Spanarci has put a lot of focus on this unit to be extremely user friendly and versatile and it shows in practice. The safety features built into the unit make it such that in any situation, both the unit itself and your vehicle are protected from damage. The unit has a bright colorful LCD display that shows the unit function and battery life. This display does a good job communicating the status of the unit without the need for a troubleshooting guide like other units that use flashing lights and beeps to communicate status. After spending some time with the unit, it is evident that the company has packed a lot of features and functionality into this jump starter to make it very intuitive to use. This is also the first jump starter I've used that has a smart boost system. Given the thought put into the development of this unit, the ease of use of this product is above all others that I have used so far. I see myself gifting one of these to my grandparents as well, given the great usability that the Zeta 2000 has, I have confidence that they would have no trouble understanding how to use it.FeaturesThe smart boost feature makes this unit incredibly easy to use. All you have to do is connect the jumper cables to the battery, and the car is ready to start. In the case the voltage is too low to use this feature (the start text will light up yellow -I have included a picture of this-, or in extreme low voltage cases not at all), all you have to do is hold down the power and flashlight button to enter boost override mode. This will allow the unit to bypass the battery detection function to start a car with a very dead battery. This has proven very useful to me, as one of my jump starters that I have from another brand will not function at all in this situation with a very dead battery, only giving a beep / flash to indicate an error. As far as errors go on the Zeta 2000, this unit does a good job of having safety features to protect both the car and the unit from damage. It protects from overcharge / discharge (lithium batteries can be difficult if they are run completely dry of power), overcurrent/ short circuit, overheating and reverse polarity. All of these features work together to make this unit incredibly user friendly and safe to use. What is even better about these safety features, is the way that the unit tells the user the error it is encountering so it can be easily addressed. It is so annoying with my units from other brands that will just beep or flash without any indication of what is going on, and one has to go find the user manual to try to understand the error. This is not the case on the Zeta 2000.Other FunctionalityThe Zeta 2000 increases its utility with the ability to provide more functions than just starting a car. Having 12,000mAh of power, this unit makes a great battery bank as well. The included USB ports make it so that you can either charge any USB-A/USB-C device (phones, cameras, drones etc.). To illuminate the work area, the unit comes with a powerful 300 lumen flashlight with a nice flood pattern. This wide pattern makes the light very useful at night, and it also proved useful for me during a recent power outage to see around the house. We tend to lose our power quite frequently, so the second the power goes out the whole family goes looking for these jump starters to power their devices. So, this jump starter makes a great item to have in a vehicle emergency kit, around the house, or in a travel kit for camping.

I purchased this Spanarci Jump starter and one other more expensive one from a local store. I put them to the test. I purposely left the headlights on my 05 Toyota Sienna on a 20 degree day. The head lights went out and the car made no attempt to start. Not even a click.I first tried the other Jump starter, it did turn the motor over, but only for a few seconds but no go. So back it goes.I left the lights on again until the lights were out and no response from the starter.So now it was the Spanarci's turn.I hooked it up and the indicators turned right on. However the start indicator was yellow which indicates that my cars battery voltage was very low.So now for the special feature that I really wanted to test.Hold down both buttons until the percentage of charge indicator comes on, it will start decreasing as it dumps everything its got into the car battery. By the time I got back into the car to start it the Spanarci was down to 75%. The Van (V6 engine) started right up. Excellent.That wasn't enough of a test for me. So I repeated the test without charging up the Spanarci. I again drained the car battery until the lights were out and the car made no attempt to start.Hooked up the Spanarci, the indicators turned on and showed me I only had 70% left.Again the start indicator was yellow telling me the car battery voltage was too low. so I used the special boost function again. Held both buttons until Charge percentage started counting down again. This time it got down to 60% before I got back in to start the van. It started right up again.I now gave it one more test. This time the cars battery was only partially discharged. The headlights still would come on but the starter would click but not turn over.I hooked up the Spanarci for the third time. Indicators came on this time with a green start indicator.So without using the special function I turned the ignition key and the van started right up.I think I gave it a pretty thorough test. It passed all three on a single charge.Great performance that out did the more expensive model that I compared it to. So its a great value.I purchased 2 more so I can have one for each of my cars.

I was hesitant to buy this because I was not familiar with this brand. THAT DOESN'T MATTER!!! This is by far the best bang for your buck!!!! Our friend has a Schumacher one that he paid more for. His doesn't start a stone dead battery. This one does!!!! It is so easy to use. I've been very surprised at how long the charge lasts. The built in light is a great feature too. And not every situation can you get another car close enough to use jumper cables. We hate dragging out the big plug in battery charger... this eliminates all of that! My husband has used it more times than I can count just since Christmas. I like that we can also use it as a backup power source for our go-pro (or anything that needs charging) not all of our rides have cigarette lighter chargers.Anyone with an old car, hot rod, garage, golf cart, or lawn mower should buy this. I did my research and hands down for the price paid, this was the best unit available. FYI: We later ordered a case that was a little large for the unit, but luckily I saved the foam piece that came in the original box, so it has a little extra protection.

Works pretty well after modifications. I thought this was garbage, then I looked closer and realized that nothing but plastic was touching the terminals on any side post battery. Had to cut off a large amount of plastic to make clamps useable. Now the deice works fine. I'll update if anything changes.

I purchased the jump starter to have as an emergency back up since I own three cars.  I did not expect to use it so soon.  Two days after receiving, it was cold and my car wouldn't start.  I got the jumper and it showed 84 percent.  I had not charged it to 100% as I did not expect to use it so soon.  I  followed the very easy instructions and it immediately jumped my car.  I was able to drive to the store and purchase a new battery.  It has a boost feature which is for use when the voltage is too low.  I did not have to use this option but I am glad it is available.The LED flashlight is powerful and bright.  The digital screen is simple to read.  The user manual has large print and is straight forward.  The instructions say the jumper will hold a charge for up to two years which is impressive.  I am elated with this jumper which can also be used to charge my phone.  It has a rugged design and is waterproof. I was sold on the 2 year warranty. I wish it came in a case.
