DO NOT BUY A OHME EV CHARGER UNTIL YOU HAVE WATCHED THIS (OR INSTALL ONE)

Product reviewed

• OMI Home Pro EV charger (criticized) vs.
• Installation of Simpson & Partners EV charger (recommended replacement)

---

Key points mentioned (unique)

1) Fault failure mode / repairability

• The OMI Home Pro is marketed/treated as a sealed, non-maintainable unit.
• When it fails, the reviewer says it effectively becomes “dead” and must be replaced (they removed it after it stopped working).

2) Warranty / support experience (OMI)

• After the failure, the customer contacted OMI.
• The reviewer characterizes OMI’s response as essentially “between the customer and their installer,” implying poor support during troubleshooting/rectification.

3) Install quality issues with the OMI job

• The reviewer describes the electrical standard as “pretty poor”, even if it “ticks a box.”
• Issues found:
  • Poor internal cabling/materials and messy workmanship
  • EV supply cable described as not even “high-tough”: called “proper crap” rubber 3-core
  • Cat 5 described as jammed/poorly routed and visually tacky
  • Use of mastic and sloppy brickwork finishing (drilled/blown out then covered)
• The reviewer reports no signs of moisture, so the failure seemed electrical/internal: “nothing coming out of this unit anymore.”

4) Connector / cable specification concerns

• The OMI install used WGO connections, and the reviewer claims the instructions likely advise not to use them.
• The reviewer warns that “EV Ultra” branding can be misleading unless it’s the named manufacturer (Doncaster Cables EV Ultra).
• Claims cheaper alternatives may quote standards but are unregulated/uncertain in quality.

5) Design / upgrade inconvenience

• Because the OMI unit is sealed and the cable run is limited, replacement may require:
  • Reusing a junction box (described as untidy), or
  • Installing new cable (which the reviewer is doing).

6) Charger-side differences highlighted during replacement

Simpson & Partners

• The reviewer calls it much easier to install:
  • Front cover off with two screws
  • Then additional/top section steps
• Different cable entries (e.g., bottom and rear) that allow drilling and gland mounting
• Uses lever terminals
• CT/CT connection provisions described as straightforward
• Key advantage: serviceable parts
  • Example given: if something like a PCP board fails, they can swap the part rather than replacing the whole charger

7) Maintenance philosophy comparison

• Reviewer’s claim: OMI is not truly “sealed/non-maintainable” (they found accessible areas under stickers).
• Even so, the business approach is argued to be replace-the-whole-unit, rather than parts replacement (as with Simpson & Partners).

8) Consumer unit (CU) comparison / electrical provisioning

Old CU

• RCD only
• Reviewer states there was no surge protection (and notes missing details such as glands/cable support)

New CU for Simpson & Partners

• Includes:
  • Main switch
  • Surge Protection Device
  • Spare ways, including a double pole bidirectional RCPO
  • Additional headroom for future circuits / possibly a secondary EV charger

Cable size change

• Existing meter tails: 10mm
• New meter tails: 25mm (extra capacity)

9) Network / load control (CT and Cat 5)

• Old install: Cat 5 alongside rubber flex cable
• New approach (reviewer’s description): EV Ultra has Cat 5 integrated, for a cleaner finish
• Reviewer explains CT clamp usage:
  • One pair for the CT
  • Remaining pairs can be used for hardwired Ethernet or solar/battery CTs

10) Waste disposal requirement

• Reviewer states the OMI charger should not go in the regular bin.
• It should be taken to a special electronics waste disposal point.
• Responsibility for disposal is described as unclear (installer vs customer), but the reviewer handles it.

11) Aesthetic / installation tidiness

• The reviewer contrasts the “cheap” look and routing choices (junction box/flex routing/mastic/Cat 5 tie-wraps) with a cleaner, more professional finish in the revised install.

12) Comparison to another product

• Simpson & Partners charger is said to look similar to Anderson Quartz.
• The reviewer notes their Anderson video exists for context, but they state the chargers differ (including cable entry options).

Pros / Cons (as stated in the video)

OMI Home Pro (Cons emphasized)

• Non-repairable in practice (failure means replacement, per reviewer)
• Poor internal build/materials found in this case
• Moisture wasn’t the issue, so failure appears internal/electrical
• Unhelpful support flow from OMI (blamed back on installer)
• More hassle later if replacement is needed due to sealed/cable run constraints
• Requires special electronics disposal (not a normal bin item)
• Reviewer alleges it is not truly sealed (accessible components behind cover/stickers), undermining “sealed unit” claims

Simpson & Partners (Pros emphasized)

• Parts are replaceable (e.g., PCP board), making repairs more feasible
• Easier install with accessible screws and flexible cable entry locations
• Cleaner cable routing with integrated Cat 5 EV Ultra cable
• Better electrical provisioning recommendation (surge protection + spare capacity)

---

User experience / install experience (what it felt like)

• Reviewer describes being called out for a charger that simply stopped working with no recoverable solution.
• After inspection, they dismantled the OMI charger and found it basic internally, disagreeing with the “sealed/non-maintainable” premise.
• They position Simpson & Partners as a straightforward swap/install, with improved serviceability.

Ratings / numerical scores

• No explicit numerical ratings (stars/scores) were provided.

---

Overall verdict / recommendation (concise)

• Do not buy the OMI Home Pro EV charger, based on the reviewer’s experience with failure/repairability, support issues, and poor installed build quality.
• Instead, spend more on a premium, serviceable charger like Simpson & Partners, ideally installed with a properly specced consumer unit (including surge protection and spare capacity) and quality EV cable.

Speaker-specific views

• Main installer/reviewer (dominant speaker):
  • Strongly argues against OMI due to failure/repairability, support process, and installed build quality
  • Recommends Simpson & Partners because of serviceable parts and easier installation
  • Provides detailed electrical comparisons (CU features, cable sizes, surge protection, RCPO/spares) and emphasizes installation-quality concerns
