Jump start packs

[cuneus]

My 2005 V70 2.5T seems to to have a short battery life if the ignition is on but not started (ignition off and it holds charge OK)

e.g. at the station dropped my phone, switched the ignition on but not started - eventually retrieved the phone - a few minutes: car would not start

Called recovery who also tested the battery and said it was fine

So any suggestions for an emergency jump start pack ?
