What to Look for in a Portable Car Battery Charger?
As not all engines are the same, and they require more or less power depending on the vehicle type, you need to get the right jump starter considering this factor. Also, there are power packs of different capacity, features, and functions where you need to focus as well.
Apart from going through the best portable battery charger reviews, be sure to look for the following key specs before you buy one.
The power output of a jump starter determines how effectively it can power up your battery. Most manufacturers mention the peak amperage or current that the power pack is able to deliver; whereas, some show it in watts.
When a portable battery charger shows that it can deliver 1000A to jump-start a car, it means, this is the maximum amount of power the pack can discharge to the dead battery. The power output should be sufficient enough to power up your vehicle battery and some of the initiating mechanisms of the car; crankshaft, engine, etc.
So, there are two factors related to this power output. First, the battery charger provides power to recharge the battery itself. That means how long it will take to get the battery fully charged.
Secondly, it also delivers power to the crankshaft to make it rotate so it can fire up the engine to get the vehicle moving.
Apart from this ampere rating, you also need to consider voltage to get an overall idea of how capacity of the battery chargers.
So, now the question is, how do you know what the right power output is for your car battery and other initiating mechanisms? You will need to check the user’s manual to find out how much power your car requires to start the engine.
Be sure to check the specifications of the vehicle battery as well. If your vehicle requires a 12-volt battery, make sure the jump starter got 12-volt amperage to start the engine.
Cranking Amps Rating
This specification will tell you how capable the vehicle battery chargers are when it comes to powering up a dead battery in real-life situations. Cranking amps rating is also known as ‘cold cranking amps’ among expert car owners.
The term basically indicates the amount of power the jump starter can generate within 30 sec at a temperature of 0-degree Celsius or 32-degrees Fahrenheit. And the jump starter should be able to maintain a minimum power of 1.2-volt per cell for a 6-cell 12-volt battery.
With this amount of power, you can start the car engine even during winter. If you live in an extremely cold area, be sure to check ‘cold cranking amps,’ which is particularly rated for cold areas at –17.8-degrees Celsius or 0-degree Fahrenheit. For a 6-cell 12-volt battery, the jump starter should maintain at least 7.2 volts.
To be able to jump-start a car faster, you must ensure the starter power pack comes with a cable that has thicker wires inside it. Thinner wires take longer to recharge the battery.
The jumper cables should have 8-gauge wiring, at least. Lower the number, the thicker the wires are, and the faster it will jump-start your vehicle.
Portable car battery chargers come with several useful features that make the deal worthwhile. There are USB ports that allow you to charge your smartphone and other devices. Some models feature USB 3.0 ports to charge your devices faster.
Having a powerful LED flashlight will make things easier to deal with in dark and low lights. Some flashlights can be used as an SOS and strobe light for convenience.
You can diagnose the battery and see the status if the jump starter comes with an LCD display. This feature comes very handily to acknowledge the battery condition.
Frequently Asked Questions
Q: Can you leave a car battery charger on charging for too long?
Ans: Overcharging can damage yourbest portable jump starters if it doesn’t have any overcharging protection. If you have to charge it for long periods, consider getting battery chargers that turns automatically off once the battery is full, or a trickle charger that charges very slowly.
Q: Is 300-amps enough to start a car as jump starters?
Ans: For most sedan cars that require less power, 300A of peak start will be enough if the temperature isn’t very low, and the battery isn’t dead for months. However, it’s recommended to buy a car jump starters with at least 400amps.
Q: Does CCA – Cold Cranking amps matter on a battery?
Ans: If you live in a cold area, CCA will matter a lot. The higher the CCA, the faster your engine will crank.
Q: Can I put a higher CCA battery in my car?
Ans: If your car requires a 500A battery, consider getting a battery of 600A or higher. Since this CCA drops over the year, it’s better to get one with a higher amount of amp.
Q: How many times can a car battery be recharged?
Ans: Under normal circumstances, the alternator can fully charge the battery thousands of times as soon as the car starts moving. However, if it’s about recharging a dead or flat battery using a jump starter, after five to six cycles, the battery is pretty much toasted.
The best portable car battery charger will provide you a few weeks of the window until you get the new battery for the car. Before getting a charger, be sure to check what amount of power your car requires to start the engine, and the specification of the car battery so that you don’t end up buying the wrong one.
