Great addition to my 290w 36v solar panels. Mine shuts down around 5.9v, but it remembers the cumulative energy. UPDATE: After 4 months, it started reading wildly high voltages, current was still correct. Finally I contacted DROK, and they wrote me a helpful email within 24 hours. Bonus points for them for being responsive and knowledgeable. The 20A version can be recalibrated. The difficult parts are soldering a switch to the internal contacts on the board and finding a 20.0v 1A power supply and 20 ohm 20w resistor. I did, and it calibrated within about 5 seconds. Dear customer, If it is possible, would you please try to calibrate it with following method. 1. Turn off the power supply. 2. Connecting power supply (20V/1A) and load. 3. Short connect two calibrating spots (Open the back cover, you can find two holes which marked by “W” on the edge of board) 4. Turn on the power supply. 5. When the screen display changed from “CAL---“ into” ---PASS”, that means the calibration is finished. Any more questions, please let us know. Best regards, DROK Review: Easy to install works as designed. - Added a 12v RV AC unit and wanted to monitor the amp draw. What a simple and great monitor. Easy to wire and use for battery draw tracking. ## Features - PARAMETER ---- voltage test range DC 8~100V; current test range 0~100A; power test range 0~10kw; battery level test range 0~9999kwh. - DATA GUARANTEED ---- with power-off storage function, all parameter will be stored automatically when powered off; accumulated energy data can be reset. - OVER-VOLTAGE ALARM & SETTABLE ALARM VOLTAGE ---- if active power is larger than threshold, backlight and power will flash as an indicator. - LARGE-SCREEN LCD ---- display voltage, current, power, energy at the same time. - SWITCHABLE BACKLIGHT ---- backlight can be turned on/off manually. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07KPXVNY5 | | Best Sellers Rank | #119,691 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #159 in Multi Testers | | Brand Name | DROK | | Color | Blue | | Customer Reviews | 4.3 4.3 out of 5 stars (1,110) | | Included Components | no | | Item Dimensions | 3.53 x 1.95 x 0.96 inches | | Manufacturer | DROK | | Measurement Type | Ammeter, Multimeter, Voltmeter | | Minimum Operating Voltage | 8 | | Model | 200141 | | Power Source | Battery Powered | | Style Name | 100A | | Unit Count | 1 Count | ## Product Details - **Brand:** DROK - **Color:** Blue - **Item dimensions L x W x H:** 3.53 x 1.95 x 0.96 inches - **Power Source:** Battery Powered - **Style:** 100A ## Images ![DROK DC Power Meter, 8-100V 100A Volt Amp Watt Meter, LCD Display Multimeter Voltage Current Energy RV Battery Monitor Voltmeter Ammeter Wattmeter with 100A Battery Shunt - Image 1](https://m.media-amazon.com/images/I/71AtOaSMvaL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Questions & Answers **Q: If I use 4 shunts in parallel, would device show 1/4 of actual current flow ? I need to measure up to 400 A draw.** A: Yes Considering the shunts as resistors, they obey the 1/R law. If each shunt of 1 ohm then 1/R= 1/1+1/1+1/1+1/1 1/R=4 R=1/4 then I =V across shunts/(1/4) This should hold true for the real world. Remember Voltage = (I)(R) **Q: What would happen with an occasional 200a draw? Would it just not measure it correctly or would it be permanently broken?** A: Whereas I have not personally exceeded the maximum reading capability of this particular instrument, I have done so with many, many other ammeters, digital and analog with no consequence as long as the amount and time of overload is reasonable. The actual current being utilized by the meter's internal circuitry is in the micro amp range with little chance of heat damage. I'd assume that an overload indication such as a flashing display or , "err", "hhh" or "ovr" would be displayed. **Q: Does this meter give a constant amp readout, and if I am using a 48 v system does the meter need a separate power supply?** A: The meter does displayed a constant current reading. The supply voltage you are providing to your device will also run the meter no need for a separate power supply. **Q: When used to measure the voltage and amperes fed to the battery as opposed to battery output can/should you leave out the shut? 1 output side also.** A: Dear customer, If you are going to monitor battery, please connect it to the "Load" position. Meter have to work with shunt.

Easy to wire and use for battery draw tracking. ### ⭐⭐⭐⭐ Best cheap shunt on the market. *by H***R on May 25, 2025* I've got a few of these in my go boxes and RV. I love that they are simple, basic and just work. I also love that they have a watt hour use meter that can be reset to count again. A feature all shunts should have, but most don't. It's fairly accurate when measured against my Fluke 289 but off a few 10s of mV. It has higher resolution at 10mV and 10mA than most shunts. I wish it had "bi directional" readings so could read charge and discharge and I wish the shunt itself had holes in it to better mount. Lastly the 50A version is no longer available, but great for smaller installs. But even with the small draw backs this is a great shunt for the money. If you are wanting bi directional or SOC (which is never really accurate anyway) this may not be the shunt for you. ## Frequently Bought Together - DROK DC Power Meter, 6.5-100V 100A 12V 24V 36V 48V 60V 72V Volt Amp Watt Meter, LCD Display Multimeter Voltage Current Energy RV Battery Monitor Voltmeter Ammeter Wattmeter Panel with 100A Shunt - DROK DC 4.5-100V Digital Voltmeter Ammeter Multimeter Panel, DC Amp Meter Voltage Meter, Current Meter 0-50A Volt Tester, LED Display Voltage Gauge for Automotive Motor Battery --- ## 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.uy/products/94255191-drok-dc-power-meter-8-100v-100a-volt-amp-watt](https://www.desertcart.uy/products/94255191-drok-dc-power-meter-8-100v-100a-volt-amp-watt) --- *Product available on Desertcart Uruguay* *Store origin: UY* *Last updated: 2026-04-23*
