Fly Link Tech BD20 5000A Car Battery Jump Starter Air Compressor

That Cigarette adapter It's correct. Most people only carry a phone charger that plugs in to the cars cigarette outlet But if the battery is dead and they need to make an emergency call. You can plug that adapter into your jump box and then stick your phone charger into that

Yeah that makes sense. I get it now. I just kept thinking in the direction that it was supposed to plug into a cigarette lighter to charge the power pack but that is not the case. I guess it could be handy to have for some people but it seems like old technology. I don't know of anybody who still even has a cigarette lighter in their vehicle, at least in the traditional spot right up front underneath the radio area. My old Dodge has one but that thing is 24 years old! Strange thing is it has a cigarette lighter but no ashtray? I never did figure that one out. Anyway, thanks for the info.

The cigarette lighter adapter is a 12V (actually closer to 14+V, or whatever the jumper output is at the time) connector, for use as a power brick for 12V devices (which aren't terribly in vogue these days, with USB power more common). My question for you is how long can the air pump last, so will it pump up a fully deflated tire?

[@walleyspark]

Good question. I guess I kind of overlooked reviewing the air pump portion of this unit. I may do a follow-up video in the future. I only used the air pump feature once to top off the tires on one of my vehicles. They were all about 4 or 5 lb low. It worked just fine with minimal battery drain so I'm confident it could easily fill a 30 to 40 lb tire and probably more. Beware though that I did run across at least one review that claimed that their unit overheated after a few minutes and they had to let it cool down before continuing. Even so, in a jam I would say this would be real handy to have with you. Hope that helps to kind of answer your question.

[@richardefriend]

Thanks. I was just curious. I just bought the 6000A version (without pump), at a great price from Amazon of only $70. I also have a separate pump in the trunk that won't overheat and runs off the battery, since the odds of having a flat AND dead battery at the same time is pretty remote. I've also got an 18V Ryobi pump and a Dewalt unit that has a pump, AC power and 12V power, but it's soooo heavy.@@walleyspark

No real mystery about that female EC5 cigarette lighter socket cable that you thought might have been supplied by mistake. I use one with my car jump starter to power my inflatable kayak and paddleboard portable electric pump because those pumps all have a power cable that plugs into either a car's 12v DC power socket or using that connector, can be powered by a portable car jump starter instead. That is why many car jump starters come with that cable supplied now as it still has it's uses. It means I can inflate my kayak or paddleboard right next to the water's launch spot without having to do it where the car is parked which could be some distance away.

Yeah it took a while but I'm kind of understanding this now. At first I thought it was supposed to somehow charge the unit from the car battery via the cigarette lighter or jump start the car through the cigarette lighter. But that was wrong and now it makes total sense to me. The problem is I have absolutely nothing that plugs into a cigarette lighter and I haven't for years so I was confused. The last thing that I owned that plugged into a cigarette lighter for power was a portable vacuum but seeing that cars no longer come equipped with cigarette lighter ports I have no use for any of that stuff anymore. It's surprising to know that even something like a pump for your kayak would even have that type of adapter to power it because I'm guessing your car has no female cigarette lighter port. So without carrying along something like this unit you would have no way to power your pump. It seems like old technology to me. Most everything now plugs into a USB port. I'll hang on to this adapter but I don't see any use for it in the foreseeable future. At least not in my case anyway. Thanks for the info.

@@walleyspark It might seem antiquated but neither mine or my wife's cars are recent Ford models so they don't have bluetooth or USB connections. They do both have a built-in 12v power sockets though. I have also connected my car battery up to this car jump starter with the jump leads plugged in first and it has never sparked. I believe the clever circuitry means it is safe to do it that way.

To be fair, if it actually charges at or near 2.4amps which would be 12 watts or so it would technically be Fast Charging. If you normally do reviews for products that have some type of USB aspect, you may want to buy a Decent USB Tester (Not a super cheap one) so you can see what they charge at.

[@adegreen2731]

Do you notice a whinging noise coming from the unit when turned on? Wonder if it’s normal or a loose coil or something wrong with mine.

[@walleyspark]

Can't say as I did. The only thing I noticed was that clicking noise once I hooked it up to the truck battery. I'll double check for a whining noise the next chance I get. If I don't post anything back here in the next couple of days then I didn't hear it.

[@jmackinjersey1]

You should not use a fast charger on this. The heat could damage the battery and render it inoperable, or more likely it will shorten the lifespan and ability to hold a charge a long time. Use a lower powered, slow charger.

[@walleyspark]

Thanks for the input. I can't say that I agree with you 100%. Keep in mind though that I am not an electrical engineer. These are my personal opinions only from my personal experiences. I have never had a problem using a fast charger on any device. They either work and charge the device faster or they work and charge the device at normal speed or they don't charge the device at all. It all depends on what the device itself is capable of. In other words, some devices are made to accept a fast charger and some are not but the ones that are not it shouldn't hurt to hook a fast charger up to them, it'll just charge at normal speed. Just make sure that the fast charger is quality and also what's overlooked a lot is the cord. People buy these nice quality fast chargers and then use a cheap cord which defeats the purpose. And a cheap cord can cause problems in itself. I actually bought a second one of these jump packs. I used the correct recommended charger, 5v 2.4a, and it did the same thing. It charged to 99% and stopped. Once I unplugged it and plugged it right back in it was at 100%. So I don't believe my fast charger had anything to do with that original issue. I have since contacted the company to inquire about this glitch but have not received a response yet. In my opinion and for the price I paid for this it seems like they should have just thrown in the correct charging adapter in the first place! With all of that said I could still be wrong and you could be correct. My statements are based on personal experiences and knowledge only. 🙂 If you would like to add to this and show me some type of proof to your comment I would be happy to investigate further. I take no offense whatsoever to be proven wrong. 😉

I cant imagine 500a going through those little cables nevermind 5k.amps
