Question
Can I use this to jumpstart a 6v car ?
I have a 1954 Ford Popular, with 6v electrics. Although it has a good (new) battery, after sitting during the winter, it is difficult to start. Can I use the Dynamic Starter to bost the battery to aid initial start up ? Please not that the car is 6 volt, not 12.
Thanks, Bob.

We do not recommend using a 12v jump starter on a 6v car as it may damage the car's electrics.

Question
Dynamic Jumpstart has not worked?
I charged it for 24 hours - however the red light did not come on - does this mean the internal battery was not charging.? When I followed the instructions and used it on my vehicle's battery there was no response at all. How do I know if the jumpstart was properly charged? I know nothing about engines but from reading the reviews thought that this would do the job - one comment said they had not used a far larger vehicle than I have for 6 months and it worked first time - I have a tiny daewoo matiz.

If the red light did not come on then it was not charging or was already fully charged. That or there is a problem with either the product or the AC adaptor.

The charger does have a gauge on the front of it, pressing the red button will tell you if it is charged.

The red light should be on while charging. Please check that the charging lead is connected properly. If the red light still does not come on while charging, please seek assistance at your local Halfords store.

Yes it does, although it won't charge as fully as through the AC adaptor.

It also has a cigarette lighter socket so you can use it to run 12V appliances from it.

You cant use a 9v adapter you need to buy a 12v one. Any universal power adapter that goes up to 12v DC will work

Do not use a 9 volt charger.This incorrect charger may have damaged the battery. The charger supplied with this product has a 12 volt output.

Question
Can the dynamic jump starter be used straight from the box and how many jump-starts can you get out of it in-between charging?
My Ford Galaxys is parked outside and the car battery dies a lot during the colder winter months. Even after I get it push or jump started in the morning the battery is often dead again when I come out of work. Depending where I am parked this can be a nightmare. How many times can the jump starter be used in-between charges?

Hi, thanks for your interest in Dynamic Jump Starter. The rating of the battery is 17 Ah battery fitted. This will supply approx 200 cold cranking amps of starting power to boost your existing battery to start the car.

The A/C charger supplied is a trickle charger but leaving on permanently is a waste. The unit needs to be fully charged after each use and every 3 months if not used.

You cannot jump start your car via the cigarette connector as the fuse for the socket and your vehicle internal wiring behind the dash is not suitable for jump starting. The battery leads must be used.

Have you read the instructions?

Needs 12 hours to charge initially and you need to press the red button to see how much charge there is. Works better charged from the mains

Please try this with the engine running, as no charger will be sent until the ignition is put on, If you find that this still has no effect, please return the product to your local store where the Parts team can assist you with this issue.
