If you own vehicles, you should keep a booster pack in your garage. Booster packs are mini jump starters that are designed to deliver a quick burst of 12-volt electricity when your battery is dead. They are much more convenient than jumper cables (jump leads), because they don’t rely on another vehicle to provide power. The ES5000 by Booster PAC is one of the best booster packs available. With a peak of 1000 Amps, it has enough power to jump start any 12V car battery. This portable jump starter is also very compact and easy to use! You can also consider buying the Ever start jump starter, it is a very popular product.

Top Features:

  • Battery: The Booster PAC ES5000 features a sealed lead-acid battery with 1000 peak amps and 225 cranking amps. This is enough to start most passenger vehicles and light-duty trucks, including cars, SUVs and pickup trucks.
  • Cables: The Booster PAC ES5000 features 50″ cables that terminate in heavy-duty clamps for enhanced durability and safety. The cables also have a built-in safety switch that prevents sparks from forming when the clamps touch each other or any metal object.
  • Charger: The unit ships with a charger that can recharge the battery in less than three hours. – Case: The Booster PAC ES5000 has a very durable case that protects the internal components from damage and impact. 

How much does ES5000 cost?

The Booster PAC ES5000 12 volt jump starter is a heavy duty and portable jump starter. It has the ability to crank up most car engines, even in cold winter weather. The ES5000 can be used for multiple purposes besides jump starting vehicles. It is a great back up power supply for powering other devices such as laptops, cell phones, and many other electronics. For example, you would use this if you are camping and run out of battery life on your cell phone or laptop. You can also use it to inflate tires or air mattresses or any other inflation device that runs off 12 volts.

The ES5000 is a fairly affordable unit considering all the features it includes. It includes a long cable with clamps so you can attach it to the battery of your vehicle that needs jumped. This alone sells for fifty dollars at Sears or Auto Zone. Also included is an adapter so you can charge your electronics while they are plugged directly into the ES5000 jump starter unit itself. This normally sells for about thirty dollars at Auto Zone as well.

ES5000 Customer Reviews

I’ve had this jump starter for about a year and it has been used a lot. The unit is small and light weight making it easy to use. I’ve used it on several different vehicles and have had no problems. It’s nice not to have to ask for help when your battery goes dead. You just need to be careful that you don’t overcharge the battery in the unit or it will ruin it. I’ve been able to start my vehicle with this unit without a problem even if the temperature is below 30 degrees F. It takes a while but it does work. Highly recommend this product.

I purchased this because I was tired of having to go get another vehicle every time my battery was dead. I used it twice now on my pick up truck, once on my wifes car and once on a 4 wheeler battery and all worked like a charm! This thing works!!! I bought this product based on review’s and I’ll tell you what..this thing works great!! It has saved me multiple times in the past two years! If you are looking for a good quality booster pack with some decent power, then buy this one! You won’t regret it. This item did not work at all. The green light came on, but when tried to start car nothing happened. The lights flickered as if something was happening but the engine didn’t even turn over.

So called customer service (Booster Pac) they said the unit had to be charged for 24 hours and then try again. Did that and got same result except the lights were dimmer. Called them back and they said there was nothing they could do because it was out of warranty by 3 months (even though unit only had been used twice in that time). This is obviously a flaw in design or manufacture as other reviews for this product describe same problem as mine.

Is it easy to use?

I have been using my ES5000 for a few weeks now. The first thing I noticed was the quality of the unit. It is very well made with some of the most solid jumpers I have ever owned. This unit came with a nice storage case that is strong and durable, unlike other cases that are made of plastic and crack on impact easily. The case also has a pocket for all the accessories that come with the ES5000, like the light bulb and charger.

The ES5000 is set up to be very easy to use. There are no switches or buttons to push to charge it up or turn it on, just plug it in and let it charge up automatically. Once charged, you can use the 12 volt power port on the back of the unit to power any 12 volt device you need, such as air compressors, tire inflators etc.. There are 3 built in lights on this unit. On the side there is a red light that glows when charging and turns green when fully charged and ready for use. In front there are 2 more lights; one is used as a work light and one as a flashing emergency light for roadside emergencies.

I tested this unit out by charging it up fully then disconnecting from power source, letting it situnused for 3 weeks. Upon reconnecting it to my car battery (which was completely dead) it started right up without any issues. This unit is advertised as being able to jump start up to 15 times before having to be recharged. I would need several months of testing and dozens of jump starts before I could verify this claim but so far I have been very impressed with its performance. One thing that was very important for me about an external battery pack was its overall size and weight.

What could be improved?

This is a good jump starter but it could be great if they had not added the 12v outlet. I have used it several times without issue until I went to use it this past weekend and found it was not working. I had a cheap car charger plugged into the 12v adapter to charge my cell phone while driving. When I went to jump my car, I found the unit had no charge. It was a very frustrating situation.

I contacted ES5000 and they said that using any device other than their supplied jumper cable would void the warranty (even though the 12v outlet was designed for accessory power) and that it would cost me $35 to ship it back for inspection. I believe the problem with this unit is that there is only one charging port that can power both the battery charger and the 12v outlet at the same time. If you are charging your cell phone from the 12v outlet, you are also charging your battery at 1/2 speed. If you have it plugged in overnight, you may never get a full charge on your battery. If they offered a separate charging port for just charging the battery, this issue would be resolved.


The Booster PAC 1000 is a lightweight jump starter and booster pack. It is designed for the person who needs to start their vehicle fast and doesn’t want to hassle with jumper cables. It is a 12 volt unit that has an LED display, charger, and battery status indicator.

The Booster Pac 1000 can be recharged using the included AC adapter or through the DC charging port in your vehicle. The Booster Pac ES5000 can start vehicles up to 6L in size if they have a 12-volt battery system. The ES5000 has a peak current of 1000 Amps, which should be enough power to turn over any engine on the road today that has a battery voltage below 12 volts. However, if you have an older car with a 6-volt electrical system then this product will not work without some modifications to your vehicle’s electrical system! The packaging is clear and simple to understand.

The box contains:

  1. A Booster Pac 1000
  2. AC Adapter (120V)
  3. DC charging cord (for use in vehicles)
  4. Instruction Manual
  5. Safety Instructions sheet
  6. Warranty information sheet
  7. Product Registration card.


Our best recommendation for the average consumer that needs a starter is the Booster PAC 1000 Peak Amps 12v Jump Starter . This unit offers plenty of power to start most cars and trucks, but it does not come with the additional features and upgrades seen on other models. This makes it a great choice for consumers that need a unit that can get the job done without all of the fluff included in some of the higher priced models.
