Quick answer
If your outlet isn’t giving enough power, first check for a tripped GFCI outlet or circuit breaker. Test the outlet with a different device to confirm the issue. If the problem persists, inspect for loose wires or a faulty outlet.
Confirm the symptom
- Electronics plugged into the outlet aren't working properly
- Devices take longer to charge or run slower than usual
- The outlet works intermittently or only for some devices
- Other outlets on the same circuit behave the same way

Prep & safety
- Turn off the power to the outlet at the circuit breaker before inspecting or working on it.
- Ensure all devices are unplugged from the outlet before beginning troubleshooting.
Step-by-step troubleshooting
- Check for Tripped GFCIDo: Look for a GFCI outlet nearby (often in kitchens, bathrooms, garages). Press the 'Test' button, then press the 'Reset' button.Observe: The outlet powers devices normally after resetting.Means: A tripped GFCI was the issue.Next: Monitor the outlet for recurring trips.
- Test with Another DeviceDo: Plug a different working device into the outlet to see if it operates normally.Observe: The new device also doesn't work properly.Means: The outlet is likely faulty.Next: Check the circuit breaker.
- Check Circuit BreakerDo: Open the electrical panel and locate the breaker for the affected outlet. Ensure it's in the 'On' position.Observe: The breaker is tripped or damaged.Means: A tripped or faulty breaker is causing the issue.Next: Reset the breaker or replace it if damaged.
- Inspect for Loose WiresDo: With the power off, remove the outlet cover and check the wiring connections. Tighten any loose wires.Observe: Wires are loose or show signs of burning.Means: Loose or damaged wiring is causing poor power delivery.Next: Replace the outlet if wiring is damaged.
- Test Outlet VoltageDo: Use a multimeter to measure the voltage at the outlet. It should read around 120 volts.Observe: Voltage is significantly lower than 120 volts.Means: There may be a wiring issue or an overloaded circuit.Next: Consult an electrician for further diagnosis.
- Replace the OutletDo: If the outlet is damaged or not functioning properly, replace it with a new one of the same type.Observe: The new outlet functions correctly.Means: The old outlet was faulty.Next: Restore power and test the outlet.
Common causes
| Cause | Likelihood | Difficulty | Part often needed |
|---|---|---|---|
| Tripped GFCI outlet GFCI outlets shut off power to protect against ground faults. | Common | Easy | None |
| Tripped or faulty circuit breaker Breakers trip to prevent overloads or short circuits. | Common | Easy | Circuit breaker |
| Loose or damaged wiring Poor connections can reduce power flow or cause intermittent issues. | Sometimes | Medium | Electrical outlet |
| Faulty outlet Internal damage can prevent proper power delivery. | Sometimes | Easy | Electrical outlet |
| Overloaded circuit Too many devices on one circuit can reduce available power. | Sometimes | Easy–Medium | None |
| Voltage drop due to long wire runs Long wires can cause a drop in voltage, especially with high-draw devices. | Rare | Hard | Thicker gauge wiring |
Parts you might need
When replacing parts, ensure compatibility with your home’s electrical system:
- Electrical outlet: match the type (standard, GFCI, AFCI) and amperage rating
- Circuit breaker: match the amperage and type (standard, GFCI, AFCI) to the panel
- Wire gauge: match the existing wiring thickness for proper connections

Label all disconnected wires before removal to ensure correct reinstallation.
When to call a professional
- The outlet continues to trip or fail after replacement
- Voltage readings are consistently below 110 volts
- You notice burning smells, sparks, or discolored outlets
- Multiple outlets on different circuits show the same issue
- You're unsure about working with electrical systems
FAQ
Can a bad outlet affect other devices in my home?
Yes, if the outlet is on a shared circuit, a fault can impact other connected devices.
How do I know if my outlet is GFCI or AFCI?
GFCI outlets have 'Test' and 'Reset' buttons, while AFCI outlets are labeled on the circuit breaker.
Is it safe to replace an electrical outlet myself?
Yes, if you follow proper safety steps and turn off power at the breaker.
Why does my outlet work intermittently?
Intermittent issues often indicate loose wiring or a failing outlet.
