CA measures this at 32 degrees F, while CCA measures this at 0 degrees F. The higher the number the more jump starts a unit will be able to do before needing a recharge.Ĭranking Amps (CA) and Cold Cranking Amps (CCA): CA and CCA measure much lower than the peak amperage rating because they measure continuous power over 30 seconds. It just won't deliver as many jump-starts as a fully-charged device.Įnergy (Wh): The total energy that can be stored in a unit, measured in watt-hours (Wh), indicates how much juice a unit can ultimately output. In other words, a half-charged jump starter will deliver the same power, every time, until it's drained. Most of them can only deliver high amperage for somewhere between two and five seconds, followed by a power cut rather than 30 seconds of sustained amperage.Īdditionally, we reached out to the experts at Batteries Plus for some more clarification, and they said jump starters will typically list an approximate number of starts the fully charged device can complete until it needs to be recharged. However, portable jump starters with lithium-ion batteries cannot deliver high amperage for very long due to the risk of thermal runaway-a phenomenon that causes lithium-ion battery cells to go into an uncontrollable, self-heating state, which can result in fire. For units powered by lead-acid batteries, peak amperage is an initial jolt of power that the device delivers, typically for 20-50 milliseconds, followed by 30 seconds of sustained amperage, which is categorized as Cranking Amps (CA) or Cold Cranking Amps (CCA), depending on the temperature. The higher the peak amperage rating, the more powerful a jump starter is (at least initially). Peak Amperage (Current): This is the figure most manufacturers boast loudest about-but it doesn't necessarily mean bigger is better. If you have a fleet of vehicles that need some help waking up in the morning, get a portable power station.īut how much power does your portable jump starter need for your vehicle? It can be confusing trying to decide with all of the numbers and power ratings out there, such as peak amperage, amp hours, cranking amps, and so on. If you just want one to keep in the car in case of an emergency, get a portable jump starter. The question of which kind you need depends on how you'll be using it. Portable jump starters are small and easy to store in your trunk (or even glovebox), while portable power stations can be kept in the garage for repeated use. There are two basic types of car jump starters: portable jump starters and portable power stations. When complete you can unplug the micros and charge your cellphone, or add the Lightning adapter for an iPhone.Show more Things to Consider When Shopping for a Jump Starter This is an compact and great charger that can also charge your Android or iPhone.Īttach magnetic leads to battery, plug into a USB-A charger to charge your 18650. If the magnets stuck to the batteries better, it would be awesome. I had to use other magnets between the charger terminals and the batteries to get the terminals to stay on in any meaningful way. Although the magnets stick together aggressively, I was disappointed that they do not maintain a more aggressive contact with the batteries. I was looking for a super compact portable charger. Simple efficient design, Inwould buy again.įrederic Nott from brooksville, FL United States Features a nice built-in LED light and charging indicator.Ĭ from Prescott Valley AZ, AZ United States I keep this in my work bag so I always have the ability to charge my MT10C's battery on the go/in the car. Johnny Utah from San Jose, CA United States With three adjustable brightness levels, the LC10 emits up to 10 lumens when plugged into a wall outlet and 6 lumens when powered by a 3400mAh battery.Ġ of 0 people found the following review helpful: An included lightning adapter adds support for Apple devices!Īdding even more functionality to the LC10 is a mini backup light you can use for reading, lighting up the tent or emergency situations. Use the standard micro-USB 2.0 output to charge your devices like cell phones, cameras and headlamps from a charged battery quickly and conveniently. Need to charge something else? When paired with a charged battery, the LC10 can be used as power bank. Charging progress is reported through a simple to read indicator light while internal safety protections prevent overcharging and short circuits. Compatible with many common li-ion and IMR battery types, this minimalist charger uses two magnetic contacts to quickly charge your batteries via any USB power source. Take the NITECORE LC10 magnetic USB battery charger on your next trip and say goodbye to bulky charging solutions.
