The display is bright. The documentation is in Chinese but has been translated below. good bang for the buck. Details: the meter came boxed in a hard plastic case to protect it. See attached images so the packaging and instructions. the instructions are in Chinese but it is pretty easy to figure out. Accuracy I found it to be only 4.8mv off at 7.7000V which is 0.06234% error rate this exceeds its spec of +/- 0.3% the test was done with a 120000 count meter that is in calibration. current requirements.

And it has already failed. Was using it to monitor a 12v power supply with the meter powered from a separate source and now the meter is reading 34 volts even though the power supply output is actually 12.4 volts. Tried powering it on/off/on a few times but did not fix it. With the meter input grounded, it is reading a negative voltage. Confirmed the actual input V with one of my Fluke meters. Definitely has failed. ## Features - ☛Voltmeter Digital Voltage Meter: This product is fully functional, you can display the battery voltage; Measurement range: DC: 0.000-33.000V - ☛ Refresh rate: 5 times per second; Measurement accuracy: ±0.3‰ - ☛Digital Voltmeter Display: High brightness LED display, easy and clear to read - ☛Easy to Use: Mini size and easy to install, work great for checking voltage and battery power - ☛Dimensions: 48mm*29mm*22mm; Opening size: 45mm*26mm ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08N45HMCJ | | Best Sellers Rank | #407,250 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #345 in Voltage Testers | | Brand Name | T-HOT | | Color | Red | | Customer Reviews | 3.7 3.7 out of 5 stars (22) | | Item Dimensions | 3.15 x 2.36 x 0.79 inches | | Item Weight | 0.02 Kilograms | | Manufacturer | T-HOT | | Measurement Type | Voltmeter | | Minimum Operating Voltage | 4 Volts (DC) | | Model | 1AA800504 | | Power Source | Corded Electric | | Style Name | Digital | | Upper Temperature Rating | 65 Degrees Celsius | ## Product Details - **Brand:** T-HOT - **Color:** Red - **Item Weight:** 0.02 Kilograms - **Power Source:** Corded Electric - **Style:** Digital ## Images ![T-HOT Digital Voltmeter DC Voltage Display 0-33.000V (0-33V) 5-Digits Bit High Precision Voltage Meter - Image 1](https://m.media-amazon.com/images/I/614v8+1BnfL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Technical Review *by S***S on June 6, 2023* TL;DR - Accuracy is much greater than the spec.

And it has already failed. Was using it to monitor a 12v power supply with the meter powered from a separate source and now the meter is reading 34 volts even though the power supply output is actually 12.4 volts.

Definitely has failed. ### ⭐⭐⭐⭐⭐ EXCELLENT, Hi-Res, panel Voltmeter *by M***M on May 18, 2025* I am very impressed. The readings are spot on when measuring 12V and 24V, at millivolt resolution, compared to my CALIBRATED DMM's. Run them off a 9V battery to isolate from DUT (device under test). Only downside is that two of these meters will kill a 9V battery in one day, if you leave them ON. ## Frequently Bought Together - T-HOT Digital Voltmeter DC Voltage Display 0-33.000V (0-33V) 5-Digits Bit High Precision Voltage Meter - Taidacent Blue Color High Precision 5 Digit Amp Meter DC 0.0000-3.0000A Ammeter Digital Display DC Digital Ammeter Resolution 0.1mA - Eaglerich Mini Car LED Display Digital Voltmeter DC 4-30V 0.36" 5 Digit Voltage Panel Meter Red 3 Wires --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/307509492-t-hot-digital-voltmeter-dc-voltage-display-0-33-000v](https://www.desertcart.pl/products/307509492-t-hot-digital-voltmeter-dc-voltage-display-0-33-000v) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-14*
