    Do these things work as advertised? We are considering buying a car in the UK but, the car would sit in an off-site storage garage for approximately 6 months annually. The garage has no electricity available so no opportunity for a batt tender. Being able to walk over to the garage - about a mile - with lightweight "insurance" that the car will start would be mighty handy!

    For years I have stored my 328 (and motorcycles) for 3-6 months at a time by disconnecting the battery. I do not like using chargers that are unattended, even if electricity is available. I would do the same with the UK car but want the ability to easily start it IF the battery self-discharged to the point where the starter would not operate.

    FWIW, my 328 has, until the last attempt, always started right up after reconnecting the batt. A few months ago it failed to start when I tried to move it out of storage so I had to remove the batt, take it home, charge it, take it back. For the first time, the jump starter would have been useful for the 328! TBF, the battery was 5-6 years old so not all that surprising...though annoying!

    SO...anyone have any experience with the Li jump starters? Any particular type/model?

    I have one. It works fine for starting as a booster if the battery is weak. Don't know if it would work if the battery is completely dead.

    My mother in law bought me a Halo Bolt years ago. I was highly dubious as most of those devices are usually dead when I need to use them. I charged it up, put it back in the case, and threw it on the work bench and expected to never use it again. About a year later I needed a jump on something, as the car battery was completely dead. I tried the Halo and to my surprise it fired the car right up. I have since used it many times and have never had it be dead when I needed it. I even used it for a lengthy start on an outboard where it turned the motor over ~20 times or so. Ive been VERY impressed with this battery.

    Image Unavailable, Please Login I used this one in the shop constantly for the past 2 years. Unless the battery is DEAD (say, less than 7-8V) it will start the car.

    I have a Top Vision brand jump starter. These new jump starters are great. I can start my old diesel farm tractor in sub freezing weather, something the regular battery has a very hard time doing even when fully charged. Spins it over like it's a 75* day. It can do at least a dozen starts before it needs to be recharged. Lots of test videos on YouTube.

    I have an Amazon equivalent of the Tack above. Mine even has the compass - that changes 45 degrees when the box is on. It is impressive what a little box can do. Yes, this will probably jump start the car from dead or nearly dead even if the jumper hasn't been charged in many months.

    I have the Imazing charger/jump starter. This holds a charge for a long time (months) and still starts a car. I've used it on my BMW 840Ci which has two batteries and requires a strong jump to start. This works every time. I have also used it to charge my phone and other chargeable equipment.

    This is the one I have. No issues. And has come in handy when someone is looking for jumper cables.

    Yesterday we purchased a 2019 Mini Cooper and will be keeping it in the space/method I referred to in post #1. I watched other videos of the specific application (sub 2-litre car engines) and a Noco GP20 started a larger engine than the Mini's 1.5 litre, 3cyl engine with no trouble. I figured a bit more power wasn't a bad thing - so I ordered a Noco GP40. Thanks again for the input/video!!

    It's amazing to me how battery technology has progressed recently - the idea that something you can easily hold in one hand could provide sufficient power to start a car engine is mind-blowing. A bit more advancement and they'll have e-cars/motos with sufficient range for me to buy them!! ;)

    BTW - This one comes with a cigarette lighter attachment and I used the battery and the attachment to run my 12v car vacuum. I ran it for about 30 minutes all together and it only dropped down to 77%.

    I once had to start my 328 4 or 5 times over maybe a 2 hour period with one of the small battery packs. It was amazing and now resides in my car full time. I put a reminder on my calendar every 3 months to charge the charger. It seldom needs it.

    Yep, same accessories. I really like the digital meter versus a good light/bad light situation.

    i just purchased a noco gb-40 to shock my porsche boxster back to life should the occassion arise.

    the porsche's present battery is 4-yrs. old and i know it's time is approaching. however, from what
    i read on the ACM-type batteries is that their avg. life expectancy is better than 4-5yrs. therefore
    i've decided to replace the 718 battery this fall during lay-up season.

    at any rate, i purchased the noco as a jump-start device and nothing more.

    folks i've talked to tell me they are a good insurance policy even for a stone dead battery jump.

    The Imazing jump starter looks identical to my Top Vision, just a different name on the case. Even the accessories and carrying pouch is identical.

    I also have an Imazing. Never had to use it on my own 308GT4 which I store with the battery isolated though I did have to use a much larger conventional external battery to jump start in France a few years ago in a heat wave when the battery decided it had enough though subsequent tests showed it was fine and I am still using it 3 years later.

    However I did use my Imazing a few weeks ago at a show to start a 348 with a flat battery and it worked perfectly.
