The classification of this equipment is carried out according to various criteria. One of them is the power type. Depending on this aspect, best jump starters are divided into two main groups: plug-in and portable.
Plug-in Jump Starters
These are devices working from any standard power source with a voltage of 220V. Due to their dependence on an external energy source, plug-in models are more suitable for use in car repair shops or garages. Their area of use is limited by the length of power cable or extension of a cord coil.
Portable Jump Starters
These models are equipped with their own battery and are absolutely mobile, compact, and perfectly suited for the needs of an ordinary car owner. However, they have limitations on the capacity and power of the built-in battery, on which a possible number of engine starts will depend. Portable devices do not require any special maintenance, but it will be necessary to follow the manufacturer recommendations as for charging.
As you can see, both types of best jump starters are characterized by versatility. That is, with their help, you can both start an engine with a dead battery, and charge a rechargeable battery.
BEST JUMP STARTERS BUYING GUIDE — WHAT TO LOOK AT?
The primary purpose of best car starters is to light up a vehicle’s battery in an unusual situation. A related purpose of their use is to charge gadgets like smartphones, laptops, cameras, etc. That’s why it is essential to choose the right device. All the criteria given below will be useful to consider.
As a rule, in most cars, the onboard voltage is 12V. Only some models of jeeps and trucks may be an exception, where the tension of standard power network supply is 24V. Some models of the best car battery jump starters out there are equipped with a voltage switch and can operate in two or three modes – 6, 12 and 24V.
According to jump starter reviews, the power of the starting current should not be less than the minimum value consumed by the starter. Depending on the viscosity of the oil, the starter may require up to 400A to turn the crankshaft. Under normal conditions, this value is half as much, about 200A. The simplified approximate value of the current consumed by a starter can be calculated by multiplying the battery capacity by three. Do not be afraid of the failure of the starter when applying excessive current power as it won’t intake more than needed.
In addition to the starting current, manufacturers often indicate a peak one, which is several times higher than the nominal value. The best car battery jump starter can generate a peak high power pulse for a split second at the very first moment of the engine start. Nominal power steadily holds for three seconds. At this time it is recommended to turn the starter, with intervals of three minutes to restore the battery capacity of the booster.
This value indicates how many attempts can be made to start the engine of a vehicle. For example, the cheapest models have a capacity of 15-17 mAh, which approximately corresponds to three or four attempts to start a frozen car engine. More powerful jump starters for sale can withstand up to 10 or more startup cycles. After that, you will need to recharge the battery of the device.
As jump starter reviews say, sometimes it is necessary to give preference to models that are more potent in parameters. A more expensive option, in this case, will be fully justified by the increased reliability and extended service life of the device.
Charging from 220 V, cords for phones and clips for batteries are essentials. The length and cross-section of the power cable should not scare you – short and thin wires have the same low resistance as a large cross-section. In addition to accessories of the basic plan, it would be nice to have an adapter for charging booster from the cigarette lighter.
All lithium-polymer batteries have a limited number of charge cycles. Not every manufacturer indicates precisely how much. On average, the battery can withstand up to 1,000 cyclic loads.
Li-Po batteries are aging. If there is no need for a device, store it in a warm room with a charge of 40% of the nominal value. Taking into account jump starter reviews, in these conditions, it will live longer.
THE BEST JUMP STARTERS. FINAL ADVICE
To sum it up, the best car jump starter is a useful thing, especially for the winter season.
Based on our research, it is possible to state for sure that Clore Jump-N-Carry JNC660 170 is one of the best jump starters 2020 has to offer.
