A compact BISS-class digital voltmeter and ammeter designed for simultaneous DC voltage and current monitoring on batteries, vehicles and bench projects. The Exqutoo Voltmeter Ammeter uses a dual-colour 0.28-inch LED panel to present readings clearly, helping hobbyists and technicians avoid guesswork. Is the unit accurate and robust enough for regular workshop use?
⚡ At a Glance
- • Display: 0.28-inch red and blue LED panel with clear numeric readout
- • Best for: Hobbyists, EV owners and technicians monitoring DC systems and batteries
- • Not ideal for: AC measurements or circuits exceeding the 0–100V or 0–10A ranges
Dual-colour LED presents simultaneous DC voltage (0–100V) and current (0–10A) readings. Powered from DC 4–30V with a refresh rate of about 300ms per reading.
Clear simultaneous readouts – thanks to the red & blue 0.28-inch LED display
A dual-colour LED panel shows voltage and current values side by side with a refresh rate of approximately 300ms. Numeric digits are updated frequently to reflect real-time changes in DC circuits.
Quick visual checks replace frequent multimeter swapping, speeding up battery tests and in-vehicle diagnostics. The distinct colours reduce readout confusion when monitoring two parameters at once.
Wide DC compatibility – with 0–100V voltage and 0–10A current ranges
Voltage measurement covers DC 0–100V while current measurement covers DC 0–10A, suitable for many rechargeable batteries and small-vehicle systems. The meter requires a separate power input within DC 4–30V, with a strict maximum of 30V for the power supply input.
Suitable for bench power supplies, electric bikes, motorcycles and small marine applications within those limits. Users must ensure the power supply input stays within 4–30V to avoid damaging the meter.
Compact installable panel – with a small 48 x 29 x 22 mm footprint
The meter combines metal and plastic construction in a compact housing sized at 48 x 29 x 22 mm and operates between -10°C and 65°C. Working current is low, at ≤20mA, and the unit is described as a 2-in-1 volt amp meter.
Easy to mount into instrument panels or DIY enclosures where space is limited. Low power draw keeps the meter suitable for battery-powered test rigs without significant drain.
✨ The 4 Key Reasons for Exqutoo Voltmeter Ammeter

❓ Frequently Asked Questions
Q: Can the meter measure AC voltage?
A: No. Measurements are specified for DC only, with a DC voltage range of 0–100V.
Q: What power supply does the meter need to operate?
A: A DC supply between 4V and 30V is required for the meter’s power input, and the maximum input voltage must not exceed 30V.
Q: Can the meter measure currents above 10A?
A: No. The current measurement range is DC 0–10A, so higher currents are outside the specified range.
🏆 Our Verdict
The Exqutoo Voltmeter Ammeter suits hobbyists, EV owners and technicians who need compact, simultaneous DC voltage and current readings. Clear dual-colour readouts, a practical measurement range and low working current make it a handy choice for bench and vehicle checks. Given the build and practical limits, the unit represents solid long-term value for regular workshop and field use.
