Electric Fence Energizer Brand Comparison
Speedrite vs. Gallagher vs. Cyclops vs. Patriot vs. Zareba — head-to-head on output, power sources, warranty, country of origin, and what each brand is actually best at. We carry four of the five and give an honest read on the fifth. Updated June 2026.
The 30-second summary
| Brand | Origin | Joule ceiling | AC / DC / Solar | Stand-out feature | Best for |
|---|---|---|---|---|---|
| Speedrite | New Zealand (Tru-Test) | 86 J | All three + multi-power | Cyclic Wave™ + remote/Wi-Fi on premium models | Large operations needing premium features |
| Gallagher | New Zealand | ~63 J | All three + lithium solar | iSeries fence monitor + smart-fence integration | Tech-forward operations; remote monitoring |
| Cyclops | United States (Texas) | 32 J | AC + DC primary | Strongest lightning protection on the market + Made in USA | Lightning-prone areas; institutional / NRCS buyers |
| Patriot | New Zealand (Tru-Test) | 20 J | All three (entry-level) | Lowest cost-per-joule in the entry tier | Budget-conscious portable systems |
| Zareba | United States | ~10 J (consumer) | AC + DC + Solar (small) | Wide retail availability (Tractor Supply, Lowe's) | Homestead / hobby — not commercial rotational grazing |
What this comparison covers (and what it doesn't)
Honest framing up front: Powerflex carries Speedrite, Gallagher, Cyclops, and Patriot. We don't carry Zareba, but we include it here because it dominates the consumer/retail tier of the market and ranchers ask about it. The Zareba section reflects our objective read of the product line, not a sales pitch.
Joule output, power source, and warranty data is verified from current manufacturer technical bulletins as of June 2026. Pricing changes regularly — figures here are directional; check the live PDP for current.
Brand-by-brand
New Zealand Speedrite
Owner: Tru-Test Group (subsidiary of Datamars). Built in New Zealand, the largest electric-fence-energizer manufacturer in the world.
Lineup: 0.4 J entry-level through 86 J industrial mains units. Premium models (6000i, 12000i, 18000i, 46000W, 86000W) use Cyclic Wave™ technology — a pulse shape that maximizes energy delivery down the fence line.
What they do best:
- Premium feature set on the i-series: remote control, Wi-Fi connectivity, LCD with output/battery/earth voltage, day/night sensor, half-voltage terminal, earth monitoring, battery saver tech.
- Multi-power flexibility — same chassis runs on mains, 12V battery, or solar.
- Joule ceiling — the 86000W tops the market at 86 J output for the largest commercial operations.
Trade-offs: Higher purchase price than US-built alternatives at equivalent joule output. Some premium models feel over-engineered for a simple cattle perimeter. Service network in rural US areas is thinner than Cyclops.
Best for: Mid-to-large operations that value the smart features + multi-power chassis. Default recommendation when budget allows.

New Zealand Gallagher
Owner: Gallagher Group, headquartered in Hamilton, New Zealand. Family-owned, founded 1938.
Lineup: Full range from sub-1J solar units through 63 J commercial mains. Strongest in mid-range solar and lithium-solar (S-series).
What they do best:
- Smart fence ecosystem — the iSeries fence monitor lets you check fence voltage from your phone.
- Lithium solar — the S120, S200, S400 lithium-solar lineup outperforms lead-acid solar on cold weather and runtime.
- Multi-power MBS platform — same energizer runs on mains, battery, or solar.
- Build quality — consistently rated for durability in independent reviews.
Trade-offs: No 80+ J giant in the lineup. Smart fence features add cost vs. plain energizers.
Best for: Operations that want remote monitoring, off-grid lithium solar, or the Gallagher brand's reputation for ruggedness.

USA Cyclops
Owner: Cyclops Electric Fence Chargers, manufactured in Texas, USA. Independent, US-owned.
Lineup: CHAMP (5 J), BRUTE (8 J), SUPER (12 J), MASTER (20 J), BOSS (32 J) on the AC side, plus DC battery variants of most models.
What they do best:
- Lightning protection — strongest built-in surge suppression of any brand we carry.
- Made in USA — the only US-made energizer in our lineup. Matters for NRCS / EQIP and BABA compliance.
- Customer service — 24-hour repair turnaround is the published standard.
- Honest pricing — the BOSS 32 J AC costs less than mid-range Speedrite or Gallagher at similar output.
Trade-offs: Joule ceiling of 32 J. No smart-fence app or remote control on most models.
Best for: Lightning-prone regions. Institutional and NRCS-funded projects requiring US-made compliance.
New Zealand Patriot
Owner: Tru-Test Group (same parent as Speedrite). Patriot is positioned as the budget-friendly entry-level brand.
Lineup: Entry-level AC, DC, and solar from sub-1 J to about 20 J. Simpler feature sets than Speedrite.
What they do best:
- Lowest cost-per-joule in the entry tier — typically 30–40% less than the equivalent Speedrite.
- Reliable build — same parent company as Speedrite means similar manufacturing quality.
- Simple operation — no LCD, no app, fewer failure points.
Trade-offs: No premium features. No giant-joule commercial models.
Best for: Budget portable systems, homesteads, small operations where simple-and-reliable beats featured-and-expensive.
USA Consumer tier Zareba
Owner: Woodstream Corporation (US-owned). The dominant brand in farm-supply retail (Tractor Supply, Rural King, Lowe's).
Lineup: 1–9 mile rated charger units ranging from ~0.1 J to ~10 J.
What they do best:
- Retail availability — available at Tractor Supply / Lowe's today.
- Made in USA on most models.
- Price point — the entry units are cheap.
- Consumer simplicity — spec sheets in "miles of fence" instead of joules.
Trade-offs: Consumer-grade build, minimal lightning protection, low joule ceiling. Not built for commercial rotational grazing.
Best for: Hobby farms, single-paddock pet/garden electric fence, very small operations. Not the right fit for working rotational grazing.
We don't carry Zareba and don't recommend it for commercial operations.

Brand FAQ
Are NZ-made energizers better than US-made?
Not categorically. Speedrite and Gallagher set the global premium standard for features and output range. Cyclops sets the US standard for lightning protection and warranty service.
Why doesn't Powerflex sell Zareba?
Zareba is engineered for the retail/hobby market. The build quality and joule output don't match what working rotational graziers need. We'd rather sell you a Patriot at the right price than a Zareba that you'll outgrow.
What's the difference between Speedrite and Patriot? They're both from Tru-Test.
Same parent company, different positioning. Speedrite gets the premium feature set (Cyclic Wave, remote, multi-power, large joule ceiling). Patriot is the budget-friendly line — simpler features, lower cost-per-joule.
I'm in a high-lightning area. What's the actual difference in lightning protection?
Cyclops energizers carry the highest built-in surge suppression in the industry. Regardless of brand, install a dedicated lightning diverter on your lead-out wire — see our grounding technical reference.
How do I size the energizer once I pick a brand?
Use our free electric fence charger sizing calculator — 5 questions, output recommendation across all power-source options.
The honest meta-point
The right brand matters less than the right grounding, right joule sizing, and right conductor. If you can't pick between two brands at similar output and feature set, pick the one you can get serviced fastest in your area.
