10 best power banks for a car

The capacitor-type booster is designed by the manufacturer for emergency starting of the car engine when the battery is inoperative. Designed for vehicles with a gasoline engine up to 4.5 liters and a diesel engine up to 3 liters with a 12-volt on-board network. There are no batteries in this starting device, and supercapacitive capacitors (ionistors) play a key role. Capacitor charge storage provides a guaranteed start of the motor with a battery discharged up to 5% or without a battery (with charging from a battery either from the cigarette lighter of another car, or from charging with a micro USB connector). Customers like the reliability of the model, the ability to start with a completely dead battery and a virtually endless resource. Although the price of the device is high.

An inexpensive model of a power bank for waking up engines with a 12-volt on-board network with a discharged battery. Compact but capacious device suitable for cars and SUVs. The manufacturer claims a starting current of 200 A and a peak current of 400 A. Drivers notice that under such loads, with 2-3 attempts to start, the wires can overheat. But often 1 time is enough to start the car. The device is packed in a convenient plastic case, where all the necessary parts fit - clamps with wires, a splitter cord with plugs. The model can serve as a power bank for mobile gadgets.

A compact external battery with a declared capacity of 18000 mAh with a starting current of 250 A and a peak current of 1000 A. This resource is enough to start cars, small trucks and SUVs.The device has a very low level of self-discharge - for a year of "idle" it will keep its charge within 80-85%. The model has 8 degrees of protection - from overcharging, overcurrent, overheating, high voltage, power problems and others. The device is absolutely safe. The start jumper is packed in a convenient case. Among the shortcomings, users note the lack of fast charging modes.

Universal car starter suitable for starting petrol (up to 7L) and diesel (up to 6L) engines with 12V and 24V batteries. It can serve as a temporary power source in the absence of a battery, as well as a power bank for mobile devices. The device has 6-stage protection: against overheating, overcharging, overvoltage, short circuit, reverse charge and reverse polarity. Drivers speak of this model as a powerful starting device that really helps to get out in the winter after a long downtime or with a dead battery. Not everyone manages to start up the first time, but a combination of factors, and not one power bank, is responsible for this.

An inexpensive power bank with a small peak current of 300 A (starting current - 150 A) is designed to start gasoline engines up to 1.5-1.8 liters and slightly smaller diesel engines. Designed to interact with a 12 V battery. A good option for motorcycles and small cars. The starter gadget is also useful for charging a smartphone or tablet. The power bank is equipped with an LED flashlight with modes. It does not illuminate the entire car, but spotlights in the dark can sometimes come in handy. The kit includes terminals for starting engines, but, to the inconvenience of consumers, there is no charger to return power to the power bank.

The brand's most powerful lithium polymer starter is designed to start car and truck engines.It brings motors with 12 and 24-volt batteries back to life, can become a power source through the cigarette lighter port for powerful car devices (refrigerator, compressor) or be used as a power bank for mobile devices. The booster has a built-in flashlight - quite powerful. It can be used to illuminate the workplace for several days without recharging. In general, this starting device demonstrates minimal voltage loss when starting a car and a low level of self-discharge. Car owners in the reviews talk about the easy engine start with Aurora 40, but complain that the launcher cannot be stored in the cold - it will not start the car. Some believe that at this cost, the device could have a stronger case.

An inexpensive external device for charging and starting will eliminate the need for owners of cars, motorcycles and SUVs to light up from a neighboring car. The model supports powering devices through the cigarette lighter, charges mobile devices (USB 5B) and supports car systems when the battery is disconnected. The built-in flashlight has a strobe mode that allows you to disorient the enemy or signal your location.Drivers say that the power bank is enough for 3-4 launches, after which the device must be charged. Of the inconveniences - only the impossibility of launching if the launcher lay in the cold. In such cases, it should be warmed up a little.

The external starter belongs to the professional class. Produced for starting diesel engines up to 10 hp. QDSP fast start technology delivers up to 5 times higher inrush currents than many other power banks (1000A nominal, 2000A peak). Designed for 24V batteries. ROM is useful not only for buses and trucks, but also for cars and motorcycles. A capacity of 28,000 mAh is enough for several revivals of a dead car battery and up to 20 times charging a smartphone. Drivers note the quick start of serious engines in the cold, as well as the good quality of the cables and the reliable fixation of the alligators. But short wires give them inconvenience.

A small but powerful starting device that holds a charge perfectly and allows you to instantly start a car with a dead battery. The manufacturer intended it to work with gasoline engines up to 4.0 liters and diesel engines up to 2.0 liters, under the 12 V on-board network. The external battery can also work as a power bank for mobile devices. Of course, you can’t charge a laptop from it (output voltage is 5 V), but a smartphone or tablet is easy and fast. There is a boost mode, however, its activation button is small and not very convenient to turn on.

Car owners like the combination of quality and price of the launcher, its equipment and case. They also note the well-thought-out protective functions of the device - from short circuits, overtemperatures, from errors with plus or minus, from overcurrent and its reverse flow, overvoltage and overcharging.

The high power lithium jump starter provides up to ten car starts without recharging the booster. It is designed to save gasoline engines up to 5 liters and diesel engines up to 3.2 liters. Built-in cigarette lighter adapter allows you to share power with car accessories. Smartphones and other devices can also be charged. By the way, it has 2 USB ports, so you can charge 2 gadgets at the same time. Drivers in the reviews note that the power bank practically does not discharge when the car is started - after 2-3 starts, the battery level remains almost the original. The device has a thorough protection - against reverse currents, polarity reversal, short circuit and complete discharge. The degree of protection of the housing is IP64 - dust and water splashes do not get inside.
