Jesverty SPS-50II Bench Power Supply

The Jesverty SPS-50II is a compact AC-to-DC bench supply listing a 13.8 V fixed output or adjustable voltage and multiple output connections. Its power rating details conflict, so buyers needing a specific continuous current should confirm the exact rating before purchase.

At a glance

  • Voltage can be adjusted, with a fixed 13.8 V setting also stated.
  • Screw-type main terminals are accompanied by auxiliary snap-in terminals and a cigarette lighter socket.
  • Twin analog meters are listed for monitoring voltage and current.
  • A built-in fan and short-circuit protection with automatic current limiting are claimed.

Pros and cons

Pros

  • Multiple listed output connection options suit setups that use different DC connections.
  • The front-panel analog meters provide at-a-glance voltage and current readings.
  • Adjustable voltage offers more flexibility than a fixed-output-only supply.

Cons

  • The built-in fan means the unit uses active cooling rather than passive cooling.

What to know before buying

Listing details to confirm

Listing details are contradictory or inconsistent: output current is given as 40A continuous and 50A peak in one specification, but 50 A elsewhere. Voltage ranges are listed as 5-15V and 9V to 15V, while power is listed as both 50 watts and 690 watts. Dimensions and weight also differ between the details and A+ specifications. Confirm the rating, adjustment range and physical measurements for the selected listing before relying on them. The cigarette lighter plug is separately described as 10A max.

Who is it for?

A good fit for

  • Ham or amateur-radio setups needing a bench supply with a stated 13.8 V option and more than one output connection.
  • Hobby or lab users who want adjustable voltage and analog voltage/current meters.

Less suited to

  • Buyers who need a clearly confirmed continuous-current or power rating without checking the listing.
  • Users who need a supply specified for output voltages outside the stated adjustment ranges.

Customer feedback highlights low-noise operation, perceived clean power output, meter accuracy, versatility and value. The listing also reports mixed reliability experiences, including some customers saying units failed after limited use. Those perceptions may matter for radio or bench setups that depend on stable operation, but they do not resolve the listing's conflicting continuous-current and power specifications.

Positive themes

  • Customers praise the perceived low noise and power output.
  • Customers appreciate the meters, versatility and value.

Mixed feedback

  • Reliability feedback is mixed, with some customers reporting dependable operation and others reporting failures after limited use.

Frequently asked questions

Is the SPS-50II adjustable?

Yes. The listing describes a fixed 13.8 V option and adjustment, but gives two different ranges: 5-15V and 9V to 15V. Confirm the range for the listing you are buying.

Can it continuously supply 50 A?

That is not clear from the supplied specifications. One section says 40A continuous and 50A peak, while other details list 50 A without that distinction.

What output connections are described?

The listing describes screw-type main terminals, two pairs of auxiliary snap-in terminals and a front-panel cigarette lighter socket. The socket is separately described as 10A max.

Does it show voltage and current?

The product description lists twin analog V/A meters for real-time monitoring.
