Dometic Portable Jump Starter 900A

G'day Nadia,

This device is primarily designed as a Jumpstarter, to be able to give short bursts of super high current to get a car started.
If using to charge devices via the USB output, such as mobile phone or ipad, you'll have around 13Ah.
most mobile phone batteries these days are 4Ah, so you'll probably get 3 full charges on a phone from this device.
If you dont need the jump starter function, you'd be better off buying a standard 15-20,000mAh powerbank like the Biolite Charge 80 which will charge your phone 4-5 times.

G'day Aaron,

Great question! You'll have no trouble using the Dometic Jumpstarter with a motorcycle battery.

G'day Melissa,

I've touched base with Dometic on this one who has advised that its a just a universal laptop power connection.
The physical pin is 5mm in diammeter.

G'day Ellie,

Yes, it will jumpstart your Toyota RAV4 Hybrid, but it wont power your Caravan Mover.

G'day Graeme,

This is a Portable Jump Starter, not a portable power pack.
It is designed to be used to provide a short burst of high current to jump-start a flat car battery, or to provide a quick charge option for laptops or phones.
It is not designed to be used as a portable power pack to provide continuous power to run an appliance, it will not provide ongoing stable lower Amp output over a number of hours.
Its abit hard to give further information without knowing exactly what your fish finders power requirements are, but you'll be needing a different set up or power source than this sorry.

G'day Lucy,

No, the Dometic Portable Jump Starter 900A is only able to be charged from a 240V wall socket or a 12v source like your vehicle or a portable power pack.

G'day Adee,

The only information we've got from Dometic is that the unit comes with 8 different laptop connectors/charging adapters ( fits most laptop charging ports). They all appear to fit the pin-style laptop chargers (have a squizz at the image with the alligator clips and pins), so I don't think you'll be able to charge a Microsoft Surface or Macbook with this unit.

G'day Lee,

Yes, the Portable Jump Starter is supplied with a 12V car cigarette plug lead that could be plugged into the PLB40. It would take about 5 hours to charge via the PLB unit.

G'day Mac,

The Portable Jump Starter has been designed to jump-start 12V batteries, so I don't think it will be suitable to jump-start a 6V battery.

G'day Robert,

Yes, it should do the trick, it has been designed to work with Diesel engines up to 4L, and Petrol engines up to 6L.

G'day Russell,

Dometic doesn't specify how long the Lithium Battery will last charged up, however most Lithium Polymer batteries will need to be recharged every couple of months. Given that the unit needs to be at least 50% charged to jump start, we'd recommend checking the battery percentage at least once a month and topping up as needed.
