11 best battery jump starters

Battery jump starters, also known as jump packs or jump boxes, are essential automotive accessories designed to provide a portable and convenient way to jump-start a vehicle's dead or depleted battery. They are a valuable tool for emergency situations and are widely used by motorists, especially in cases of a dead battery. Here are key points about battery jump starters:

  1. Functionality: Battery jump starters are compact, self-contained units that store electrical energy in an internal battery.They can deliver a high current output to boost a vehicle's battery and start the engine when it has insufficient charge to do so on its own.

  2. Portable Power Source: These devices serve as a standalone power source, eliminating the need for another vehicle or external power supply to jump-start a car or other vehicles like motorcycles, boats, and ATVs.

  3. Battery Types: Battery jump starters are equipped with different types of batteries, with lithium-ion (Li-ion) and lithium-polymer (LiPo) batteries being common choices. These types of batteries are lightweight, compact, and hold a charge for extended periods.

  4. Capacity: Jump starters come in various capacities, indicated in terms of ampere-hours (Ah) or milliampere-hours (mAh). A higher capacity typically means the device can provide more jump-starts before needing recharging.

  5. Safety Features: Many jump starters incorporate safety features such as reverse-polarity protection, short-circuit protection, and overcurrent protection to prevent damage to the vehicle's electrical system or the jump starter itself.

  6. USB Ports: Some models include USB ports or other power outlets that allow users to charge or power mobile devices like smartphones and tablets, making them versatile emergency power sources.

  7. LED Lights: Many jump starters have built-in LED lights with various modes (e.g., flashlight, SOS, strobe) to provide illumination in dark conditions or serve as emergency beacons.

  8. Charging Options: Jump starters can be recharged via AC power outlets or 12-volt DC adapters, ensuring they are ready for use when needed.

  9. Maintenance: Regular maintenance involves keeping the jump starter charged and periodically testing it to ensure it functions correctly. Most models have indicator lights or displays to show the battery's charge status.

  10. Size and Weight: The size and weight of battery jump starters vary, with smaller, more compact models being easier to carry in a vehicle. Larger models may offer more power but can be bulkier.

  11. Usage: Battery jump starters are used for various vehicles, including cars, trucks, motorcycles, and recreational vehicles. They are particularly useful in situations where access to traditional jumper cables and another running vehicle is not available.

In summary, battery jump starters are indispensable tools for motorists, providing a portable and self-contained means to jump-start vehicles with dead or depleted batteries. Their compact design, safety features, and additional functionalities like USB ports and LED lights make them valuable accessories for handling emergency situations on the road.

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: 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.

User questions & answers

Question: can these be charge under 220v (outside US
Answer: i have had no problems leaving in a glass box - car with windows all the way up. think it may drain the internal battery a touch but nothing serious. instead of having 5 day charge, you may have 4 days 22 hours or so
Question: Has anyone used this product to jumpstart a full-size SUV with success
Answer: I dont have this one, but I do have the last version, and after taking mine apart, here is what I can say. While there are lights on the front that tell you when the battery is full, I have found not proof or evidence of any float in it to keep it from over charging. My opinion, while it should not hurt much to leave it is for a short period of time after it is fully charged, I would keep somewhat in mind to make sure that it is not left charging for extended lengths of time. Doing so can damage the battery in it. If you do damage the battery in it, replacement batteries can be bought and installed for around half the price of one of these. I just replaced the battery in mine, and for mine, I found some cheap, made in china ones for about $30. I found one that was made in the USA for just a few dollars more. All that there is to replacing the battery is to take the screws out that hold the front and back together, which should be around 8 screws, the two pieces should come apart, and the battery should be right there. The battery will be attached to the wires by a nut and bolt on each terminal. That is it. and just in case you are wondering, the battery in mine was a 19ah, 12v battery.. but the 18ah ones are easier to find. The size of mine is about 6.5" x 7" x 3", or something like that. and mine is the same overall type/design/rating as this one. Just without the USB ports. but you would have to verify that they still use the same battery if you do choose to replace yours in the future.Also, as to the charging thing. Some people say to charge it once a month. Personally, i feel that is a bit much. I say to charge it when it is getting a bit low. Why do I say this.. because these types of batteries do not really loose much power over time, if not being used. Even the manufacturers of the batteries for these say that you only need to top the battery off, once every 6 to 12 months, if the battery is just sitting on the shelf. So I see no reason why, if you are not using the jumper at all, why you would need to charge it every month. If the battery is at, say 90%, then it is still fine to leave alone (unless you know you are going to need it very soon, and quite a few times at that), but if it gets to maybe 75%, I say charge it to top it off. Dont forget, since the batteries in these are the same type as what is in a car, you just don't want to let it get too low. If you do let it get too low, that can ruin the battery, just like how it will in a car.
Question: What is the starting current for this device
Answer: For a battery of this size, I'd not go over 240 watt inverter. Actually, you can use any inverter (I got a 400 watt unit that came with a lighter plug as well as other wires), but I'd not connect up a load greater than that ~240 watts. I have at least 2 reasons. First, the lighter outlet that you'll likely want to use is for sure intended for under 20 amps (and maybe fused for only 10 amps). Secondly, the battery is likely rated "18 amp-hour" hinting it can give you 18 amps for 1 hour, or 9 amps for 2 hours, etc. For something needing just 1 amp at 120V the inverter will pull 10 amps at 12V from the battery making it last under 2 hours (or under 1 hour for 2 amps at 120V). I recommend against pulling power faster than it's rating (~20 amps) since I've seen statements in manuals like "Don't crank a car for even 5 seconds because the battery will overheat internally" and I think you're pushing your luck to expect more than that continuously.
Question: Is there a warranty? If so, how long
Answer: Mine wont. I have a Dodge 3500 5.9l....My charger is brand new and fully charged. It won't even hold a no load charge over night.

User questions & answers

Question: How many months/years life can i expect from this before it turns to junk
Answer: The operating temperature is -4F-140F. I would think that you would store it within that temperature range and be fine. There is nothing in the manual regarding storage locations
Question: So this should jump a 5.0L Ford truck correct
Answer: Yes. Pretty much all USB wall chargers are dual voltage (100 - 240 volts / 50 - 60 hertz), just check fine print on charger. You should just need a simple adapter for the country that you are going to. Normally the only things you need to worry about are hair dryers and curling irons. These are often single voltage 120 volts / 60 hertz (USA). You can buy travel versions with switchable voltage. You should not require a voltage converter. The DB Power 2500A has a capacity of 21,800 mAh, or (21.8 amp hours * 3.7 volts) = 80.66 watt hours / TSA limit is 100 Wh carry on only. Hope all this helps.
Question: how long is the cable? the car's battery and grounding spot are on opposite sides of the engine bay
Answer: yes, the product itself has 1 year warranty. But you can activate the warranty card to extend more 2 year warranty. I've already got the 3 year warranty confirmation from seller.
Question: How long will it hold a charge while not in use? (most batteries loose charge over a period of time even when they are not in use
Answer: I believe so. I've seen a technician myself before did it in my car while he was replacing a new battery on my car. I told the technician i want to keep the setting i did in my car; Radio channels, AC, panel instrument and it works.

Perfect Journey Companion in Toolbox

Intelligent cable designed with 8 kinds of protections to ensure operation safety for users: over current protection, short circuit protection, overload protection, over-voltage protection, over-charge protection, etc.

ATTENTION

1. Please read the instruction carefully and strictly follow the instruction before using the jump starter. Any wrong operation may cause damage to the jump starter or cannot get the car started.

2. Don't jump start any engine that exceeds the maximum displacement the unit can bear, or it will cause damages to the unit.

3. Your jump starter will perform best when its battery is fully charged. If less than 50% charged, it may not be able to start your engine.

4. Don't connect the positive and negative polarity together when it's power on. Don't crank the engine for more than 3 seconds. Allow the jump starter to cool down for at least 30 seconds after each jump-start.

Despite 8 kinds of protections of the cable, it also has a "DO" connector. With the connector, users can not connect the jumper cable with the battery pack if they are doing steps wrongly. So the battery itself will not provide any power while the wrong connection. Users can easily figure out the mistake and correct the steps. The safety use can be protected in this case even though sometimes you may carelessly reverse connected the jumper cable.
