18800mAh Car Jump Starter M43 – Automobile Emergency Start Power Source, 12V Mobile Power Bank, Large Capacity Car Battery Booster

18800mAh Car Jump Starter M43 – 12V Emergency Start Power Source

This 18800mAh car jump starter is the M43 model: a compact red and black 12V emergency start power source with a digital display, two USB charging ports and a built-in LED light. The supplier's parameter sheet gives it a 300A starting current and a 600A peak. Easy Life Markets offers it as a simple, low-cost pack for drivers of ordinary cars who want to be able to get going again without waiting for help.

Packs of this size are normally built around a rechargeable lithium battery. The supplier does not name the exact cell type for this model, but the general background is in the lithium polymer battery article, which covers the kind of cells normally used in small jump starters. What matters to you as an owner is that these batteries hold their charge for months, weigh very little, and need topping up now and then to stay ready.

Packing List

The supplier lists:

• 1 x host (the jump starter unit)
• 1 x battery clamp lead
• 1 x data cable
• 1 x manual

One supplier photo also shows a zip carry case next to the kit. The case is not in the written packing list, so we do not promise it. If the case matters to you, ask us to confirm before you order.

One of the supplier's images mentions Quick Charge 3.0, while the parameter table lists the USB output as 5V/1A. Where the two disagree we go by the table, which is the more cautious figure.

A Tour of the Unit

The supplier's labelled photo points out these parts:

• Digital display. Shows the charge level as a number.
• Power switch. Turns the unit on.
• Start port. The socket marked with a car symbol at the end of the unit, for the clamp lead.
• Two USB ports. For charging a mobile phone.
• Power charging port. For recharging the pack itself.
• LED light. Set into the end of the housing.

How the LED Light Works

The supplier gives the sequence on the parameter sheet:

1. Long press the switch for 3 seconds to turn the light on.
2. Long press again and it flashes.
3. Press again for SOS rescue mode.
4. Press again to turn it off.

What Size of Engine Is It For?

The supplier does not publish an engine-size limit for the M43, so we will not invent one. What we can say is where a 300A starting current and 600A peak sit against the other packs we sell. They are above the small 400A-peak pocket units listed for petrol engines up to 2.0L, and below the 800A and 1000A packs listed for 6.0L petrol or 3.0L diesel. On that basis we would treat it as a pack for ordinary petrol cars, not for large diesels, vans or pickups. If you drive something bigger, pick one of the higher-rated packs linked below, or send us your engine details and we will suggest one.

It is for 12V systems only.

Cold Weather

One of the supplier's images describes the pack as suitable for low-temperature starting in severe cold. No temperature figure is given, so we cannot quote a working range. Our practical advice for winter is the same as for any lithium pack: keep it indoors or inside your coat until you need it, because a warm pack delivers more current than one that has spent the night in a frozen boot.

Using It to Start the Car

1. Check the display. Charge the pack first if the level is low.
2. Switch off the ignition, lights, heater and radio.
3. Plug the clamp lead into the start port.
4. Clip red to battery positive (+), then black to negative (–).
5. Start the engine. Keep each try to a few seconds and wait between tries.
6. When the engine is running, unplug the lead and remove the clamps, black first.

Do not let the clamps touch each other, and follow the manual in the box where it differs from these steps.

Charging and Storage

• The input is listed as 5V 2A, so a normal USB phone charger rated 2A is what you need. The data cable is included; a mains adapter is not listed.
• Charge it fully before the first use and after every jump start.
• Check the display every two or three months and top it up.
• Keep it out of direct summer sun inside the car.
• Stop using it if the case swells or it becomes hot while charging.

Who This Pack Is For

It suits drivers of small and mid-size petrol cars, anyone on a budget who still wants a display instead of guesswork, and people who want a spare pack for a second car. At 170 x 38 x 85 mm it fits in a glovebox.

Common Questions

Is 18800mAh the real capacity? It is the figure on the supplier's parameter sheet and in the option name. We have not measured it.

Will it start a diesel? The supplier gives no engine rating. For a diesel we recommend a pack that is listed for diesel engines.

Can it charge my phone? Yes, the unit has two USB ports and the table lists the USB output as 5V/1A, which is a slow but steady charge.
