Title: Best buy I've made this year.
Review: Don't usually do these reviews, but I have bragged about this purchase to several friends so I thought I should give the public shoutout.This thing looks great, works great and is easy to use and understand. Literally have attached it, and immediately started my car. Feel like the price was really good and the value is off the charts!

Title: 1000% worth the money!
Review: If you’re on the fence about this product, buy it! Don’t wait any longer. It’s a bit bulky, but it is also just as powerful! Using it for jumping smaller cars to my 1994 suburban. It always gets the job done with no issues. I was super impressed when it jump started my RV. At first the rv wouldn’t stay running after the jumper turned off, so it was literally just running my RV on its own power! Then it really came through for me at work when one of the diesel street sweeepers broke down. It ended up just needing a jump and I ran to my car to grab this jump pack. Absolutely no hesitation jumped a street sweeper. And even more impressive, started my friends mack truck like it was a Honda civic! Thinking is a work horse with the added bound of a battery pack for your phone!

Title: Jump Starter, 4000A Car Battery Jump Starter with Wall Charger
Review: Pros:* I was able to use this fairly quickly and it worked great. It started my Hemi twice without recharging in between. It has already paid for itself.* The display is large.* Includes a wall-plug power supply for charging. I have not used it, but it is there.* The flashlight works. I am not sure how effective it is, but it is there.Cons:* It is large. But it probably needs to be.Hopefully it lasts a while.

Title: A strong and powerful device
Review: A strong and powerful device that is simple to use comes with a respectable bag with a handle. But I still haven't figured it out but turn on the flashlight. I would say that it is lacking.

Title: Seems good!
Review: I haven't used the product yet but it seems of good quality and easy to use. However the user manual is not good as it looks like it was written by a 5 years old boy who does not speak English well enough!Even Google Translate would do a better job translating Chinese to English! For this I removed 1 star from my rating.

Title: Broke the first time I tried to use it.
Review: Unit was only showing 88% charge when I received it. It took approximately 14 hours to achieve 100% charge The first time I tried to use it on my Ford F250 it would not start the truck and died after about three seconds now it will not take a charge. It’s too late to send it back so I’m stuck. I have four other units made by other companies. This is the first one I’ve ever owned that does not work

Title: It really works!
Review: Works as advertised. I have gone through many full sized lead acid jump packs and none worked as reliably as this little gem. I was very surprised. It effortlessly started the engine in my Toyota Tundra with a completely dead battery. It takes up very little room so I keep one in each of my cars just in case.

Title: This is a beefy jumpstarter!
Review: What’s included - Velcro case, USB-C charging cord and adapter, jumpstarter, jumpstart cables, instruction manual.Charging - Unit arrived about 85% charged, it is important to fully charge it before use (USB-type C). It charged up in about 45 min- 1 hr. The blue LED readout is nice & large, and easy to read.USB powerstation – Tried charging my phone, with the USB-A to USB-C cord (included). I was a bit confused, as it seemed that pressing any of the side buttons wakes up the unit, and displays the LED percent charge. But just because the display is on, does not mean that the unit was active. It did not charge my phone, until I pressed the side center power button (kind of looks like the letter G). Now, the “Out” light was displayed, and it charged my phone. FYI – There are two USB-A output jacks (one is the speedier blue “SS’), and one USB-C input. Also, there is the special jack for jumpstarting. There is a rubber cover over all the jacks, and they are nicely labeled.Jumpstarter – Have not needed to use this yet. It states that it is capable of jumpstarting up to a 10 liter engine (our little Honda is only 1.5L!). You need at least 30% charge to jumpstart. If you connect the jumper cables wrong, you will not get the ‘Ready’ light, and a red exclamation point appears on the display. For such a beefy unit, it is interesting that the instructions state that you need to wait 1 minute between multiple start attempts. It also discourages from more than 3 attempts to start.LED Flashlight – This light will not light up the sky, but has acceptable brightness. I like that it has 3 modes – flash light, strobe light, and red light strobe SOS.Weight – This thing weighs a good 2 lbs, but in the case with all the equipment, it weighs 3.5 lbs..Capacity: 4000A. They suggest topping it off every few months with a recharge. I sometimes take a jumpstarter with me when I travel, and on flights. Don’t quote me on this, but I believe that the TSA allows lithium power banks as carry –on (never in checked baggage), provided that it is less than 100 watt-hours. This unit’s specs say that it is 74wh, so theoretically it should be OK to take on a plane. However, in the manual (#1 under Reminders) it says that ‘it is prohibited on airplanes or ships.’Overall, seems like a solid unit so far.This is an objective and unbiased review, and as a trusted reviewer, I may receive products or services.
