User questions & answers

Question:	Can i use this to power a cpap machine
Answer:	Yes! I have tried on MS Surface 3 and MS Surface pro 4, and it works on both of them.
Question:	Most of these charge super slow using micro usb. does this one support fast charging
Answer:	This stylus doesn't have replaceable tips. Tips are not replaceable in this stylus. Tips costs as much as the whole stylus itself. So, it is better to get the whole thing.
Question:	How many months does it hold a charge
Answer:	My iPad and iPhone has tempered glass. It works perfectly with both of the apple devices.
Question:	Is it ok to use a 5 volt 3.1 amp charger with this
Answer:	They're about 4 3/4 inches. I know you didn't ask... but if your plans are to use this stylus on any devices with protective covers (which I'm sure most people have on one or more of their treasured devices nowadays)...don't waste ur money on this brand...choose another...cause this iBart brand does not work, as advertised, if you have a protective cover. It doesn't stick to the screen and just slides off whenever you try to make contact. I have better success using my fingers. Wished I had seen honest reviews about this particular issue before I purchased mine. I know they are not expensive...but now I'm stuck with 9 more useless stylus that I can't even give away.

User questions & answers

Answer:	It's noisy. it's ok for topping off a tire but when needed to put in 10 lbs or more it over heats, . Mine smoked and not working after 3rd use.
Question:	Do i need to plug in to use the air compresor
Answer:	Yes, it is quiet enough. I think the sound of the fan is completely acceptable.

User questions & answers

Question:	Can the battery be replaced
Answer:	I leave mine in the hot car in the summer in 100°F weather and also -20°F. Never had a problem
Question:	Am I able to charge this unit with a portable solar power panel & run my laptop on it for at least two hours
Answer:	It will hold 75% of each charge for a year or longer but we recommend topping it off every 6 mo if it hasn't been used, just to make sure it is fully charged if needed.
Question:	Other than jumping a car with a dead battery, what makes this one so much better?, does this one do more than the others on Amazon at a lower Amps vs. 1700?, what does the 1700 amps give you extra? and how does the auto charge work
Answer:	I found this on the NOCO faq page.... What types of batteries can Boost jump? All Boost models (except the GB500 Boost Max) can jump start 12V lead acid batteries only. This includes wet, gel, maintenance free, enhanced flooded battery, and absorbent glass mat batteries. The GB500 Boost Max is capable of jump starting 12V and 24V acid batteries.
Question:	Will it jumpstart an AGM Optima battery or any Deep Cycle Battery
Answer:	Yes it will start up any (vehicles) car battery. However (in error) when I received my order of the GB-40, I had only checked it; by turning it on and looking to see what the power display showed (as far as voltage lights). I should have charged it, even though it showed full charge; when I had to use it maybe a month later (as my battery in the car) had finally given up; the booster saved me but then showed low power had remained on the booster GB-40. The car's battery needed to be replaced the next day. The GB-40, saved me!

User questions & answers

Question:	What does a blinking red light mean, when connected to a car battery
Answer:	No, once you jump it you remove it from the battery. I charge it with the outlet cord. I have been able to get a few jump starts with a single charge. It is great as back up while boating and Jeeping.
Question:	Can this device be used to jump start a vehicle through the cigarette lighter adapter? (using a separate male cigarette lighter adapter
Answer:	These packs will provide 12V power, but it's hard to promise you that it will always get you going. A lot will depend on things like did a light get left on for 2 hours while you went to a movie or all night long fully draining the battery? I've done a test myself with a similar pack where I disconnected my car battery (to pretend it was dead) and tried the pack alone. My 4 cylinder car did start, but cranked so slowly I didn't think it was going to as I held the key for 3 seconds. With that experience I doubt this alone could handle a truck with 2 batteries that are both fully drained and even an OEM rep from Clore suggested their next bigger unit (the JNC950). To be honest with you I'd not buy the 950 for $250 when I can get a 35 amp-hour battery like it has for $70 (which leaves me $150+ to buy jumper cables & a charger separately), but that's just me. In any case, don't get too sold on the "1700 peak amps" labels since these are not that big a battery (just as it weighs 15 lbs versus 45 lbs for a real car battery, that's the ratio of power I expect).
Question:	What size plug should be used to connect to your DC output coaxial Jack? 5.5 x 2.5mm
Answer:	I have mine stored on it's back and have experienced no issues. I have not encountered any battery leakage storing it in this position.
Question:	Does it have a boost button feature
Answer:	It comes wit a short 4' 2 prong cord that plugs into the back (male), you can use an extension 3 prong cord also. I recent;y bought this unit because I had purchased a JNC660B for work that performed beyond my expectations. It was used left uncharged in the heat of AZ for months and several times. Over a 5 year period it had few charges left in 100+ degree heat and is still going strong.

User questions & answers

Question:	When you use the jump box to start a vehicle does the running vehicle in turn charge the jump box
Answer:	I've been using mine for almost 2 years and it still works great. I can get 6 or 8 jumps for a V8 engine without recharging the device- Quite impressive considering we used to have to have those huge spare batteries or jump from another car. Everybody should have at least one of these!
Question:	How does this unit fair on diesel engines, like 5.9/6.7 cummins / duramax or powerstroke engines, does it have enough juice to get em going
Answer:	I started my Ford F-350 6.8L V10 twice and it was still 75% charged. This was at 8500 feet temp about 10F. I love this little thing!
Question:	Jnc770r - can i store this unit in my vehicle laying on its back or side? will the battery leak when stored in these positions
Answer:	These products with the short cables are intended for direct connection to both terminals of the battery. This is NOT a recommended practice when jump starting with booster cables between vehicles, because the high current potential could cause sparking (when connecting) which could ignite battery gases. That's where you need the good (away from battery) ground spot to make the last connection safely. These products however don't present that hazard when connecting.
Question:	Does this unit need an extension cord to charge
Answer:	The battery doesn't retain the charge too good, if unused. And the reporting on the LCD is misleading: After a full charge and months of non-use, it still indicated 91%. When I connected the jumper cable to begin to jumpstart the car, it suddenly dropped to 68% ! And that was NOT sufficient to jumpstart a size 24F battery (4.3L gas engine, if that makes any difference), even though the green LED light was flashing (then turned solid) to indicate the battery charge was ok to jumpstart. I charged it for a few hours to get back to 100%, and then the jumpstart worked. So, always check real battery charge level with jumper cable plugged in.
