These come in very handy

You will never go wrong with having one of these behind your seat or in your trunk do you know how many people I have given boost with thses charger I don't boost anyone in my car because it could mess up your car but with these chargers you can boost a truck no problem I've dine it several times and then one tome the battery on my scooter when out I boosted it with this little charger no problem I thought to myself this won't boost your truck it need more power but it worked very happy with my purchase
