8.8 / 10 · our score
An adjustable 0–30V, 0–10A switching bench supply with a 4-digit LED display, coarse and fine adjustment and a 5V USB port. It is the tool that lets you power a project with a current limit instead of hoping a battery or wall adapter does not cook it.

Our verdict
A current-limited bench supply is the most underrated tool on a hobby bench: set the voltage, set a sensible current limit, and a wiring mistake shows up as a current reading instead of a burnt component. The SPS-3010 does that simply and precisely. Its switching design is noisier than a linear supply, which matters only for sensitive audio or analogue work.
Pros & cons

- 4-digit display for precise voltage and current
- Coarse and fine adjustment knobs
- Handy 5V USB output
Cons
- Switching design has more output noise than a linear supply
- Potentiometer controls lack memory presets

Getting started with the Jesverty SPS-3010 30V 10A Bench Power Supply
Before connecting anything, set the voltage with the output open, then short the leads briefly and set the current limit — for a small kit, a few hundred milliamps is a sensible start. Connect the project and watch the current display: if it hits the limit immediately, there is a short or a reversed part. Raise the limit only when the circuit behaves.
Who it's for
Hobbyists who want to power and test projects safely with an adjustable current limit.

Jesverty SPS-3010 30V 10A Bench Power Supply: common questions
Why use a bench power supply instead of batteries?
A bench supply lets you set an exact voltage and, crucially, a current limit. A short circuit or reversed component then draws only the current you allowed, instead of whatever a battery can deliver, which protects both the project and you.
What current limit should I set for a soldering kit?
Start low — a few hundred milliamps for most small kits — and check the current reading when you power up. If the supply goes straight into current limit, look for a short or a reversed part before raising it.
Switching or linear bench supply?
Switching supplies are lighter, cheaper and more efficient; linear supplies have lower output noise. For digital projects, LED kits and charging, switching is fine. For sensitive audio or analogue work, a linear supply is quieter.
