Harbor Freight 4-in-1 Battery Pack Review

[@arciefan]

Appreciate your review and believe you that it says wait 5 minutes. But I highly doubt that is necessary , especially on that small generator. I may be wrong , but have never seen a jump starter make you wait that long. Thanks for the review!

[@HomesteadDIY]

Thanks. You're probably right. For a car battery that's dead it may require that amount of time, but hey! Better safe than sorry! Cheers!

[@williamcampbell4950]

I got that same one and when I turn on the compressor it starts to smoke

[@HomesteadDIY]

lol I hate when that happens. I still use this on a regular basis, both the compressor and the battery pack. Maybe I was lucky

[@OKBAOK]

I just bought mine today 08/25/2023 and bought the two yrs warranty to play safe. I initially charge in the wall outlet random lights came in from red yellow green then after two minutes stayed at green lights which mean to me is fully charged. It says in the manual initially charge it for 48 hrs🤔. Anyway there’s a low sound while charging, humming sound and like a morse code on and off. Just for your info. For now will see the performance. Have a good to all of you who reads this👋🙂

[@philipcoleman3381]

Lol, the closed caption says (applause) when it starts! Nice review!

[@HomesteadDIY]

Everyone should have applause when they begin a project. lol Thanks for watching.

[@TheChewy78]

I notice when you had it hooked up to the generator battery that all 3 battery level lights flash in sequence when the switch was turned on.. On the older models they only did that when just charging the jump starter itself vs being hooked and boosting up to your generator battery

[@HomesteadDIY]

Now you made me go look at the owners manual! While it does reference the running lights during charging, the manual is silent on when it's hooked up to a battery to charge it. So I don't know if that's a feature or a bug, but the battery pack has worked flawlessly each and every time I've used it, whether it's for jumpstarting a car or inflating tires. Thanks for watching. Cheers!

[@lailabug23]

What if you lost the power cord can i charge it with something else?

[@halibut1249]

the one they have now is less peak amps for about same price.

[@Bryan6640]

Can you connect this pack to a wall outlet and then trickle charge a car battery?

[@HomesteadDIY]

I haven't tried that, but I seem to have a recollection of reading somewhere that is NOT possible.

[@seanjackson1402]

Did you get a beeping sound while charging? I'm charging right now and there is a loud beeping sound and there is nothing in the manual that says it does that.

[@HomesteadDIY]

I did not. However, I just did a quick Google search and someone who bought a different model on Amazon had a similar problem. It was supposedly due to the unit being in the "on" mode during the charge. Not sure if that's your issue, but maybe it's something simple like that. Cheers.

[@tongvang724]

Can you use it to do stand alone battery charge?

[@HomesteadDIY]

I don't believe so. It's not a trickle charge battery charger, but rather a jumpstarter to give your battery a boost when trying to turn over an engine.

[@kblu65]

Mine has a USB port …I thought I could charge my iPad!!! So, what is the USB port for?

[@johnhouli3450]

Thanks it looks good what year is this system

[@HomesteadDIY]

I bought it about 2 years ago. I don't know if Harbor Freight updated the units or not, but it still works great for me.

[@OKBAOK]

@@HomesteadDIYI just bought that today and bought the two yrs warranty too

[@HomesteadDIY]

@@OKBAOK Probably not a bad idea on the warranty. They tend to be low cost and give you peace of mind if something should go wrong

[@aldodelgado5477]

Mine is not charging anymore and I only used it for no more than 4 months. Lights keep going from red to green and never stops at green anymore. It worked a couple of times. I never thought it would go bad so fast. Can not get a refund anymore since it’s only guaranteed for 90 days. I recommend buying a protection plan.

[@HomesteadDIY]

That sucks. I just used mine the other day and it's still operating fine. Charged it up too without issue. I'm not sure if it matters or not, but I check mine every month (the instructions recommend doing so) and charge it if it's low. Sorry to hear that, and a protection plan might not be bad on something like this. Harbor Freight is really good with their policies. I had a multitool that kept dying on me and I had the protection plan, and they kept giving me a new one. I ended up getting 3 new ones(!). The last one was an upgraded model and it's worked fine since. Again, sucks about your battery pack.

[@ignacioromero5014]

To be clear it does not charge in 30 mins. Mine fully depleted took over 12 hours

[@HomesteadDIY]

Yeah, if I gave that impression it was my mistake. As I noted in the video, it had appeared fully charged before I began to shoot so I hooked it back up to charge again and it took 30 minutes. However, I also check my battery pack monthly to see if it needs charging and if so, top it off. Might ultimately lead to battery failure down the road, but I also don't want it to be dead when I need it. Cheers!

[@elcompamartinez2647]

Can you charge it using the cigaret lighter ??

[@HomesteadDIY]

I guess if u had a lighter adapter that you could plug it into you could, but out of the box you can’t

[@823Labs]

you can trickle charge at low amps but never try to jump a car via the cigarette lighter... those wires aren't rated to handle that and you could cause a fire or other issues

[@HollywoodHaunter]

If you say it's good, I can trust you. Otherwise, we will haunt ya 😂 Great randomly finding you here. Hope all is well.

[@HomesteadDIY]

Ha! You're not allowed to view this. This is my super-secret stuff. But with that said, I do still use the battery pack. It still works well. Cheers!

[@rickym8515]

Thanks for sharing most likely going to buy this soon

[@HomesteadDIY]

A couple of months in and it's holding up and performing quite well. It is a quick and simple power pack that even my stepdaughter, who is not mechanically inclined in the slightest, was able to use without issue. And the air pump quickly fills vehicle tires too, which was a real help when I installed the tire pressure monitoring system I showed in a subsequent video. This has been a great all-around power pack so far and easily worth the money.

[@malakalghaithi6079]

Thank u, you are very helpful I really appreciate it!!!!!!

[@HomesteadDIY]

You're welcome!

[@dixieamerican1051]

don't try air up a truck tire mine starting melting after it got 20 lbs air in 10 mins

[@AurelienCarnoy]

Very nice

[@HomesteadDIY]

Thanks!

[@thomas.maryland6902]

Pump is not good, after 80 days my pump damaged. Nylon wheel inside is damaged. Now I am looking for spare parts.

[@HomesteadDIY]

Thanks, I'll keep an eye on that, but so far my unit is working just as good as the day I bought it, and it's gotten a lot of use in that time. Cheers!

[@raveninavaniam9438]

I just bought the 750 peak amp....I turned my van into a camper van and hope its safe to keep in the van with me.....does anyone notice an slight gassy odor coming from the thing??

[@ahora9663]

Read the instructions, I don't think it's for indoor use.

[@raveninavaniam9438]

@@ahora9663 that's what I was worried about.....but one of my friends tossed box and instructions away :/ ....so I contacted the Store and they proclaimed, " of COURSE it's safe, if you don't have it with you then how do you expect to have it with you if you need it ! " ....I was talked down to like an idiot. I have had to use it to jump start someone on the side of the road....where WOULD I safely store it ? ...hmmm....yes, makes me nervous having it inside van. I keep it by the door for a fast removal.

[@ahora9663]

@@raveninavaniam9438 Ill find my instructions someday soon haha. I used my power pack for the 1st time today

[@corinerayford]

Hey it’s not for indoor use. Are he manual states the power pack produces fumes so it should only be used in a well ventilated area

[@Evrenthewrencher]

Just got it looks like automatic charge and jump since it has limited bottons.if u did not buy 2 year replacement program,u ll be pissed at sometime of ur life

[@ericflores5748]

Got 3 within 3 days and compressor gave up after pumping 20 psi

[@HomesteadDIY]

Weird. I still use mine regularly

[@robertmaimone8733]

Looking fora lighter jumpstarter 4 my daughter, u might try that gizmo again, i guess u get what you pay for!

[@HomesteadDIY]

So far this has been handy. My stepdaughter used it for a good month until she finally got a new battery...which is what the issue turned out to be with her car. She's also a tiny thing and had no problem carrying it or using it. Maybe long term it will be a problem, but so far I continue to give it a Siskel and Ebert two thumbs up!

[@elcompamartinez2647]

I bet tirple AAA loves you!!!

[@kblu65]

In this particular situation why not just buy a new battery

[@HomesteadDIY]

Two reasons: first, to test this battery pack, and second, I’m cheap (probably more the second than the first :) ).

[@hectorh.1341]

Don’t buy it! I paid $90 for that jump starter charged it up put it in my trunk and two weeks later I got it out to try and start someone’s car and that piece of junk didn’t hold the charge. Yesterday I tried using it to put air in my tire and same thing happened it doesn’t hold a charge. It’s like you have to charge it the day you’re going to use it. Junk!

[@HomesteadDIY]

That sucks! Mine has worked flawlessly since I got it, and I use it regularly, relatively speaking. I've used it to jumpstart cars and my generator, and had to often fill a car tire that had a slow leak until I stopped being lazy and repaired it.I check to see whether mine needs to be charged once a month and have found it holds a charge without being use for for over a month, and then takes just a short while to fully charge. I still highly recommend it based on my own experience, which I guess is the only thing we can do. Cheers.

[@traceywilliams2160]

Mine work well until I push the plug in the back too hard and it broke. BUT I buy the warranties on harbor freight big items. Took it back, got a replacement and paid for the warranty only. QUESTION: can this unit charge a battery if it’s plugged in?

[@traceywilliams2160]

Can this unit charged a battery if it’s plugged in?

[@HomesteadDIY]

@@traceywilliams2160 Unfortunately, no. They're designed only for a quick boost, not charging.

That ground hook to a piece of metal have to do with the battery blowing up hook it to the battery ain’t gonna do nothing been doing it for years no problems. PS it’s so they don’t have a lawsuit.

[@HomesteadDIY]

You're right! Since posting the video when jump starting my generator, I just hook both cables up to the battery terminal. No issues and it starts right up. Still going strong!

[@Walter-ts1vu]

My name is only 750 and mine starts right away.

Cen Tech 3 in 1 Power Pack,,,, My Charger Died So I guess I have to Buy another Charging Cord or Give it away for Free

[@HomesteadDIY]

See? You needed to get the 4-in-1! But eventually all things go. I had a Schumacher battery charger that last just 4 years. My 4-in-1 power pack, though, is still going strong however.

[@Joez86]

Gotta connect the positive (red) cable first and then the black cable. Once started, THEN turn “off” the power before you remove the cables (in reverse order (black THEN red)). And never put both cable clamps in one hand when they can touch each-other (especially with the power STILL on). 🤦🏻‍♂️

[@HomesteadDIY]

You’re absolutely correct! Thanks!
