Your feedback is not only important to us but also beneficial to other customers, therefore we’d like to invite you to submit a review for the Tekpower power supply!. Review: Exceeded expectations - Easy to use, clean power, solid regulation, and accurate. It outputs a maximum of 3.75 amps or 50 watts, whichever is lower. e.g. 3.33 amps at 15 volts, 2..08 amps at 24 volts, or 1.67 amps at 30 v. There's a software calibration mode but mine was spot on to my DVM, within a few hundredths of a volt so I didn't bother with it. The USB outputs are fixed at 5.1 v (a good thing) but you can set current limits at anything up to 2.5 amps and monitor actual current. Minor quibbles: The manual is poorly translated but the interface is pretty intuitive. The power button just controls the output so the unit stays on as long it's getting AC. Build quality is excellent overall but the included output leads are crappy. Much more compact and handy than an equivalent linear power supply. Highly recommended. Review: Unprofessional desertcart - The item is correct however the seller as well as desertcart both had irresponsible behaviour. Despite non delivery complaints desertcart did not do anything nor they called to know the status. desertcart has proved to be unreliable and unprofessional b2b seller. ## Features - Word First Handheld Power Supply with precision CC and CV,0-30 volts@ 0-1.6 amp or 0-12V @4.0A - 4 digits LCD display,Output short circuit protection, - High speed dynamic response,Once power cut-off, automatically protect under power off status - The output has the automatic recognition of USB charging port,Can be calibrated via software operation - Tekpower TP3016M Portable Handheld Variable DC Power Supply with USB Port, 0.3V 12V @ 0 3.75A or 0.3V 30V@ 1.6A with VC and CC Control, Upgraded TP3005D,HY3005, Mastech - Item Package Quantity: 1 - Number of Items: 1 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B015OA1J82 | | Amperage | 3.75 Amps | | Brand | Tekpower | | Customer Reviews | 4.3 out of 5 stars 110 Reviews | | Form Factor | handheld | | Form factor | handheld | | Item Dimensions | 7.6 x 3 x 17.8 centimeters | | Item Weight | 0.39 Kilograms | | Item dimensions L x W x H | 7.6 x 3 x 17.8 centimeters | | Item weight | 0.39 Kilograms | | Manufacturer | Tekpower | | Mfr Part Number | TP3016 | | Model Number | TP3016M | | Output Current | 4 Amps | | Output current | 4 Amps | | UPC | 857852005451 | | Unit Count | 1 Count | ## Product Details - **Brand:** Tekpower - **Item dimensions L x W x H:** 7.6 x 3 x 17.8 centimeters - **Item weight:** 0.39 Kilograms - **UPC:** 857852005451 ## Images ![Tekpower TP3016M Portable Handheld Variable DC Power Supply with USB Port 0.3V - 12V @ 0 - 3.75A or 0.3V-30V@ 1.6A with VC and CC Control Upgraded TP3005DHY3005 Mastech - Image 1](https://m.media-amazon.com/images/I/41buxS1HiEL.jpg) ![Tekpower TP3016M Portable Handheld Variable DC Power Supply with USB Port 0.3V - 12V @ 0 - 3.75A or 0.3V-30V@ 1.6A with VC and CC Control Upgraded TP3005DHY3005 Mastech - Image 2](https://m.media-amazon.com/images/I/710DY78U5VL.jpg) ![Tekpower TP3016M Portable Handheld Variable DC Power Supply with USB Port 0.3V - 12V @ 0 - 3.75A or 0.3V-30V@ 1.6A with VC and CC Control Upgraded TP3005DHY3005 Mastech - Image 3](https://m.media-amazon.com/images/I/81HBSCGOQML.jpg) ![Tekpower TP3016M Portable Handheld Variable DC Power Supply with USB Port 0.3V - 12V @ 0 - 3.75A or 0.3V-30V@ 1.6A with VC and CC Control Upgraded TP3005DHY3005 Mastech - Image 4](https://m.media-amazon.com/images/I/91mWYVhx9mL.jpg) ![Tekpower TP3016M Portable Handheld Variable DC Power Supply with USB Port 0.3V - 12V @ 0 - 3.75A or 0.3V-30V@ 1.6A with VC and CC Control Upgraded TP3005DHY3005 Mastech - Image 5](https://m.media-amazon.com/images/I/91dyiTKUfIL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Exceeded expectations *by L***S on 19 February 2016* Easy to use, clean power, solid regulation, and accurate.

Despite non delivery complaints Amazon did not do anything nor they called to know the status. Amazon has proved to be unreliable and unprofessional b2b seller. ### ⭐ Avoid. *by P***R on 10 July 2017* A power supply with no power switch? Yup. A button that sets it to +5v, 2.5A with one accidental touch? Yup. Random voltages, including negative on the outputs? Why not. ## Frequently Bought Together - Tekpower TP3016M Portable Handheld Variable DC Power Supply with USB Port 0.3V - 12V @ 0-3.75A or 0.3V-30V@ 1.6A with VC and CC Control - Elenco TL-12 Banana to Mingrabber Set --- ## 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.at/products/712366378-tekpower-tp3016m-portable-handheld-variable-dc-power-supply-with-usb](https://www.desertcart.at/products/712366378-tekpower-tp3016m-portable-handheld-variable-dc-power-supply-with-usb) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-07-22*
