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 - 【Calibration】 The ZK-DP2 is an adjustable DC power supply module with digital LED tube display. It can calibrate the output voltage and the output current. And it can also be used as a normal power supply module, charger and LED constant current driver. - 【Characteristics】 4-bit digital tube display. Three input power modes. High resolution. Several parameters can be displayed. Comfortable outer shell. - 【Protective function】 Supports overvoltage protection, overcurrent protection, overpower protection and overtemperature protection. - 【Wide range of application】 It is widely used in ordinary power supply, battery charger, LED driving power, instrument voltage display, test counter, circuit test, power conversion. ❤️❤️❤️ For detailed instructions, see the link: http://attach01.oss-us-west-1.aliyuncs.com/IC/Datasheet/13452.pdf - 【Note】 This is a DC power module that can not be connected to AC power. Please no short circuit. "IN" and "OUT" can not be connected. Otherwise, the module can not support a constant current output. Make sure the input power is more than the load power. Please turn off the output power when the module is hot. Turn the CV potentiometer counterclockwise more than 10 turns when the output turns off ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07V5FPNNZ | | Best Sellers Rank | #165,367 in Electronics ( See Top 100 in Electronics ) #1,516 in International Power Adapters | | Brand | PEMENOL | | Brand Name | PEMENOL | | Current Rating | 2 Amps | | Current rating | 2 Amps | | Customer Reviews | 4.4 out of 5 stars 101 Reviews | | Item Weight | 1.76 Ounces | | Item weight | 1.76 Ounces | | Manufacturer | PEMENOL | | Model | 13452 | | Part Number | 13452 | | Power Source | Dc Power Supply | | Power source | Dc Power Supply | | Specification Met | RoHS | | Specification met | RoHS | | UPC | 608651949350 | ## Product Details - **Brand:** PEMENOL - **Current rating:** 2 Amps - **Item weight:** 1.76 Ounces - **Power source:** Dc Power Supply - **Specification met:** RoHS ## Images ![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 - Image 1](https://m.media-amazon.com/images/I/71Nzj9oT9cL.jpg) ![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 - Image 2](https://m.media-amazon.com/images/I/61VgxKV4HSS.jpg) ![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 - Image 3](https://m.media-amazon.com/images/I/51iIVgA2RfS.jpg) ![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 - Image 4](https://m.media-amazon.com/images/I/71yw454fuZS.jpg) ![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 - Image 5](https://m.media-amazon.com/images/I/81fGTvCnNpL.jpg) ## Available Options This product comes in different **Style** options. ## Questions & Answers **Q: Can this can take an input of 5v 2.1a and output 30v 2.5a, and is the set output stable?** A: No, not unless I have overlooked what would be a very valuable feature. 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 8 September 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.tn/products/264199304-pemenol-15w-dc-dc-buck-boost-voltage-converter-5v-to](https://www.desertcart.tn/products/264199304-pemenol-15w-dc-dc-buck-boost-voltage-converter-5v-to) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-17*
