A dead battery is a situation familiar to every driver. When the engine refuses to start and the low battery indicator flashes on the instrument panel, a special “lighting” device comes to the rescue. But what is it called correctly? In conversations, car enthusiasts use dozens of terms: from official to slang. This confusion often leads to mistakes when purchasing or using equipment.

In this article we will analyze all the options for names - from technically correct to everyday ones. You will find out how they differ jumper wires from boosterswhy power bank for a car is not the same as a portable charger for a phone, and what terms are used by professionals in car repair shops. And also - how not to run into a fake when choosing a device for emergency engine starting.

Official names: what manufacturers and GOSTs say

In technical documentation and auto parts catalogs, devices for starting an engine from an external power source are designated by strictly defined terms. The main one is jumper wires (or starter cables). This is a pair of thick wires with alligator clips at the ends that connect the discharged battery to the donor one.

According to GOST R 53170-2008regulating the requirements for starting devices, the correct names include:

  • 🔧 Battery jumper — the general name of the equipment class.
  • 🔌 Starter booster (from English booster) is a compact device with its own battery for starting the engine.
  • ⚡ Portable battery charger (PROM) — combines the functions of a booster and a charger.

Car service centers and spare parts stores often use abbreviations: PPU (starter charger) or PU (starting device). Important: term "cigarette lighter" does not appear in technical documents - this is a purely colloquial name that has stuck in everyday life.

Colloquial and slang names: what drivers say

In everyday life, car enthusiasts rarely use official terms. Instead, abbreviations and jargon are common and can be confusing to newbies:

Slang name What do you mean? Correct term
"Cigarette Lighter" Any device for starting from an external battery (wires or booster) Jumper leads/starter booster
"Crocodiles" Clamps at the ends of the starting wires Trigger clamps
"Power bank for the car" Portable booster with lithium battery Starter booster/PROM
"Charging for lighting" A device for recharging a dead battery (not for starting!) Charger (charger)

The danger of slang is that different devices can be hidden under the same name. For example, the phrase "I bought a cigarette lighter for my car" may mean:

  • 🔋 Jumper wires (for connecting to another car).
  • 📱 Portable booster (with its own battery).
  • ⚡ Charger (for charging only, not for starting!).
⚠️ Attention: If the seller offers you "universal cigarette lighter for all types of batteries" - this is a reason to be wary. This is often used to disguise cheap Chinese counterfeits that can burn out the car’s electronics.

Types of “lighting” devices: how they differ

All emergency engine starting devices are divided into three main categories. They are often confused due to their external similarity, but their operating principles and capabilities are very different.

1. Starting wires (starting cables)

The classic version is two thick wires (red and black) with clamps at the ends. Working principle:

  • 🔴The red wire connects to positive terminal donor and discharged battery.
  • ⚫ The black wire connects minus donor with mass (optional with a dead battery terminal!).
  • 🚗 After connection, the engine of the donor car starts, and then the engine of the discharged one.

Advantages: low price (from 500 ₽), ease of use. Disadvantages: Requires a second vehicle, risk of short circuit if connected incorrectly.

2. Starting boosters (jump starters)

Compact devices with built-in lithium-polymer or lead-acid battery. Examples of popular models: Carku E-Power Elite, Berkut JSL-12000, NOCO Boost Plus GB40.

How they work:

  1. The booster is connected to the discharged battery through special clamps.
  2. The device supplies a short-term high current (up to 1000 A), sufficient to start the engine.
  3. After starting, the booster can be turned off and charged from the cigarette lighter or outlet.

Pros: no need for a second car, can be used in a field or garage. Cons: high price (from 3,000 ₽), limited number of starts on one charge.

3. Starter-chargers (ROM)

Hybrid booster and charger. Examples: Hyundai HY 400, Autoelectrics T-1012. Can:

  • ⚡ Start the engine from the built-in battery (like a booster).
  • 🔋 Charge a dead battery from a 220 V network (like a charger).

Suitable for garage use, but bulky for constant transportation in the car.

- Booster battery capacity (from 10,000 mAh for gasoline internal combustion engines)

- Peak current (minimum 400 A for passenger cars)

- Availability of protection against short circuit and polarity reversal

- Compatible with the temperature conditions of your region

How not to make a mistake with your choice: what to look for in the store

When buying a device for “lighting up,” many focus only on the price, but this is a grave mistake. Here are the key parameters that determine reliability and safety:

  1. Wire cross-section (for jumper cables): minimum 16 mm² for gasoline cars, 25 mm² - for diesel engines. Thin wires heat up and melt.
  2. Cable length: optimally 3–4 meters. Short wires (less than 2 m) are inconvenient when parking cars.
  3. Clamp material: should be made of copper or brass, not aluminum (oxidizes quickly).
  4. Peak current (for boosters): for gasoline engines up to 2.0 l - from 300 A, for diesel engines - from 600 A.
  5. Reverse polarity protection: required! Without it, a connection error will lead to a short circuit.

Critical point: cheap boosters are often equipped with lithium-ion batteries without protection from low temperatures. At −20°C, such devices lose up to 50% of their capacity and may not start the engine.

Device type Minimum requirements for a passenger car Average price, ₽
Jump wires Section 16 mm², length 3 m, copper 500–1 500
Starter booster Capacity 10,000 mAh, current 400 A, short circuit protection 3 000–8 000
Starter charger Current 200A, charging function 12V/24V 5 000–15 000
⚠️ Attention: If the booster package says "suitable for all types of batteries", but specific parameters are not indicated (capacity, current, battery types), - this is a fake. These devices always have detailed technical specifications.
💡

Before purchasing, check to see if the booster comes with a storage case. Without it, wires and clamps will quickly become damaged in the trunk.

What happens if you reverse the polarity: consequences and how to avoid

The most common mistake when “lighting up” is polarity reversal, that is, connecting plus to minus and vice versa. The consequences depend on the type of device:

  • 🔥 Starting wires: instant short circuit, melting of wires, possible fire. At best, the fuses in the car will burn out.
  • 💥 Starter booster: failure of internal circuits, swelling of the battery (especially in cheap models).
  • ⚡ Car electronics: The generator, engine control unit (ECU) burns out, problems with the alarm system are possible.

How to avoid the error:

  1. Always connect red wire to positive, black - negative.
  2. On some boosters, the clamps are marked with symbols + and − - check them before use.
  3. Use wires with protection against polarity reversal (built-in fuse or light indication).
What to do if the polarity has already been reversed?

If the error is noticed immediately (before starting the engine):

1. Disconnect the wires immediately.

2. Check the temperature of the wires and clamps - if they are hot, do not reuse them.

3. Inspect the fuses in the car (especially F10 or F20 in the block under the hood).

If the engine was started with polarity reversal:

1. Disconnect the battery and check the generator for serviceability (measure the voltage at the terminals with the engine running - it should be 13.8–14.4 V).

2. Check the operation of the electronics (headlights, radio, power windows).

3. At the first signs of a malfunction (smoke, burning smell), contact a car service center to diagnose the ECU.

Myths and Misconceptions: What Really Works (and What Doesn't)

There are many myths surrounding “lighting up” a car. Let's look at the most common ones:

Myth 1: “You can light a cigarette while the donor engine is running”

❌ Reality: This is a big mistake. When starting the engine of a discharged car, the donor generator receives a sudden load, which can damage it. Correct order:

  1. Stop the donor engine.
  2. Connect the wires.
  3. Start the donor car, let it run for 5–10 minutes (to recharge the dead battery).
  4. Turn off the donor and try to start the discharged car.

Myth 2: "A booster can replace a battery"

❌ Reality: Starter boosters are intended only for short-term starting the engine. They cannot power the vehicle's on-board network instead of the battery. After starting the engine, the booster must be turned off - otherwise it will discharge in a few minutes.

Myth 3: “The thicker the wires, the better”

⚠️ Nuance: Thickness is important, but no less critical core material. Aluminum wires, even with a cross-section of 25 mm², conduct current worse than copper wires with a cross-section of 16 mm². Optimal choice - copper stranded wires with silicone insulation.

Myth 4: “You can light a cigarette from any car”

❌ Reality: You cannot “light” a car with:

  • 🚘 With a diesel engine (if your car is gasoline) - the starting current of a diesel engine is higher.
  • 🔋 A battery with a smaller capacity (for example, from Daewoo Matiz to Toyota Land Cruiser).
  • ⚡ Damaged electronics or faulty generator.
💡

The safest way to “light up” is to use a starter booster with reverse polarity protection. It eliminates the risk of damaging the electronics of both vehicles.

FAQ: Frequently asked questions about “lighting up” a car

Is it possible to “light” a car with the engine running?

No, this is dangerous for the donor generator. Correct algorithm:

  1. Stop the donor engine.
  2. Connect the wires.
  3. Start the donor for 5–10 minutes (to recharge the dead battery).
  4. Turn off the donor and try to start the discharged car.

Exception: if you have a modern booster with the function "soft start" (soft start), you can connect to a working donor.

How long does it take to “light up” a dead battery?

The time depends on the degree of discharge:

  • 🔋 If the battery is partially discharged (voltage 11.5–12 V), 5–10 minutes of recharging from the donor will be enough.
  • 🪫 If the battery is completely dead (voltage below 11 V), it will take 15-20 minutes or use a booster.
  • ⚡ If after 3 attempts to start the engine does not start, the problem is not in the battery (the starter or generator may be faulty).
Is it possible to “light up” from a car with a different voltage (for example, 24 V from 12 V)?

No, this will lead to failure of the electronics. An exception is special starting-chargers with a voltage switch (for example, Berkut JSL-2412).

Dangerous combinations:

  • ❌ 12 V → 24 V: not enough power to start.
  • ❌ 24 V → 12 V: fuses and electronics of a 12-volt car will burn out.
How often can I use the starter booster?

Modern lithium polymer boosters (e.g. NOCO GB70) can withstand up to 20–30 launches on one charge. However:

  • 🔋 After each use, the booster must be charged (even if it is “almost full”).
  • ❄️ At temperatures below −10°C, the booster capacity drops by 30–50%.
  • 📅 The service life of a high-quality booster is 3-5 years (with proper storage).
What to do if after “lighting up” the car stalls?

This is a sign that:

  1. The battery does not hold a charge (needs replacement or diagnostics).
  2. The generator does not charge the battery (check the voltage at the terminals with the engine running - it should be 13.8–14.4 V).
  3. There is a current leak in the on-board network (for example, due to a faulty alarm system).

Actions:

  • 🔧 If the car stalls immediately after disconnecting the wires, repeat the “lighting”, but let the engine run for 10-15 minutes at idle speed.
  • 🚗 If it stalls after a few minutes, go to a car service urgently (the generator may be faulty).
