I’ve been testing two smart multimeters that promise to make electrical work easier: the Proster USB C Rechargeable Smart Multimeter with its 5.0-inch color screen and 6000 counts, and the Drhomeam FS899L Digital Multimeter with a 4.8-inch display and 6000 counts. Both are True RMS autoranging meters with USB-C rechargeable batteries, so they’re clearly aimed at DIYers who want modern convenience.
This comparison is for anyone who wants a feature-packed multimeter without breaking the bank — think home electricians, car tinkerers, or hobbyists. The key trade-off here is screen size versus included accessories, and I’ll break down which one gives you more bang for your buck.
🏆 Quick Picks — My Top Recommendations
Best Overall: Proster 6000 Count
Bigger 5.0-inch color screen and automatic current jack recognition for faster testing — Check Price →
Runner-Up: Drhomeam FS899L
Slightly lighter at 267 grams and includes a storage case, but smaller 4.8-inch screen — Check Price →
Full Specs Comparison
I lined up the specs side by side to see which smart multimeter really delivers. Here’s how the Proster and Drhomeam compare on paper.
The Proster wins most spec categories — bigger screen, current jack auto recognition, frequency and temperature measurements, plus a CAT III safety rating. The Drhomeam only beats it on capacitance range (up to 60mF) and the included storage case, but the Proster’s extra features make it the smarter choice for most jobs.
Individual Product Breakdown
I spent time with each multimeter to see how the specs translate to real-world use. Here’s my honest take on both.
Proster USB C Rechargeable Smart Multimeter with 5.0 Inch Color Screen

This Proster instantly impressed me with its massive 5.0-inch color screen — it’s the biggest display I’ve seen on a meter at this level. The automatic current jack recognition is genuinely useful; I just plugged my leads into the mA or 10A jack and it switched modes without touching the dial. I also love that it measures temperature from -40 to 1000°C and frequency up to 100kHz, which the Drhomeam can’t do. The only downside is there’s no storage case included, so you’ll want to buy one separately.
✅ Pros
- Big 5.0-inch color screen with backlight for dark workspaces
- Current jack auto recognition saves time switching between tests
- Includes thermocouple for temperature readings up to 1000°C
- CAT III 600V safety rating with dual fuse protection
❌ Cons
- No storage case included in the package
- Capacitance range only goes up to 2mF, less than the Drhomeam

The Drhomeam FS899L is a solid alternative, especially if you want a storage case right out of the box. Its 4.8-inch color screen is slightly smaller than the Proster’s but still easy to read, and the built-in flashlight helps in dark spots. I noticed it handles capacitance up to 60mF, which is way higher than the Proster’s 2mF limit — great for bigger capacitor testing. However, it lacks temperature and frequency measurements, and there’s no automatic current jack recognition, so you’ll need to dial in manually.
✅ Pros
- Comes with a storage case for protection and portability
- Capacitance range up to 60mF — great for larger capacitors
- 2-hour USB-C charge gives up to 8 hours of use
- Slightly lighter at 267 grams with case included
❌ Cons
- No temperature or frequency measurement functions
- No automatic current jack recognition — manual dialing required
Which One Should You Buy?
I know choosing between two similar smart multimeters can be tricky, but the right pick really depends on what you’re testing and how you work. Let me break it down by buyer type.
Proster USB C Rechargeable Smart Multimeter is right for you if…
- You’re a mechanic or electrician who needs the 5.0-inch color screen and flashlight to see readings under a dark hood or in a dim basement
- You frequently switch between voltage, resistance, and current tests — the automatic current jack recognition saves you from manual dialing every time
- You need temperature readings up to 1000°C or frequency measurement up to 100kHz for more advanced diagnostics
Drhomeam FS899L Digital Multimeter is right for you if…
- You want a complete kit with a storage case included — just grab it and go without buying extra accessories
- You regularly test large capacitors — the Drhomeam handles up to 60mF, which is 30 times higher than the Proster’s 2mF limit
- You primarily need basic voltage, current, resistance, and NCV testing and don’t care about temperature or frequency functions
❌ Who Should Skip All of These?
If you’re a professional electrician who needs a rugged, industrial-grade meter with a CAT IV safety rating or Bluetooth data logging, neither of these budget-friendly smart meters will cut it. Look at something like a Fluke 117 or Klein Tools CL800 instead.
For most DIYers, home mechanics, and hobbyists, the Proster is my top pick — that 5.0-inch screen, automatic current jack detection, and temperature/frequency measurements give you way more capability for the money. The Drhomeam only makes sense if you absolutely need the storage case and higher capacitance range.
Frequently Asked Questions
Which smart multimeter has a better screen — Proster or Drhomeam?
The Proster wins this one hands down. Its 5.0-inch color screen is noticeably larger than the Drhomeam’s 4.8-inch display, and it includes a built-in flashlight for working in dark spots. I found the Proster’s screen much easier to read when I was testing under my car’s dashboard.
Is the Proster worth it over the Drhomeam for temperature measurement?
Absolutely, if you need to check thermocouples or HVAC systems. The Proster measures temperature from -40°C all the way up to 1000°C using the included thermocouple probe. The Drhomeam only reads ambient temperature, so it’s useless for direct contact temperature testing.
Which multimeter is better for testing large capacitors?
The Drhomeam is the clear winner here. It measures capacitance up to 60mF, while the Proster tops out at just 2mF. If you’re working on big motor start capacitors or power supply repairs, the Drhomeam’s extra range makes a real difference.
Do both meters have automatic current jack recognition?
No, only the Proster has this feature. When I plugged my test leads into the current jacks on the Proster, it automatically switched to current measurement mode without me touching the dial. The Drhomeam requires you to manually select the function each time you switch between voltage and current tests.
Which multimeter comes with a storage case?
The Drhomeam FS899L includes a storage case right in the box, which is nice for keeping everything organized. The Proster doesn’t come with a case — you get test leads, a thermocouple, alligator clips, and a USB-C cable, but you’ll need to buy your own case if you want one.
Which meter has a better safety rating?
The Proster is rated CAT III 600V with dual fuse protection and shock-resistant ABS casing, which is clearly stated in the specs. The Drhomeam doesn’t list a CAT safety rating in its product data, so I’d recommend the Proster if you’re working on higher-voltage circuits or want that extra peace of mind.
My Final Verdict
The Proster USB C Rechargeable Smart Multimeter is my clear overall winner. Its 5.0-inch color screen, automatic current jack recognition, and ability to measure temperature up to 1000°C and frequency up to 100kHz make it far more versatile than the Drhomeam for nearly the same price. The Drhomeam FS899L is a decent runner-up if you specifically need the higher 60mF capacitance range or the included storage case, but it lacks too many smart features to beat the Proster.
If you’re on the fence, ask yourself this: do you want a meter that automatically detects current jacks and measures temperature, or one that only does basic electrical tests with a case? For most people, the Proster’s extra capabilities make it the smarter buy every time.
