Question:	Can i jumpstart my suv
Answer:	The 71331 will jump start your SUV
Question:	Will this charge a completely dead battery ? Most newer car battery chargers need the battery to be above 2 volts for the charger register it
Answer:	Thank you for your inquiry ABORTED CHARGE If charging cannot be completed normally, charging will abort. When charging aborts, the charger’s output is shut off and the BOOST/CHARGING (yellow/orange) LED will flash. Do not continue attempting to charge this battery. Have it checked or replaced. DESULFATION MODE Desulfation could take 8 to 10 hours. If desulfation fails, charging will abort and the BOOST/CHARGING (yellow/orange) LED will flash.
Question:	Can this charger be use in a car socket
Answer:	You should only hook up this charger to the battery terminals. The cigarette lighter or accessory socket is typically fused at about 10 or 15 amps, so a fast charge through it would likely blow the fuse. It might work for a slow or trickle charge, but I don't recommend it.

User questions & answers

Question:	What is the warranty for th
Answer:	The user manual does not say anything about slow charging; it might charge the battery to a point if connected to it but it won't be slow. The car battery charger can charge small electronic devices via USB ports, but the charging circuitry that controls, monitors and limits the amount of current that goes to charge these devices is in the small electronic device itself. Customer support might be able to give you a better answer. The customer support number for the car battery charger is listed as 1 (888) 965-5888 in the user guide.
Question:	does this work with optima yellow top battery
Answer:	The cables are about 8 inches long not including the clips. However since the power pack is only a little larger than a cell phone it is easy to get it within a couple of inches of the battery posts so the cables do not have to be long to reach. That is the great thing about these little starters....they work without having to have space to maneuver a car or to need long cables.
Question:	Why does it say not to charge a dead battery in the warnings? Is that not what it’s meant for
Answer:	It charges using a provided USB-C cord but you must provide the wall or auto charger.
Question:	Charger says to connect cables when they are connected
Answer:	The instructions say at least 20%.

User questions & answers

Question:	Why is it not recommended to keep a trickle charger hooked up all the time
Answer:	beats me. i keep mine hooked up from 12/31 to 4/1 and only then do i take it off. my understanding is that you do not need to disconnect it-it powers down on its own, but you mught want to find the user nistructions and check me on that. good product if youre not in a hurry
Question:	how fast does it work
Answer:	if your battery is low it may take up to 3 0r 4 days since it's a low amp charge and designed to keep the battery at full charge once it's at full charge. This charger is super for use when you don't drive the vehicle a lot and it sits for any length. it can be used on the battery in the car or taken out, once it's on it can stay plugged in all winter of summer just unplug it when you go driving. If the car stays outside they make a waterproof model. If your looking for a fast charger this is not what you want, if you do buy this make sure it's the 12 volt model ... hope this will help you
Question:	Why is this not available in California
Answer:	Charge for free! Buy a low wattage solar battery charger/maintainer at Harbor Freight instead because it works very well maintaining the battery charge provided that the battery is fully charged before hooking up this solar charger.... it will only maintain the charge. Not made to fully charge a discharged battery. Point the solar panel southwest to get the most out of the sunlight during daytime. I have used this $9.99 if on sale gadget for years now on my boat and car and has not failed me yet. It comes with all the hook up accessories needed. I have not used the boat for 2.5 years at a time and the gel battery is as good as when I installed it 7 years ago. My car wet cell battery also is as good as when I first installed it and I only use the car abroad every 12 months when I am in town for 3 weeks. Car or Boat batteries Gel or not will not last it's lifetime if it is always discharged and recharged. Maintaining the charge is key to it's longevity. Good luck! No need to blame anybody. The State of California is an environmentally conscious state and that is a good thing for everybody.
Question:	Can this be used to charge an AGM battery
Answer:	Stupid me, but don't all lead acid batteries use the same chemistry? I've read only that 6-cell lead-acid batteries should never use a charging voltage exceeding 14.4 volts, since water will begin to H2 gas and O2 gas above that. You risk explosion and loss of electrolyte beyond that. Explain why this is different for AGM, Flooded, and Gel batteries!

• 【Portable Charger】Built-in smart charging port, which provides faster charging speed for your portable electronic devices. What's more, with the added DC output charging port, this compact power pack can charge laptop and vehicle equipment easily.
• 【Upgraded Jumper Cables with a LCD Screen】Unlike traditional car jump starters, its high quality and gilded intelligent jumper clamps do not only provide all-around protections but also design a LCD screen on the cable which has a built in voltmeter in it so you can see the strength of your battery without even having to plug the cord into the charger.
• 【Type-C Charging】Equipped with type-C cable, this device provides 2 charge modes with high charging speed to make it truly easy to use. It can be recharged with type-C cable and 5V universal adapter (not included, but phone charger adapter is suitable). Or you can directly plug the type-C cable into USB charging ports. It solved the problem that other jump starters equipped with wall charger just can be recharged via socket.
• 【Super Flashlight】The ultra-bright LED flashlight has 3 illumination modes; a flash light when you're in the dark, a strobe light to attract attention, and an SOS signal flash when you're outdoors and in need of emergency help.

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

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!
