow but was thinking more for when I take it away with me or sat in the office and it's already charged from home would a mains phone charger keep it safely at full battery?

It would save me having to always remember to pack the actual charger as I'll always have my Pixel USB-C charger with me anyway.

Thanks.

I believe the new models can be charged from a battery and probably a phone charger as a result. It is going to be very slow! Older models can’t be charged this way.

You're not going to do any damage. It might work to add some charge over night, but you're not going to get any significant charge

I plug my 15" 2017 MBP Touchbar into my Pixel 2 charger to keep it topped up. No reason it'd damage either, PD is a two-way thing so the power draw is negotiated.

Get yourself a £35 Anker charger that has 1 x USB-C and 4 x USB-A ports. For a MacBook to be charged, the charger needs to have PD (Power Delivery). I know because my Dell USB-C does nothing for my MacBook (i.e. it won't even see it as a charger and won't charge).
