Battery Starter for Car, TOPVISION 2200A Peak 21800mAh Portable Car Jump Starter (Up to 7.0L Gas or 6.5L Diesel Engine), 12V Portable Battery Booster

For those of you who may not know, if the 12V car battery is actually reading 12V on a test, it is considered "dead" (discharged). 12v is just a nominal designation.I tested my car battery and it read about 7.5V for a 350 CID / 5.7L gasoline engine. My Topvision has been in the wife's vehicle since the first of May, so 5 months later this unit was at 88% after an entire blistering Sonora High Desert heat summer (inside a rear interior compartment).Heat is a battery's true enemy. The cold - not so much short of Arctic conditions, at least for a good battery.My battery tested at apx 7.5 VDC. Naturally, it didn't start right away nor should anyone expect it to. The attempt was to gauge how this unit works.It would not start right after the unit was connected (didn't expect it to), but waiting several minutes, the vehicle started right up, while only taking 3% (down 88% to 85%) capacity of this unit.The manufacturer said that the unit turns itself off after 30 seconds, and to reattach the cables to reengage the charger. I just know it works (from other vehicles) that it has to sit there for more than 30 seconds, just a few minutes and even a recently failed 'dead' battery (that will not hold a charge) will jump start with this unit as I described: attach it, wait a few minutes, start your engines - at least in my experience. I'd remove and reattach the cables if I came across a particularly stubborn battery.I had the vehicle run for a good 15-20 minutes to charge the jumped battery with the alternator, though I understand that it is better to go out and drive it around for that purpose. This unit is a whole lot easier than using my trusty old Schumacher 1200 peak amps (with built-in light and compressor) lead acid battery jump starter.The old-school Schumacher unit served me well and for a long time (especially with how much I used it as an aux battery source for charging electronics) until the inevitable point where its battery could no longer hold a full charge.If this old unit was fully functional and all I had, I'd have had to stand there holding it in place under my Van's hood, or perch that heavy unit precariously atop cables and hose, guess whatever time it took to charge the battery sufficiently, then disconnect it, try to start it, and repeat as necessary given my Van's (any Van's) cramped engine compartment.The old school jump starter's placement under the hood in SUVs or most Coupes & Sedans was doable, but not in all cases. This could be very precarious and impractical in compacts too. This hand held unit could easily fit on top of the battery and makes it possible to close the hood from the rain.This unit may not have a tire compressor built into it, but it surely is FAR easier to find a place to securely set it where one doesn't have to worry about it shifting from its place or falling from the vibrations when starting the engine- especially true in my cramped Van engine compartment.This is especially nice if my wife ever had to use it, not that she could not handle the old bulky Schumacher but like that she would no longer need to lug that old heavy unit, especially during inclement weather, where it's light weight will not be pressing on hoses or pulling on any wires or vibrating out of its place.This unit also has a sufficient enough light built into it to see the battery to clamps proper polarity. Very important feature, and it can also be used as a power bank for electronics.Even with built in polarity protection, nobody wants to test that feature, especially when stranded. I'd advise making the polarity indicators as easy as it can be to tell the difference even in low light conditions.I used Yellow, Red and green oil based paint marker pen on fluid caps & fuse boxes because auto manufacturers love stamping indicators like this in black, including the battery terminal +/- markings.I also use those red and green battery terminal pads for their stated purpose and as an additional indicator of polarity, but those pads can get to the point where its hard to tell which color is which.

I really like this TopVision Battery Starter backup. Compared to the old battery starters, which weighed quite a bit more, and took up a lot of space, this compact device is the cat's meow..I have used it to start my MC and charge the battery through this device. I have also used it to help a neighbor start their car which needed a battery replacement.This device will fit in most glove boxes, under a seat, or in the back of the passenger cab of a truck.The length of time between charging this starter pack is phenomenal. Over a period of 6 months or more of non use, and stored in my truck, it only lost 30% of its charge. Charging time is good. I always check all my devices on a regular basis to make sure that everything is up to 100%.There is an LED Flashlight with Long Battery Life: The battery starter utilizes bright LED flashlight with 3 modes :Flash Light, Strobe Light, and SOS Light. When not in use, this car battery starter can hold power for about 24 months, always ready for help you.Add to the purchase a warranty against defects unknown (I never experienced one), and you have a really decent charger at a very affordable price.You can use it as a Portable Power Supply: With dual USB 3.0 5V/3A, 9V/2A, 15V/1.5A output, this car starter battery pack can be used as a power bank to charge smartphone, iPad, and other USB devices.Don't forget What U Will Get: Acmount P100 Jump Starter, Smart Jump Cables, USB Type-C Charging Cable, Storage Case, User Manual; 3-Year Warranty and Life time reliable Technical Support.

Love this battery starter, especially during the cold days when the battery dies because it is too cold outside. I have used it several times and the battery is still at a pretty decent charge and keeps going. I have also left it in the car and it has remained charged at a good charge.Four stars because I could not fit the charger into the case as well, of course it should stay inside the house but those things get misplaced so it is nice to keep it all in the case.

The battery in my car died while I was parked and this gadget started my car without any problem. This starter is much more reliable, much safer, and so simple to use that each of my vehicles have this. The biggest plus is that you don't need another car for a jump start!

I've been on the look-out for a small, portable jump starter for quite awhile.I was comparing different ones on Amazon and came across this Topvision G26 for a great price.I like to read customer reviews before I buy things. The G26 has over 2,300 reviews on it. 96% of them were 4 & 5 star reviews....79% were 5-star. Other similar jump starters had good reviews, but most only had several hundred reviews instead of thousands.I also turn to YouTube to watch videos of people actually using the product. I found one video of a guy named "Project Farm" who tested 8 different jump starters and the Topvision G26 came in a strong 2nd, but about $35 cheaper than the 1st place jump starter.I received my G26 today. It had 84% charge straight out of the box. I plugged into a USB adapter and charged it to a full 100% charge which took about an hour.I was anxious to try it out on my 1992 Chevy Silverado which has a bad battery that goes dead if I don't start and drive my truck every few days. Well, I haven't driven that truck in a week...so, the battery was completely dead.This evening, after my Topvision G26 was fully charged, I hooked it up to my Silverado's battery. I turned the ignition key and my truck started right up on the first try. The G26 shows 88% left after jumping my truck.The Topvision G26 comes in a nice hard case and stores easily behind my seat in my truck. I couldn't find the warranty terms mentioned anywhere on the Amazon listing, but now that I have the unit...the user manual say's the G26 is backed by a 24-month warranty.The Topvision G26 is a solid, little jump starter and will come in handy!
