The search term asks for an outlet current tester, but none of the listings in this set states that a plug-in outlet tester measures current. This page therefore covers four outlet testers and circuit analyzers, each described by its listing for wiring checks, GFCI or AFCI trip tests, and voltage readings. The figures are copied from the listings with the date each one was checked.

Outlet and breaker testing involves mains voltage. Confirm the stated voltage range and category rating before connecting anything, follow the manual, and leave any wiring fault to a licensed electrician.

Quick answer

Match the tester to the job. The NTTYIECX analyzer covers the widest list of functions, including AFCI, RCD and load tests. The focemta kit pairs a voltage pen with a GFCI indicator tester. The NOYAFA is the choice when locating the correct breaker is the goal, and the LSENLTY is a battery-powered outlet tester with a stated 30-volt minimum and a loop mode. Check each listing’s stated voltage window against your outlet.

NTTYIECX Circuit Analyzer NXCT01 Battery Powered Minimum 120 volts AC Wiring faults, AFCI, GFCI, RCD, load testing
focemta FTVT01 Non-Contact Voltage and Outlet Tester Battery Powered Pen 12-1000V AC; GFCI tester 90-135V AC Voltage pen with LED flashlight; GFCI indicator tester
NOYAFA NF-8401 Circuit Breaker Finder Battery Powered Minimum 90 volts AC; maximum 120 volts AC Breaker finder, GFCI outlet tester, NCV detection
LSENLTY 2-in-1 Outlet Tester Battery Powered Minimum 30 volts AC Polarity, LOOP impedance, GFCI, NCV

How the list was built

The four picks come from the extra product list for this topic, and each one is an outlet tester, a circuit analyzer, or a breaker finder that includes an outlet check. The keyword’s current-testing wording does not appear in any of these listings, so the title names the product type they share. Figures are limited to the listing fields and bullets, and the page does not verify them against the physical products.

Product picks and who each one fits

1. NTTYIECX Circuit Analyzer with GFCI AFCI Tester and Outlet Tester

Listing figures (checked 2026-10-18):

  • Power source: Battery Powered. Minimum operating voltage: 120 volts AC. Model: NXCT01. Item weight: 1.1 pounds.
  • Item dimensions: 2.5 x 0.98 x 6.3 inches. Color: black.
  • Bullets name five functions: wiring fault detection, AFCI testing, GFCI testing, RCD testing and load testing.
  • The outlet section lists six conditions: Correct Wiring, Open Ground, Open Neutral, Open Hot, Hot/Ground Reversed and Hot/Neutral Reversed, shown with red and green LEDs.
  • Load testing is listed at 12A, 15A and 20A, with a voltage drop percentage on the display.

Best for: buyers who want the widest set of stated functions in one handheld unit.

Check before buying: the bullets say it is for North American 120V AC three-wire outlets, so confirm that your circuit matches before relying on the load results.

2. focemta Non-Contact Voltage Tester and Outlet Tester with Display

Listing figures (checked 2026-10-18):

  • Power source: Battery Powered. Minimum operating voltage in the specs: 12 volts AC. Model: FTVT01.
  • Specification met: CE, CAT III 1000V and CAT IV 600V.
  • The pen covers 12-1000V and 48-1000V AC with non-contact detection, a color display and an LED flashlight.
  • The outlet tester works by direct insertion at 90-135V AC and shows indicator lights, with no screen.
  • Included items: one pen, one outlet tester, two AAA batteries and a manual.

Best for: buyers who want a voltage pen and a GFCI indicator tester in one kit.

Check before buying: the title says “Color Screen Display”, but the bullets place the color display on the pen and say the outlet tester needs no screen. Read the product page to see which item has the screen.

3. NOYAFA NF-8401 Circuit Breaker Finder with GFCI Outlet Tester

Listing figures (checked 2026-10-18):

  • Power source: Battery Powered. Operating range: minimum 90 volts AC and maximum 120 volts AC. Model: NF-8401.
  • Style: Portable. Color: orange. UPC: 762744788551.
  • Bullets describe a breaker finder for 90-120V AC circuits, with visual and audible alerts and adjustable receiver sensitivity.
  • Also listed: non-contact voltage detection, an LED flashlight, low battery indication, auto shut-off, adapters and an EVA case.
  • Conflict on the count: the number-of-items field says 5, but the included components field names one circuit breaker finder tool.

Best for: buyers whose main task is finding which breaker feeds a circuit.

Check before buying: the listing’s operating range stops at 120 volts AC, so confirm it covers your panel before buying.

4. LSENLTY 2-in-1 Outlet Tester with Non-Contact Voltage Detection

Listing figures (checked 2026-10-18):

  • Power source: Battery Powered. Minimum operating voltage: 30 volts AC. Upper temperature rating: 40 degrees C. Model: SK3001.
  • Item weight: 0.1 kg. Specification met: ETL. Warranty: 3 year.
  • Bullets describe a POLARITY mode for wiring faults, a LOOP mode for line-neutral loop impedance, and a GFCI function test.
  • The NCV mode has a sensing distance of less than 5 cm, and the display can hold a reading with a one-touch data hold.
  • Conflict on the box contents: the bullets say two AAA batteries are included, while the included components field lists only the outlet tester and manual.

Best for: buyers who want a low-voltage starting point and a loop check in a compact tool.

Check before buying: the listing does not state a measurement range for the loop mode.

Worked example: reading the voltage windows side by side

The NOYAFA lists an operating range of 90 to 120 volts AC, and the NTTYIECX lists a minimum of 120 volts AC. The two figures meet at 120 volts, so a circuit at that level sits at the top of the NOYAFA window and at the floor of the NTTYIECX rating. A buyer whose panel work runs above 120 volts should check both listings before choosing.

The LSENLTY lists a 30-volt minimum, which is well below either of the other two. The focemta outlet tester lists 90 to 135 volts AC, so its window sits higher than the LSENLTY window and overlaps the NOYAFA window between 90 and 120 volts.

Load testing is a separate number. The NTTYIECX bullets list 12A, 15A and 20A load settings, which are current ratings rather than voltage ratings. The other three listings state no load setting, so their figures cannot be compared with the NTTYIECX load results.

What the listings do not say

  • None of the four listings states a current measurement range for an outlet check.
  • The focemta title and bullets disagree about which part carries the color display.
  • The NOYAFA number-of-items figure of 5 does not match its single listed tool.
  • The LSENLTY loop mode has no stated measurement range, and its battery count conflicts between the bullets and the included components field.
  • No listing states a warranty length for the NTTYIECX or the NOYAFA.

Frequently asked questions

Can an outlet tester measure current?

None of the four listings states a current measurement for an outlet check. The NTTYIECX lists load testing at 12A, 15A and 20A, but that is a load test on the circuit, not a plug-in current reading.

Which listing has the lowest minimum operating voltage?

The LSENLTY lists 30 volts AC as its minimum. The NTTYIECX lists 120 volts AC, and the focemta specs list 12 volts AC for the kit.

Does the NOYAFA work on a 240-volt circuit?

The listing states an operating range of 90 to 120 volts AC and gives no figure above 120 volts. Treat any higher-voltage use as unconfirmed until the seller states it.

Which of these include a GFCI test?

The NTTYIECX, the focemta kit, the NOYAFA and the LSENLTY each list a GFCI function. The focemta describes its GFCI tester as direct insertion, not non-contact detection.

Do these testers include batteries?

The NTTYIECX lists batteries among its included components, and the focemta lists two AAA batteries. The LSENLTY bullets name two AAA batteries, but its included components field does not, so confirm the battery count on the product page.

Conclusion

These four listings differ in their stated voltage windows, functions and included parts. The NTTYIECX has the widest set of listed functions, the focemta kit adds a voltage pen, the NOYAFA is built around breaker location, and the LSENLTY has the lowest stated minimum. Choose on the figure your job depends on, and confirm any gap in a listing before you buy.
