Reviewing the TopVision Jump Starter & Power Pack.

THIS VIDEO IS NOT A RECOMMENDATION OF THIS PRODUCT. IT'S JUST INFORMATIONAL.

SECOND UPDATE: I removed the Amazon link because the battery is not longer available. I asked Amazon and the seller about it and they said the batteries were backordered because of Covid. But I wonder it it's really because of a large number of defective units. Several people have reported to me that their units did not work right. I have four of these and all of mine are working fine.

UPDATE: I posted a second review the TopVision, titled "Second TopVision Jumpbox Review" . It has worked great for us, but it DOES NOT have the amount of current potential they advertise. The cables are far too weak to supply the amount of current the company claims. And it will turn itself off after a few seconds at high load. But I confirmed that it will jump off a backhoe. See my second TopVision video for more details.

Update from a question posed by a viewer: This jump box will charge from any source of power, but will not charge as fast from weaker sources. I charge mine from a 3.5Amp charger that was made for cell phones and it charges from 20% to 100% in a couple of hours. In my Chevy Equinox it charged for 45 minutes and only gained about 15%. But in my GMC Sierra truck it charged from 20% to 85% over the course of a 90 minute drive. So the more amps the charger can supply, the faster it will charge.

I have now jumped off 5 vehicles on two charges and it performed excellent. The small display on the plug-in has a voltmeter built into it, which is very useful. It displays the battery voltage. There is no mention of that in the instruction manual.

This jump starter seems to do a good job. Since making this video, I've used it twice to jump off cars, charged several cell phones and powered an electric air compressor, and it has worked fine. The lithium batteries appear to hold a charge pretty good. Time will tell.

It got 4.7 stars out of 7056 ratings on Amazon, so apparently the crowd likes it. I paid $79.99 for it.

This is a battery starter and not a battery charger. I did a review of the Schumacher battery charger if you want to see one of those.

I know this is a few years old but, the button doesn't turn this unit on for jumping, it's on when you plug the cable cord in and that's when it starts timing down before shutting off. So I'd connect the cables to the battery first, then plug it into the jumper so you have more time to get into the car. The button is to turn on the accessories port power. And in case others don't know, this jumper doesn't charge up a dead battery, it's mostly supplying power to the starter motor so the engine can start and then the alternator can charge up the battery.

I have two little diesel tractors and they will never start when the weather is really cold and I need to plow snow. This jump pack makes getting them started much easier than getting my pickup close to the tractor and using jumper cables. It also charges cell phones and can be used for a flashlight. I bought one for my wife and each of my sons.

I used this thing to start a completely dead battery on a 2000 GMC Yukon. Just left it to idle for about 30 minutes and I was able to drive it around no problem. Will definitely be keeping this in my car from now on.

You suppose to hook up the cables first to battery, then plug up to the pack don't have to press the power button it automatically comes on when you plug the cables up

I have one. Started my neighbors car which had 0.0 vdc after leaving the headlights on overnight. 89% was the topvision power reading before using it.

[EndlessSims]

How do I charge the unit battery charger up to 100% on the unit itself? Think I found the usb c in to charge up the unit it, it’s charging up to be able to get the unit to 100%…It’s next to the DC out put on the side of the left side of the unit, charging fast too…was only 71% charged now at 73% lol it is charging up so can jump start my stuff especially my SUV

[meme-tghr]

Can I use this as a 12vdc source to power my kensun air compressor?

[juddrobinson]

I did watch this on also. I have a jump starter from harbor freight that has a usb port. I csn yse that to save batteries. Where i will use is my back 15 acres by my shop so i can use without sucking batteries!! Thanks, great stuff!

[sweetseawater]

I am about to place an order on Amazon! But I don’t know if it will run on my 2018 Subaru Forester ?

[LissaLynch]

Can you charge the unit IN the car? I'm thinking of getting this for my kids, but I want to see if it's possible to charge it using the 12V/lighter port in the car along with a regular wall outlet. Thanks!

[YouLookinAtMe-Bro]

If you hook the cables up before you plug them to the battery, that screen on the cables will show how many volts the battery has.

[johncrosley]

This G26 unit is rated at 21800mAh which sounds pretty good on the face of it. It can supply 5v and 12v from the same battery by stepping down the 12v to 5v for charging phones etc. Basic calculations using their figure of 76.96watt/hours gives the following. Just using the 5v o/p it has a capacity of 15400mAh. Using just the 12v this is reduced to 6400mAh. They get their figure of 21800mAh by adding the two together which is a total lie. It’s one or the other, not both. I don’t know how they justify this scam but obviously they are relying on most people not knowing enough to question their figures. What else are they lying about ?

[dairasanchez]

Por qué me mide el el voltaje del cargador su mismo equipo y emite una alarma y no pasa carga a la batería de la camioneta ? Me podrían ayudar muchas gracias

[BrianAwesome]

What does "188" mean, when its flashing that ?

[daveribbons]

Where did you buy this one. ?
I purchased one on Amazon. I think it's a bootleg.

[Odseus]

I bought this last year off of a flash sale on amazon. I couldn't get it to turn over with a 2018 subaru outback. It would just beep at me :\ It works fine on my mazda 6 tho.

[georgem.]

Amazing that batteries so small can source the current to start the car. Bet it makes quite a bang in a fire.

[bennygarcia]

Has anyone struggled to charge this? Mine just wont charge

[SaltiDawg]

Nope, Positive *first* . Negative *second* . Then connect to unit.''
Bought it two days ago at Amazon... $79.99 minus 20% minus another 10% for Total of *$59.35*
