The K&K Jumpstart 990681 Jump N Carry 660 12 Volt Jump Starter is the ideal entry-level professional grade unit. This durable, yet lightweight, jump starter has terrific power output. Its ability to hold a charge for long time periods means that you don’t have to hunt down another vehicle to jump start yours.
The internal battery of the Jump N Carry 660 is a sealed lead acid (AGM) battery with a self contained 500mA charger. It provides 1700 peak amps of starting power at 12 volts. That makes it almost twice as powerful as many other lower quality competitors.
This Jump N Carry unit has 46″ heavy-duty #4 cables and the clamps have plastic covers that snap on when not in use. It also has a “cigarette-lighter” style socket to power small electronics and accessories. The built-in, color-coded voltmeter on the front of the unit lets you know the level of charge on the battery. When it needs charged, just plug it directly into a wall socket.
At 18 pounds, the K&K Jumpstart 12V Jump N Carry 660 jump starter is lightweight. It also has a slim design that makes it easy store away. It also comes with a one year limited warranty. The bottom line is; if you need the most power in a jumper starter without all the bells and whistles, this is the one to buy.

I own the jump and carry 660. I have jumped buses with the Cummings ISM (high compression) engine with this thing. If this jumper doesn’t make your motor crank then you have another problem besides a dead battery.
This unit is not an entry level unit. It is the unit preferred by the majority of professional technicians in North America and has made its reputation as an exceptionally durable jump starter that provides extreme power, as noted by another commenter. It features the Clore PROFORMER battery, specifically designed for vehicle jump starting, and packs 425 CA (1700 Peak Amps) of jump starting power.

I’ve had this unit for a few years and it is extremely convenient to have a jump start unit that actually works. I had a dead boat battery and used a fully charged Wal Mart charger and it would not spin the engine (Merc 260, 5.7 liter) fast enough to start. But the JNC 660 did and saved the day. But the best use I get out of the unit is during September PSU football games…. we use the JNC 660 and a power inverter to power a regular household blender to make frozen margaritas and daiquiris! The JNC 660 makes more frozen drinks on one charge than we can consume. Now that’s versatile!
