Power: 0-10KW Test Range, within 1KW, 0.0-999.9W; 1KW and above, 1000-9999W 2. Energy: 0-9999KWh Test Range, within 10KWh, 0-9999Wh; 10KWh and above, 10-9999KWh 3. Voltage: 6.5-100V, it shows 6.50-99.99V 4. Current: 0-100A, it shows 0.00-99.99A Notices 1. Wiring order cannot be wrong.The shunt CAN'T be placed on the positive side. You can connect it near the battery negative or near the load negative according to youre convenience. 2. This meter is suitable for indoor use ONLY. 3. Applied load should not exceed the rated power or current. 4. "All 888s display" are mostly caused by wrong wiring and caused by the interference from load. 5."Zero current" issue are mostly caused due to wrong wiring. Connect a most simple battery-shunt-load circuit to test the meter first. 6.As there's no large current flowing through the meter, any 30AWG-12AWG copper wires are suitable. 7. Need a pointing tool to press the function button to prevent accidental touch. 8.The wire harness is NOT included. Specification Working Voltage: 6.5-100V/DC Measuring Accuracy: 1.0 grade Power Consumption: 0.2W Measuring Speed: 2 times/s Meter Dimensions: 9.0x5.0x2.4cm Shunt Dimensions:10.5x3.0x2.2cm Package included： 1x DC Digital Multimeter 1x 100A/75mV Current Shunt Applications Some portable 12V power boxes you can make, use these power meters to monitor the load on the power supply and see the current charge level so you know when to replace them. This volt and ammeter can be mounted on an RV, you can easily see what the electrical system is doing, you can also know what the current draw of loads such as lights, water pumps, standard dorm refrigerators, etc., and the watt-hour meter can let you know the battery How much has been exhausted. There are several systems you can build that use an off-grid solar system to track how much solar energy is created and used. It's easy to read and hardly ever uses any power alone, even with the backlight on. Solar System Wiring Instruction NO.1 meter monitors the performance of the solar power producing. NO.2 meter monitors the charging performance, Note: When the bettery is discharging. #2 meter displays ZERO current and ZERO power reedings. The energy stops accumulating. The energy starts accumulating once it's charging. NO.3 meter monitors the discharging performance. Note: When the battery is charging. #3 meter displays ZERO current and ZERO power readings. The energy stops accurmulating. The energy starts accumulating once it's discharging. NO.4 meter measures the load usage. Wiring Instruction Monitor RV Battery Wire NO.1 meter to monitor charging performance of the battery. Wire NO.2 meter to monitor discharging performance, . Wire both meters on one shunt to monitor charging and discharging performance. Review: All good. Would buy again - Done the job for the project I was building Review: Battery Status Monitor - This device looks good and performs exactly as per the specification. Well made plastic housing. I fitted the device into an electrical twin junction box which tidied up and concealed the wiring. ## Features - Voltage test range DC 6.5~100V; current test range 0~100A; power test range 0~10kw; battery level test range 0~9999kwh. - Power-off storage function, all parameter will be stored automatically when powered off; accumulated energy data can be reset. - If active power is larger than threshold, backlight and power will flash as an indicator.Backlight can be turned on/off manually. - Display voltage, current, power, energy at the same time. - If there is any question,please feel free to contact us,we will do our best to help you solve the problem. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0B87458J7 | | Best Sellers Rank | 254,300 in DIY & Tools ( See Top 100 in DIY & Tools ) 358 in Voltage Testers | | Brand | Voktta | | Colour | black | | Country Of Origin | China | | Customer Reviews | 4.4 out of 5 stars 130 Reviews | | Included Components | DC Power Meter 6.5-100V 100A,100A/50mV Shunt | | Item Dimensions | 10 x 10 x 10 millimetres | | Item dimensions L x W x H | 10 x 10 x 10 millimetres | | Manufacturer | Voktta | | Manufacturer Part Number | VKX-JL0270A | | Maximum Operating Voltage | 100 Volts | | Measurement Type | Ammeter, Multimeter, Voltmeter | | Min.

Would buy again *by C***L on 3 July 2026* Done the job for the project I was building ### ⭐⭐⭐⭐⭐ Battery Status Monitor *by M***L on 25 July 2023* This device looks good and performs exactly as per the specification. Well made plastic housing. I fitted the device into an electrical twin junction box which tidied up and concealed the wiring. ### ⭐⭐⭐⭐ Works, but reads voltage a little low *by S***. on 22 June 2026* It works, but the voltage displayed is under voltage, I can only know this as I have other voltage measuring devices before and after this device, and they both read higher. Another thing to consider which could be improved is the current shunt, the bolts are for electrical connections, so there is no way to mount the shunt securely, which makes it difficult when it’s behind a panel, and you want to know it’s not going to short out to anything, even if it’s on the negative side of the circuit, it’s just poor to not have the ability to mount it. Other than that it works as intended so far for my off grid solar setup. Instructions would also have been good, regarding how to alter settings and reset the Wh count, which I still have no clue how to do. ## Frequently Bought Together - VOKTTA Digital Voltmeter Ammeter DC 6.5-100V 100A Power Meter,LCD Display Multimeter Voltage Current Energy RV Monitor Wattmeter Panel with 100A/75mA Shunt - Bolatus Battery Isolator Switch 12V 24V 48V Battery Switch 275A Battery Kill Switch 1-2-Both-OFF Battery Cut Off Switch for Car Truck Boat Yacht Caravan Motorcycle - Gorffy Battery Terminal Connectors 130 Pcs, Battery Terminals Tinned Copper, Cable Lugs Bolt Hole, Crimp Battery Cable Connectors, Battery Crimp Terminals for Electric, Auto --- ## 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.co/products/472406486-digital-voltmeter-ammeter-dc-6-5-100v-100a-power-meter](https://www.desertcart.co/products/472406486-digital-voltmeter-ammeter-dc-6-5-100v-100a-power-meter) --- *Product available on Desertcart Colombia* *Store origin: CO* *Last updated: 2026-08-26*
