4000A Car Jump Starter – 4000 AMP Peak Jumper Box, 51.8Wh Power Bank 12V Battery Charger, 7.2L Gas / 5.5L Diesel Engine, LCD Display, Emergency Lights
4000A Car Jump Starter – Jumper Box for up to 7.2L Gas and 5.5L Diesel
This 4000A car jump starter is a high-output booster pack: the supplier rates it at 4000 amps peak and lists it for 12V petrol engines up to 7.2L and diesel engines up to 5.5L. It has a 51.8Wh battery that also works as a power bank, an LCD display and an emergency light with three modes. Easy Life Markets sells it for owners of big-engined vehicles who need more than a pocket booster can give.
Engine size is what decides how much current a starter motor needs. A lawn mower will turn over on almost anything. A large V8 pickup or a diesel motorhome needs a serious burst, and it needs more still when the weather is cold and the oil is thick. That is the gap this unit is meant to fill. If jump starting is new to you, the jump start article explains the method and the safety points before you ever need to do it at the roadside.
Where the Facts on This Page Come From
The supplier gives no written specification for this product. Every figure below is read from the supplier's product images. Most of those images show the unit marked "TENKER ET05 Jump Starter 12V". One banner image shows a housing with a different marking, so we go by the printed figures, not by that one picture.

What Comes With It
The photos show the jump starter with a clamp lead carrying one red and one black clamp. The supplier has no written packing list. If you need to know which charging cable or case is in the box, ask us before ordering and we will find out.
Which Vehicles It Is Listed For
The supplier's chart says it "fits all 12V common vehicles" and gives these examples by engine size:
- Lawn mower – 1.0L
- Motorcycle – 1.5L
- Car – 2.5L
- SUV – 4.5L
- Pick-up – 6.5L
- RV – 7.2L
The limits are 7.2L for petrol and 5.5L for diesel. Check two things on your vehicle before buying. First, that it has a 12V electrical system. Many heavy trucks and some large motorhomes run on 24V, and this unit is not for them. Second, that the engine size is within the limit for its fuel type. Both are in the owner's handbook.
The Ten Protections Named by the Supplier
- Spark-proof protection
- Reverse polarity protection
- Short-circuit protection
- Low voltage protection
- Over voltage protection
- Over-temperature protection
- Reverse charge protection
- Jump starter time-out protection
- -4 °F / 140 °F temperature bearing
- "Zero-damage" protection, in the supplier's words
Reverse polarity and spark-proof protection are the two you will be glad of in the dark, when it is easy to put a clamp on the wrong post. They reduce the risk from a mistake. They do not replace checking the terminals before you clip on.
Power Bank and Light
The 51.8Wh battery is described as a power bank as well as a starter. The USB output is 5V/2A, which charges phones, tablets, earbuds, dash cams and similar devices at a normal rate. The pack itself recharges through a Type-C input at 5V/2A or 9V/2A, so it can be charged from a USB-C charger. The LED has three modes for working under the bonnet or signalling. The LCD shows the remaining charge as a number, and the supplier's image shows it reading the output as well.
How to Use It
- Check the LCD. Charge the pack if the level is low.
- Switch off the ignition, lights and accessories.
- Connect the clamp lead to the pack.
- Clip red to battery positive (+) and black to negative (–).
- Start the engine. Keep each attempt short and leave a pause between attempts.
- Once the engine is running, remove the clamps, black first.
Follow the instructions supplied with the unit where they differ. Never join the clamps together, and keep the pack away from moving belts and fans in the engine bay.
Storage
The supplier's image claims 12 months of standby. Treat that as the outside limit, not the plan. Check the display every three months and top the pack up, and always recharge it after a jump start. Keep it between -4 °F and 140 °F (-20 °C and 60 °C). In hot weather that means the boot or under a seat, not the dashboard.
Who This Jump Starter Is For
It suits owners of large petrol pickups, SUVs and motorhomes, drivers of diesel vehicles up to 5.5L, and anyone who looks after a mix of machines, from a mower and a motorcycle to the family car. It is more pack than a small hatchback needs, though it will work on one.
Common Questions
Will it start a diesel? The supplier lists diesel engines up to 5.5L on 12V systems.
Is it a TENKER product? The unit in most of the supplier's photos is marked TENKER ET05. The supplier does not name a brand in writing, so we report the marking as shown.
How is it charged? Through the Type-C input, at 5V/2A or 9V/2A.
