Purchased recently to set up as a portable DCDC & Solar charger unit for a battery box & caravan solar blanket controller. Very compact & can be mounted on a flat base, plus Bluetooth monitoring was an important feature. There is no user profile & remember to enter the Ah of the Auxiliary battery under Settings (menu bars top left of screen) in the App.

Working for solar, but yet to recharge the battery box in the Ute with a DCDC start battery connection.

To connect the phone with Bluetooth to the charger using the Hardkorr App first connect an auxiliary battery & hold the green background POWER button down for 3 seconds until a battery type LED indicator blinks (Page 5).
Now the appropriate battery type can be selected (press to cycle through the options) AND the Bluetooth pairing mode is active.

Start the App, a white battery icon & ‘searching’ notice is seen, this will very quickly show a ‘Connect’ link to touch / select.
Exit the setup mode by a 3 second long press.

Excellent DC Charger, great quality, good instructions, well packed and It just works.
However, the App does not appear to want to work….don’t let that deter, this charger is solid!
Great over the phone Hard Korr personalized service was beaut as well!
