Reinventing Jump Starting.
The Genius Boost GB70 by NOCO is a portable, mini, pocket sized lithium-ion jump starter for 12-volt lead-acid batteries. BOOST HD is designed for larger vehicles, like trucks and SUVs, as well as many diesel engines. Integrated heavy gauge cables efficiently transfer massive power surges. The 12V "IN" port allows extremely fast in-vehicle charging. The 12V "OUT" port will power any 12V accessory, like a tire inflator, light, inverter, and more. NOCO's jump starters are powered by a High-Density NOCO Element lithium-ion battery that can hold a charge up to one year without usage, and handle over 1,000 cycles with proper charging.
Zero Sparks; Zero Compromise.
Noco designed the Genius Boost to be a safe and effective jump starter that anyone can use. The NOCO GB70 is built with a set of top-of-the-line processors, thermal sensors, and power management devices; all without sacrificing performance.
Charging the Genius Boost Jump Starter
Connect the Genius Boost Jump Starter using the included USB Charge Cable to the USB IN port and the USB car charger. Your Genius Boost Jump Starter can also be recharged from the optional USB plug. The USB IN port is rated at 2.1 Amps to ensure safe and efficient charging of the internal lithium battery. Due to FCC regulations, we recommend not to charge and discharge the unit at the same time.
The time to recharge a Genius Boost Jump Starter will differ based on the discharge level and the power source used. Actual results may vary due to battery conditions.
I bought this jump starter a little over two years ago I use it all the time for myself and for other people this charger has never let me down. It says it holds a charge for about a year if you don't use it. Well don't think I will ever get to know that because I always use it and I just charged it even when I don't have to the thing is just great never seen anything like it over the years I have bought many jump starters and they only last me maybe a few months and go bad. Yes I am very very impressed with this jump starter. I've also had a lot of my friends to buy this charger all of them are still telling me how wonderful the jump starter is. All I can say it is a great product and if you don't have one you need to get one. Sorry I am just writing this review because I wanted to know that this product was all it said to me and now it's a fact that it is.
As expected, and more!
Product came quick. The only disappointment was lack of the 120 volt charge adapter. . For the price it should be included.
This is the best jump box I have owned. I use a jump box daily and this one is very powerful, have jumped several completely dead Powerstrokes off with it. Small and strong.
I had to use this jumper on a 2003 Honda Accord with a bad starter and a bad battery. Was strong enough to crank the battery while the starter gasped its last gasp. Also lightweight and compact. Very powerful though due to lithium technology. Would highly recommend.
I haven't yet used this "in anger" so to speak, on a low battery. However, it charged up fine after receiving in the mail. After reading the instructions, it is designed to be almost fool proof. I did order the two-way splitter to check the GB70 voltage. The GB150 version has a voltage readout included, but costs $100 more.
The unit dose what its supposed to. BUT it should be made clear before ordering it only works with lead-acid batterys
