Have you tested the adapter?

i dont have any electric testing stuff it does show a light on the powerpack to say its charging it, but it dosent want to last very long

Hi Gaz,

you should use a 12V 500mA as this is what the included charger supplies.

By the way out of two I bought one charger did not work. Got a free replacement.

Hi Gaz, to breath new life into the lead acid battery in these chargers use a optimate 4 charger and conditioner, I have and use them they are the business. Buy Battery Chargers - Lead Acid & Automotive OptiMate4 auto maintainer-charger UK TecMate TM-142 online from RS for next day delivery. They are able to bring them back from the dead when showing only 2volts I have brought batteries back that have shown 5 volts, never as low as 2 but seeing is believing, and I have seen it do it many times. They are great.

I still stand by my decision to go for 20Ah gel cell batteries and an electronic triple stage charger. They are now five years old and still going strong.

I think those "powerpacks" are a false economy.

We should have a poll to see how long the "average" powerpack lasts.....

Just my 0.02 euro

Just one anecdote of Wednesday one week ago.

My bike tyre had a puncture. After fixing it I thought it would be quicker to bring it up using the built in pump of the power pack.

After a few seconds the normal pump rattle sounded a bit strange and then full stop occured. I brought the unit in and used another one.

Coming back in again - strange smell, somehow electric. Clicking noises out of the power pack, which proved to be the smell source as well.

So I had to throw the unit out onto the grass, and after putting protective gear on I started dismantling the beast feeling like a bomb disposal guy !

When I got it out I noticed there must have been a fault in the chipboard, and luckily the battery was not shortened. But still frightening ...

For my EQ6 I bought a 75Ah leisure battery instead. Much better system, and also quite neat as I bought a weather proof box with it with a proper on/off switch and socket.

how do you go about regulating the power from one of the leasure batterys?

[Merlin66]

basically, you don't!

The mount, or whatever load you have just draws the current it needs...if it wants 1.987A that's what it pulls from the battery...

[garethmob]

ahhhhhh i see, the reason why i ask, i bought a sec of "rings" with a power port on the end from FLO and it said about unfused........ do you need a fuse anywhere

[Merlin66]

I've never use in-line fuses.....nothing has blown up ..yet.

ahh ok thanks merlin
