    Default Do these battery charger gadgets actually work?

    I saw these two gadgets advertised on the Internet.

    The first, from Adendorff, works with capacitors, and they claim a recharge time of 100seconds.

    The second is a modification of a 5V Powerbank.

    Anybody with experience with these or similar products?

    I have this one and it has started a dead boat battery, land cruiser battery and a few sedan/hatch batteries. Very compact device.

    Without a doubt these units work extremely well. I can, and do, often start a big V8 without even blinking an eyelid.

    Itís a case of sifting through the chaff and finding a decent quality unit.

    Ok 4e, as promised. Some factors that may or may not be important to you.

    The Romoss -

    - 12000mAh capacity, more importantly (44Wh)
    - designed for 200A - 400A starter crank current. (Peak)
    - has only 15V charge facility (via included cig lighter socket)
    - Has 2 USB outputs to charge cell phones etc. (1A and 2A)
    - Price R1498 as far as I can tell.

    The one I use -

    - 16500mAh capacity, more importantly (61Wh)
    - designed for 300A - 600A starter crank current. (Peak)
    - has a 15V charge facility (via included cig lighter socket or via included mains adapter)
    - has a USB Micro Charge input (that the Samsung connector) so you can charge it from ant USB charger, like cell phone chargers.,
    - has 2 USB outputs to charge cell phones etc. (1A and 2.4A)
    - also has an additional 12V 10A output
    - and an additional 19V 3.5A output, complete with a lead and adapter set to charge/run a laptop.
    - Price R2650 as far as I can tell.

    Now I am not boasting or posting mine is bigger than yours - just showing you what I chose, based on what is important to me.
    Two deal busters for me are the charge options and the starter currents.

    Use to jump a 5L multiple times without a issue.

    Keep one of these in every car. I actually used it to jump a excavator which had a bad 12v battery (they 24v, so boosted the bad battery in series with the good battery).

    Really impressive little gadget. Also has a 12v car female socket so you could possibly run a fridge. I have ran a small compressor of it to fill up a pool inflatable.

    Thanks for all the good posts!

    I am still amazed that such a small piece of kit carries such a punch.

    Nobody commented on the Adendorff unit which works on capacitor technology.
    Any thoughts on that?

    Talking of packing a punch.

    There is another amazing product on the market that propels the average family car or TDi bakkie for 50m @ 100km/h with only 5ml. Have you ever tried pushing a car even 5m.

    Itís called Diesel.

    I am testing one of them batteryless chargers and they are awesome. I once started a car with battery at 11.6 volts without anything else. You just hook up the jump starter. Let it charge for a while, takes about 2 minutes to fully charge the capacitors and then you start the car.
    Is awesome.
    I think it is much better than the battery models. I also have some of the battery models but if you keep that in a healthy car you tend to forget to charge it every 2 to 3 months.
    With the capacitor charger you can just leave it for ever and charge it when you need it.

    The problem is when you are alone somewhere between Nowhere and NÍrens, and your battery is flat - how do you charge the capacitors?

    I think it has a step-up gadget built inside. Like I said, the car I started was on 11.6 and it charged with capacitors to 14.3.
    I did not use another vehicle to charge the capacitors, I used the flat battery to charge the capacitors.

    I could not believe it but it actually worked great. This was on my Hilux with a 3.4 Prado V6 in.

    Thus I see this model as a better option for people like me who like to travel alone in remote areas.

    The model I am testing is a 600Amp from the same factory as Adendorff's but is a sample I imported for testing purposes.

    I hear you, but what happens (like it happened to me last week) when something completely drains the battery (dash lights won't even go on)?

    Yes then you have a problem.

    The one model I am testing has a built in 18650 Li battery for those events, but then you are back to the battery models' problem, if you do not keep that back-up battery charged you are still in trouble.

    Thanks.

    That brings me to the next question.
    Does it harm these battery type jump starters if you keep them on the charger indefinitely?

    (I suppose the same question holds for powerbanks).
