Provides plenty of power. The adjustability is great, but the mode select is... not. Review: Easy to adjust - I purchased this to replace the missing power supply on My weather-band radio. I needed 11.4 volts. The new power supply was a lot of money. This works perfect. This Buck converter can be used to charge lithium batteries. Input voltage can be adjusted up or down. Input 4 to 13vDC and the output .5 to 30VDC. Easley done pressing buttons and watching LCD. I can use it to power it on other items. Easy enough. It is also can be used as a battery charger for Lipo batteries. Did this also when my RC battery charger failed. This is a lot of Bang for the BUCK. ( no pun intended. ## Features - ★The Output Voltage Can Be Adjusted Arbitrarily: The Adjustable USB Step Up Down Power Supply Module used as a USB input adjustable desktop power supply, the output voltage can be adjusted arbitrarily, and the current limit is 0-2A (wide input 4-13V, wide output 0.5-30V arbitrarily adjusted, with short circuit protection, the short circuit does not burn) - ★Safe to Use: Used as a USB charging cable, the charging voltage and maximum charging current can be adjusted arbitrarily (any voltage, with constant current, anti-backflow, which can meet the charging of most batteries) - ★Three Input Power Modes: Input 1: Standard Type A USB Male. It just can input DC 5V. Input 2: Micro USB Female. It just can input DC 5V. Input 3: IN+ and IN- welding pads. It can input DC 4.0V-13.0V. When using the welding pad to input, be careful not to connect the reversed positive and negative poles, and do not connect to AC power - ★Multiple Protection Functions: short-circuit, over-current, over-temperature, over-power, over-voltage protection, charging anti-backflow protection - ★Wide Application: It is widely used in ordinary power supply, battery charger, LED driving power, instrument voltage display, test counter, circuit test, power conversion.

If we assume 100% efficiency for conversion, 2.1 Amps at 5 Volts would give you only 0.35 Amps at 30 Volts, more realistically it would be much less than that since the conversion will not be 100% efficient . 30V * 2.5A= 75 Watts, 5V * 2.1A = 10.5Watts I hope this helps. Please forgive me if I have misunderstood the question. **Q: Can one use this to “trickle “ charge a motorcycle battery?** A: The previous answer is incorrect. Yes, it absolutely would. In fact, its current handling capacity (~1A or so) would be more than enough to charge a motorcycle battery (12-24 hours), let alone maintain it. However, since it isn't programmable, you wouldn't get the benefit of occasional absorption cycles to prevent sulfation. Nevertheless, you could winter float a 300Ah 8D with this thing with no issues. **Q: Does the usb in ports support data pass through to the usb out ports?** A: Not supported, it is a power converter and does not support data communication **Q: Does this display delivered current in real time?** A: With multiple sets of fading LEDs, I'm observing about 2 current updates per second ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works flawlessly, auto-on with input power a big plus! *by M***. on September 8, 2025* Used to power a 7" plasma ball for a wizard staff project.

I control a pump and this works flawless. Update: Directly to the battery is fine. I had the Red USB power blow out/smoke during an ERR/OPP twice before I could turn it off and nothing was connected. The solar charger 12v output it was connected to fried the device. ## Frequently Bought Together - PEMENOL 15W DC-DC Buck Boost Voltage Converter, 5V to 3.3V 9V 12V 24V 30V CVCC Step Up/Down Module Adjustable USB Power Supply Module with Shell - jojofuny 4pcs Led Filament 300mm Retro Bulb Accessories - Flexible Filament Light Repair --- ## 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.jp/products/147300205-pemenol-15w-dc-dc-buck-boost-voltage-converter-5v-to](https://www.desertcart.jp/products/147300205-pemenol-15w-dc-dc-buck-boost-voltage-converter-5v-to) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-07-21*
