Hi All,
Looking for a Fast Charge Keychain Power bank that charges at 18W minimum.
I would like the keychain power bank to at least give me half a full charge.
So, a 2000mah one then at 70% efficiency should be about 50% of the battery.
And a 4000mah one should then give me 1 charge.
Also willing to consider small pocket ones in the 5000mah range.
Budget is $30. I own an iPhone 12 for reference.
I didn't end up getting a new big battery phone as per my other forum post.
