BPC - PowerCrank Battery Centre / K-Tech Electrical, Offgrid & 4x4
David comes to your caravan park — including weekends — to fix solar and battery faults others have already missed.
His technical strength in 12V solar and caravan electrical systems comes through repeatedly, including cases where he succeeded after other electricians had already attempted the job. Two reviews raise concerns worth noting: one describes a cancelled online order where a refund was refused in favour of store credit, and another alleges incorrect wiring that caused component damage and then describes difficulty getting a response. These are the only two negative accounts in 22 reviews, so they don't represent a pattern — but if you're ordering products online or having hands-on electrical work done, it's worth clarifying the complaints and warranty process upfront before committing. For travelling or off-grid customers who need someone to come to them quickly and actually understand their system, the feedback is consistently strong.

About BPC - PowerCrank Battery Centre / K-Tech Electrical, Offgrid & 4x4
David is the face of this operation — a mobile auto and off-grid electrician who specialises in 12V systems, solar charging setups, lithium battery upgrades, and caravan electrical fault-finding. What sets him apart from a standard residential electrician is his focus on travelling and off-grid customers: reviewers repeatedly describe him attending caravan parks, camping grounds, and roadside breakdowns rather than fixed premises. He's particularly praised for diagnosing solar systems that other auto electricians had already looked at and failed to fix, suggesting a deeper-than-average familiarity with charge controllers, battery management, and solar panel wiring on recreational vehicles. Beyond emergency mobile work, the business also stocks and ships products — one Adelaide customer received a 2000W inverter within 24 hours of ordering — so there's a retail and supply dimension alongside the hands-on work. A colleague named Brad is mentioned alongside David in at least one job, and the business also trades as BPC – PowerCrank Battery Centre, reflecting a battery-specialist background that predates the broader K-Tech electrical branding. With around 26 years of operation, this isn't a new setup, but the review base is still relatively small, so the picture is drawn from a limited window of customer feedback.
Best for: travellers with caravan solar or battery faults needing mobile on-site help, off-grid system upgrades to lithium, and urgent 12V electrical repairs in or around Mount Gambier.

Does David come to you, or do you need to visit the workshop?+
Based on multiple reviews, David regularly travels to customers rather than requiring them to come to him — reviewers describe him attending caravan parks, private campsites, and even properties 80km from Mount Gambier. He's also confirmed to work weekends and after hours for travellers in genuine need. That said, some customers did bring their vehicles to him when that was more practical. It's worth calling ahead to confirm what's possible for your specific location and situation.
What kinds of caravan and off-grid electrical problems does this business handle?+
Reviews mention a wide range of work: diagnosing solar panels not charging batteries, replacing faulty charge controllers, upgrading to lithium batteries, fixing 12V lighting and fuse issues, repairing awning damage, and sorting out trailer wiring. Several reviewers specifically note David succeeded where other auto electricians had already tried and failed — particularly on solar-to-battery charging faults. If your issue involves 12V, solar, or off-grid power on a caravan or camper, this appears to be his core focus.
Can this business ship parts and equipment, or is it only in-person service?+
The business has a retail side as well as hands-on work. One reviewer in Adelaide received a 2000W inverter within 24 hours of ordering online from Mount Gambier. The business stocks brands including K-Tech Lithium Prodigy batteries and ITechworld inverters. However, two separate customers reported issues with online orders — including a refund dispute — so if ordering remotely, confirm the returns and refund policy in writing before paying.
How do customers describe David's communication style on the job?+
Several reviewers specifically call out that David explains what he's doing as he works, using language accessible to people without technical backgrounds. One customer described understanding the whole job process despite being a novice. He's also described as friendly and easy-going across multiple reviews. Whether that translates to detailed written quotes beforehand isn't confirmed in the reviews, so asking for a written scope before work starts is a sensible step.
Is this business suited to urgent or emergency callouts?+
Emergency response is one of the most consistently praised aspects across the 22 reviews. Customers describe contacting David late at night or on weekends and getting a same-day or next-morning response. Specific examples include a late Friday call for a broken trailer hitch resolved by Saturday morning, and a Sunday morning visit to fix a blown fuse in a rooftop tent. If you're a traveller in the Mount Gambier region with an urgent 12V or caravan electrical problem, the evidence suggests reaching out directly — even outside business hours.
