The Adventure King's mark 1 DC-DC charger was so popular we could barely keep up with demand
because it offered such great value and so many high quality features now we've gone back to the
drawing board and made it even better with lithium charging capability there's a lot that goes into
a quality DC-DC charger so let's take an in-depth look at the Adventure King's Mark ii DC-DC charger
firstly these have been designed tested and engineered in Brisbane Australia we paired up with
intel equip solutions an engineering and r d firm with over 30 years experience plus they're keen
4WDrivers too who for the last two years have been building prototypes and testing them in the lab
and in the real world under extreme conditions and harsh environments all around Australia
that process has led to a unit that's right up there with the best in the business
Adventure King's DC-DC charges have been designed and developed to be super reliable and ready
for Australian conditions we've done that by using high quality industrial grade components
from brands like Panasonic Western instruments and Linear technologies industrial components
are an even higher grade than commercial which means they're able to run in hotter temperatures
that and the large heat sinks and smart design means that these chargers will continue to put
out their 20 or 25 amps respectively even when they're inside temperature is close to 90 degrees
celsius they have two internal temperature sensors and a third external temperature sensor that's
designed to fit right onto the terminal of your battery ensuring a highly accurate reading and
ideal connection with over temperature cut off and temperature compensated charging
your DC-DC charger will reduce charge current to the battery or cut it off completely if your
battery gets too hot well before the limits reached on the unit that way you're ensuring
your battery has a long and healthy life and there are plenty of other built-in protections as well
short circuit and reverse polarity protection battery temperature and charger over temperature
protection over and under voltage protection and over current protection and because it's a true
multi-stage variable charger it's even able to recover dead batteries if this unit can detect
5 volts in your second battery it'll attempt to recover it and charge it back up and if
you have the 25 amp unit with the built-in MPPT solar regulator it'll prioritise the solar input
so if you're getting 15 amps of solar input it'll only require a further 10 amps from the alternator
for the full 25 amps if you can supply it with 360 watts or 25 amps of solar it's able to utilise all
of it that'll take the load off your alternator while you're driving to save you fuel and ensure
that your battery is efficiently charged whether you're driving stopped or sitting at camp we've
included an ignition sense wire to make this unit work with all types of alternators including
eco or smart alternators it also makes the unit work much more effectively if you've got an
older vehicle that might suffer voltage drop or when it's fitted to a trailer or caravan and is
connected to a long wiring run plus by connecting one of these four wires you can select your
battery chemistry grey for lithium orange for AGM yellow for flooded lead acid and white for calcium
by choosing the right chemistry you'll get the most efficient and effective charge for
your battery every step of the way we've pushed the design development and testing
even the aluminium housing with its built-in heatsink and the addition of special thermal paste
meant this unit would run 10 degrees cooler and the engineers took this project head completely
modelling the charging profiles testing the unit in cycles between negative 40 and plus 60 degrees
ambient constantly using it in their own vehicles throughout the testing process and going on large
trips to gather as much real world feedback and data as they could the mark 1 DC-DC charger has
performed flawlessly on all our trips and the mark ii is already proving what an upgrade it is
this has been designed developed engineered even programmed and tested in Australia and we're
incredibly proud of the result these are a top quality and feature packed unit and whether you
choose the 20 amp model or the 25 amp model with built-in MPPT solar regulator you know you can
rely on it to efficiently and effectively charge your batteries wherever you are in Australia
