![]() ![]() For the price, it’s reliable and multi-purpose. This meter is a great way to monitor your relationship with your electronics. It will increase your devices’ lifespans and notify you when to get better chargers. DROK is significantly less expensive than competitors like the PortPilot so it’s an economical purchase. With almost everything charging from USB ports today, this device can be a useful tool. PH2.0 terminal conductor, connected to PCB opposite connector. Personally, this is a minor flaw and doesn’t necessarily negate the usefulness of the device. It also doesn’t shut off which is a pro for some and a con for others because the display takes a small amount of charging current (<20mA) to power. Also, keep in mind that “capacitance” mean watt-hours transferred.ĭisplay-wise it’s hard to see in bright sunlight, which is a pain if you’re testing solar panels. The manual isn’t straightforward and only tells you what the display shows. What doesn’t make it accessible are the instructions. It’s fun to charge your phone to 100% while learning how settings like screen brightness affect power.īut there are also some minor cons. The pro of the display is the clear, dual-LED screen so it’s easy to see indoors. I was pleased to see the larger AWG wire I used for USB power leads in the new cables improved charging current. ![]() I swapped separate cables between a fixed charger, the Drok, and a battery being charged and simply read the meter. Although voltage and amperage readings are on other devices, the power and MAh draw are bonus touches.Īnother positive is that you can easily determine voltage drop of some new and “heavy duty” USB cables. ![]() The power draw is less than 10mA and doesn’t significantly load test devices or PSU. Plus, you can view the voltage and current values at the same time. This universal meter is perfect for either original or non-original chargers (like solar), mobile phones, tablet PCS and other USB devices like BC1.2 yt/d1591-2009 and non-BC1.2 gadgets including iPad, iPhone, and the Samsung Galaxy.ĭROK’s charging current is determined by compatibility. Seven testing modes provide information on capacitance, power, voltage, and amps. The second output is a built-in smart charging control IC that automatically matches the safest and correct currents for your devices. Output I offers the dual function of charging and data transfer. ![]() With a lightweight design of 2.4 ounces and dimensions 2.7’’ x 1’’’ x 0.6’’, the DROK 2.0 is easily portable, compact, and versatile. Sorting sub-par cables and chargers from the useless ones becomes easier to power through.ĭROK makes life a bit easier. You can see the drop in voltage as the device reads your supply while charging the current. The meter monitors output differences of any USB port. The model allows you to test USB port problems and the charging capability of old or third party chargers and outlets. I don’t have time to play the guessing game of how much power my USB is drawing. Alarm: Meter flashes to alert you when voltage or current exceeds preset limits The alarm function will also alert you when your battery bank charge is low.There’s nothing more aggravating than having a full battery in the morning only to find it completely drained when you really need it.Display: Backlit wide-viewing-angle LCD display allows you to read the monitor easily, even in bright sunlight.Hall Sensor & Easy Mount: The meter is designed for easy installation in either two or three wire configurations with its Hall Sensor design.Voltage measurement range is DC 0-300V, current measurement range is 0-200A.Track percentage of battery capacity remaining, DC current, DC voltage, and more. Multifunctional Meter: This multi-function system meter allows you to easily monitor multiple system parameters at a glance.In the event power is lost, the meter will even save your data so important system performance information won’t be lost. Compatible with many kinds of batteries, including Lead-acid batteries, Lithium Polymer batteries, lithium iron phosphate batteries. The Drok D-BEM DC system meter can be used as a DC amp meter, digital volt meter, power meter, and battery bank capacity monitor. ![]()
