One of the Top 10 greatest vehicle gadgets I've ever purchased for any car or truck I've owned. A must have especially for roadtrips and or if you have an older battery. Bought this for our 4th Gen Toyota 4Runner. Due to circumstances beyond our control, we had to use this for six months every time we started the truck as the battery we wanted wasn't available. Kept the NOCO charged properly and it never failed. DRIVING TIP. buy one of these for a long road trip. Also, buy one for everyone you care about that drives, especially if they drive at night or when the clocks change and it gets dark earlier in the evening, late afternoon. You won't have to worry their car battery died and they're sitting in a parking lot or side of the road. It's also great for an emergency charge of your phone or other mobile device. It also has a nice bright LED lite and LED flasher. However, I'd recommend NOT getting into the habit of using it for your mobile devices as you might just need it one day to jump start your car and might not have recharged it in a whlle. Buy another type of extra battery charge for your mobile and entertainment devices. Use this just for emergencies. They have small amp models and larger ones too. With this type of emergency device, bigger is better. Get at least the 1000 amp, I'd love to test out the other products NOCO makes. This one is spot on perfect.
