The weight and size of the battery is directly proportional to its capacity, for this reason you should firstly determine what is the minimum capacity that you require.
This will depend on various factors, but mainly on the capacity of your own phone battery and what do you want the portable battery to achieve e.g. partially charge your phone for emergency use only or fully charge your phone once or fully charge your phone multiple times.

You have posted this to a Macintosh forum. Do you want to use the battery with a phone? If so, this post is in the wrong forum and I can move it to the appropriate iPhone forum. Either way, more information about device you want to power would help people give you better answers.
