Hi,

I am not sure if the Anker 25600mah battery(15watts IIRC) or RAVPower USB-C Power Bank 26800mAh PD Portable Charger(30watts) messed with my Macbook 12" battery. I got a new one from Apple and it has been working fine but I would like to avoid a repeat on my Macbook 13" 2019 2.8ghz.

Would it be safe to top up the MBP 2019 battery during light usage using the Ravpower Power Bank 26800mAh PD Portable Charger since it is only 30watts whereas Macbook Pro charger is 61 watts.

I am waiting to get the Sanho 27,000mAh HyperJuice USB Type-C Power Delivery 3.0 Battery (Space Gray)
but hoping my Ravpower can work for a while more.

Please let me know if you charge your macbook via battery and if you ever had problems?

Thanks.

Here's the one I've been using for over a year without any issues sold in the Apple stores with my MBP -->https://www.apple.com/shop/product/HLHW2ZM/B/mophie-powerstation-usb-c-xxl-universal-battery?fnode=7a2f8b078ac6c23b4d36461821b5a7fb74a7edb9279da50468006d11f9e42896976d918c719c6a63ab2351f169294762bc80033a99330c96676b6dfc12e8c761bbd951dd7e6428be5c2bb5101f7b2b8e2a92ddc49ff71834b24f7a461ec19f9e

There's also a bigger 3XL version in the store

Yes, the MBP uses USB for charging now so it will accept any USB power pack or adapter. Obviously, ones that support USB-C and Power Delivery a high wattage output will be needed to realistically charge the laptop.

There is a lot of flexibility in charging on the new models. It is great.

I had the same worry and nope. PD is negotiated between the devices so the MBP or any device really will request as much as it can handle. For USB C cables, you may want to make sure they are able to handle PD. I get Anker cables that are rated for 80W.
