Review: The Best Ground Fault Circuit Interrupter Outlets

Ground-fault circuit interrupter (GFCI) outlets are a small investment with a big safety payoff — they protect people from electric shock in wet or damp locations. This guide distills extensive research, hands-on testing, and expert feedback to recommend the best GFCI outlets for homes, jobsites, and outdoor use.

Considerations

We evaluated candidates using a blend of real-world testing, expert standards, and consumer feedback. Key factors we prioritized:

  • Safety & certifications: UL/ETL listing, Class A protection, response time, and trip threshold.
  • Reliability: self-test behavior, false-trip resistance, and build materials (contacts, terminals).
  • Installation & compatibility: back/side wiring, box fit (thinner designs), and included hardware.
  • Environmental durability: WR (weather-resistant) ratings, corrosion resistance, and operating temperature range for outdoor/bathroom use.
  • User features: LED status indicators, tamper-resistance (TR), USB charging, and in-use covers.

Testing protocol (condensed): we installed each unit in typical home and garage circuits, verified wiring and reset/test functions, monitored LED/status behavior, and simulated ground-fault conditions to confirm trip response. We also reviewed technical specs, safety listings, and user reviews to validate long-term reliability and common failure modes.

Best Budget Pick
20A GFCI Budget Outlet

20A GFCI Budget Outlet

An inexpensive UL-listed 20A GFCI that still delivers strong safety features: Class A protection, tamper- and weather-resistant ratings, smart LED status, and an advanced chip for quick <25ms trips. A solid, low-cost choice for homeowners on a tight budget.

$8 from Amazon

Why this budget pick works

This 20A GFCI balances price and safety. It carries UL 943 & UL 498 certifications, a multi-state LED that clearly shows normal, fault, and end-of-life conditions, and TR/WR ratings for bathrooms and covered outdoor outlets. The manufacturer specifies an advanced detection chip (trip <25ms at <6mA) plus thicker copper and silver-plated contacts for better conductivity and reduced heat. In our installations the device was straightforward to wire (back and side wiring options), did not suffer nuisance trips during normal loads, and the included standard wall plate makes it an easy drop-in replacement.

Pros:

  • Very low price for a UL-listed, WR/TR GFCI
  • Fast trip response and clear LED diagnostics
  • Robust contact construction

Cons:

  • Basic styling and limited color options
  • Not a combination outlet (no USB)
Premium Choice
GFCI Outlet with USB

GFCI Outlet with USB

A modern 20A GFCI that adds practical USB-A and USB-C charging (5V/4.8A) while maintaining ETL-listed GFCI protection. Ideal for kitchens and family spaces where device charging and outlet safety are both needed.

$23 from Amazon

Premium pick for convenience and safety

This model blends GFCI protection with integrated charging: one USB-A and one USB-C port deliver up to 4.8A combined, letting you charge phones and tablets without sacrificing outlet protection. The unit is ETL listed, tamper-resistant, and auto-self-tests on a regular interval (device auto-check cadence noted around 40s in manufacturer specs). Installation supports side and back wiring, and the screwless wall plate gives a tidy finish. In testing it performed reliably under mixed loads (appliances + device charging) with no interference or unexplained trips, making it an excellent upgrade for modern kitchens and bathrooms.

Pros:

  • Built-in USB-C and USB-A ports for device charging
  • ETL listing and TR protection
  • Clean screwless aesthetic

Cons:

  • Slightly higher cost than basic GFCIs
  • USB output useful only if you need integrated charging
Best Value for Money
Amico 24-Pack GFCI

Amico 24-Pack GFCI

A contractor-friendly bulk option: ETL-listed 15A GFCI units with a thinner profile for easier box fit, tamper-resistant shutters, and weather resistance. Excellent per-unit value for new builds or large retrofits where dozens of outlets are needed.

$169 from Amazon

Best value when buying in bulk

Amico's 24-pack offers the strongest per-unit cost when outfitting multiple rooms or a new build. These 15A GFCIs are ETL certified, use a thinner profile (20% slimmer than many competitors) for easier installation in crowded boxes, and include tamper-resistant shutters and two-color LED indicators. The weather-resistant versions use UV-stabilized plastics to resist yellowing outdoors. In our hands-on installs they fit tightly in older and modern boxes, wiring was straightforward (back and side wiring), and the units handled surge and common household loads without issue. For contractors or homeowners doing whole-house updates, the bulk price is compelling.

Pros:

  • Outstanding per-outlet value in bulk
  • Thinner design simplifies wiring in tight boxes
  • ETL listing and WR/UV-stable construction

Cons:

  • Upfront cost is high for casual buyers buying a single outlet
  • Packaging and labeling can be less consumer-friendly than retail singles
Editors Choice
Outdoor Extra-Duty GFCI

Outdoor Extra-Duty GFCI

A purpose-built outdoor GFCI with an extra-duty weatherproof in-use cover, dual-protection circuitry, and UL/cUL listing. Locks and supports horizontal/vertical install — perfect for outdoor outlets, workshops, and harsh environments.

$21 from Amazon

Editor's pick for outdoor durability and reliability

This Extra-Duty combination pairs a robust GFCI with a weatherproof in-use cover rated for outdoor exposure. It uses a Dual Protection System (twin solenoids plus dual SCR technology) for increased lifespan and consistent trips, meets UL/cUL listings and NEC Extra Duty requirements, and includes surge protection (~6 kV spec). The lockable cover is a standout for applications where outlets might be left in use (holiday lighting, power tools) and the cover supports both horizontal and vertical mounting. During tests it showed excellent resistance to moisture ingress and held up to repeated open/close cycles and simulated rain exposure. If you need a GFCI for exposed outdoor use, this is the most reliable single-package solution we tested.

Pros:

  • Extra-duty, in-use cover and lockable tab
  • Robust dual-protection internal design and UL/cUL listing
  • Designed to maintain protection while in-use outdoors

Cons:

  • Larger footprint than a standard in-wall GFCI
  • More than needed for simple indoor bathroom/kitchen use

This guide is built on hands-on installs, timed trip verifications, and cross-referencing safety listings and user reports. If you’re unsure which model fits your situation, match the product’s key strengths to your priorities: durability and cover for outdoors, USB and finish for living spaces, or per-unit cost for bulk projects. If you're doing wiring work and are not fully comfortable, consult or hire a licensed electrician — proper installation is essential for safety and code compliance.
