Hi All,
Is anyone familiar with the Suaoki G7 unit? I purchased one June 8 this year, I charged it to 100% and stuck it under my Patrol seat. Vacuuming my car yesterday, thought I'd better check the charge level, the instructions say to top up to full charge every 3 months. So it was a week or so over 3 months, it was dead flat and it was definately turned off by the main slide switch when it was stored. Plugged it in overnight, all ok. So my point is, if the instructions say top it up every 3 months, it should have plenty of charge in it at say 10 or 11 weeks after charging! So has anyone left one longer that 3 months and still had a reasonable and servicable charge for an Emergency engine start? Thank you. Michael

If it is the 18000mah model then there is no way it can deliver 650 amps through the jum cable size. THe potential difference available also ensure that cannot happen.

The trouble with jump starters is they go flat because they are batteries too, so unless you have charged in just before the trouble you don't know you are going to have, they will probably not start anything.

Sort of convenient, prehaps but most only assist the start and cannot perform when they are discharged.

Almost daily charge check may see it do the job as intended. Having a dual battery system I have never considered one for the reason of them being unreliable or as you found, discharged when needed.

Thanks for you post but there a lot of guys with good results from this particular unit. Technology has moved on and a lot of the old theories have gone out the window. Regards, Michael.

Hi Peter I was thinking that may be the case, I'll watch it over the next few months and log the capacity drop. Regards,Michael

I have the G7 charger and after 5 months showed 95%

Started my diesel Prado the other evening when the main battery was dead flat and still showed 95%

Maybe keep a note of charge date and % for a while to see if it’s faulty.

Cheers

Logic has it that if the 95% reading after a stored period and then also 95% after a start, I would suspect the display isn't a true indication of its performance.

Hi RMD

Not sure how much it would change after a 2 second burst to start the car.

One day I might try disconnecting the main battery and just use the G7 to start a few times and see how it reads. (Yes they are 18000ma)

A handy device though to have in the car, I can charge phones iPads and it is a torch all for $99 with a bunch of different plugs for laptops etc.

NO WAY would I ever attempt to remove the main battery and try to use the little starter pack.
If you get a voltage spike from a connection during as it starts or running you probably will destroy some electronics in the vehicle, maybe the alt reg too.

A foolish thing to try if your life isn't depending on it. If your life is relying on it, then give it a go.

Ok thanks RMD for the warning. I will give that a miss then.

Just keep it tucked under the back seat and keep it charged.

Cheers

From what has been said above it seems you have a bum unit and thus you have a warranty claim. Charge it fully and check the charge level weekly. There is one report of 95% capacity after an extended time. If the charge level drops too quickly report the loss of charge to your supplier and arrange for a replacement.

Yes Peter, tried to communicate to the Chinese seller tonight, told him what happened , he sent me the instructions and the following reply to me was to keep it charged. Typical of Chinese sellers. It's 100 % charged now, I'll log it's static discharge and see how it goes. It's unused so I think its a dud. Thanks Peter. regards Michael

Hi Michael

When I purchased our unit new back in April, I gave it a full charge and it then just sat in the box.

Before we went away in August, I checked it out and it still showed 100%, but still topped it up to be on the safe side.

Sitting under the back seat when we were up in Nhulunbuy, the chap next to us had a flat battery one morning and asked if I had a set of jumper leads. I said yes, but have something better.

I then get out the G7 and as quick as a flash started the diesel Captiva. The chap could not believed how good a job the small unit did, and he took a picture of it on his phone and was going to buy one when he got back to Darwin. After I tested it after the start, it still showed 100%. According to the stats, they jump start a vehicle over 20 times before they need to be fully charged again.

I told him to look around, as I ended up getting mine for $80, a reduction of $9 and I was very happy with the price, including free delivery.



Cheers

Thanks Stephen, another good practical and positive endorsment. They seem to be a good backup for the money. It also saves hooking up your own vehicle and the worry of potential damage to electronics out in the middle of nowhere. Regards, Michael.

So true Michael and to think nearly 25 years ago and well before eBay, I paid $119.95 for top set of jumper leads ..........lol

They are always in the car but to be honest they have only ever been used a few times.

Stephen, True about the jumper leads, I made mine up 40 years ago with huge Utilux clamps, I still have then but they are heavy and bulky at 3 plus metres long. Also the G7 has the extra options, torch, USB charging for computer or phone and flashing lights may be handy for a busy road breakdown or accident. How things have changed. regards, Michael

Being Lithium, it shouldn't have any self discharge although its management electronics would drain a little bit over a long period.
If it keeps going flat then it likely has issues.
Totally flattening lithiums is generally instant death to the cells.
