Do you know how much power your USB charging sticks actually hold? JVR TL59 OLED USB Power Meter can help you easily identify the best cables for USB charging. It shows the voltage, watts, amperage, and the mAh being delivered to your devices. Bright clear display is easy to read and rotation screen for best review. *USB Charging Monitor TL59 shows 4 essentials simultaneously, current, voltage, power and capacity. It is a handy gadget for discovering how much power your USB ports will put out, how much your device will actually draw, how much it takes to fully charge a device, etc. *OLED Screen 0.91inch OLED display is bright enough to see both indoor and outdoor. Current, voltage, and power (current multiplied by voltage) are continuously displayed, and capacity (in mAh) accumulates as long as the input power remains on. *Milliampere Accumulator JVR tester has an accumulator for the number of milliampere-hours of current that have passed through the device. When powered up again, the accumulator flashes the total number of the last test until the new device under test has drawn 1 mAh. *Voltage Reminding When the voltage is less than 4.7 or greater than 5.3 volts, the arrow will be flashing to remind the voltage is too low or too high. Only when the voltage becomes to 4.7-5.3V, the arrow can be disappeared. *Display Flip The readout can be flipped in case you have to plug it in "upside down". The screen rotation button is behind the center perforation. Just press the button, the display will be inverted.

First photo shows another brand of USB monitor and the load (a battery charger, in this case). Note how the load has two red charging lights lit? And that the USB monitor indicates 0.24A being supplied to the load? The second photo shows this model USB charger under review. Note the load lights are off? Note the current on the USB monitor is zero? The unit simply isn't functioning. ### ⭐⭐⭐⭐⭐ Simple & Functional *by D***N on Reviewed in the United States on September 23, 2016* After I lost an earlier version of this tester, I replaced it with this model. A big improvement is the ability to retain a capacity reading when a battery pack is discharged to depletion for testing and everything shuts off - something my earlier model lacked. Otherwise the display is clearly visible and the device gives readings for voltage, current draw, power, and most importantly milliamp-hour capacity. It's a simple and straightforward tool. ### ⭐⭐⭐⭐ Works well, excellent tester. *by A***H on Reviewed in the United States on December 29, 2016* I have been using this to measure the output of the USB chargers. Has helped me couple of times to identify fake and faulty chargers. Worth to have one. --- ## 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.ph/products/24216763-voltage-tester-for-usb-2-0-4-in-1-oled](https://www.desertcart.ph/products/24216763-voltage-tester-for-usb-2-0-4-in-1-oled) --- *Product available on Desertcart Philippines* *Store origin: PH* *Last updated: 2026-04-22*
