Yah that can be a hassle, well there are a number of Booster Packs you can buy just to be safe. The have outlets on them too so you can use it for a radio and or anything else. They are very handy, but my advice to you is just buy find one on sale around your area, they are alway on sale right now because it is summer. I have worked for dealerships for a long time and the we use battery booster packs all the time, and even if you buy the best one it will not last any longer than a mid range booster pack. So find a great deal on one that is 40% off, use that, the money you would spend for a snap on booster pack, it would do more functions then you would need. Where as the standard one with two outlets, some have radios, and even little dome lights to help you see. They are great, but do not spend alot money one, you can find them at any auto store, or walmart, Meijer for a great price under $50
