It also has a 5V USB port that can provide a maximum of up to 2.4A current, which is enough to charge and power many cell phones and tablets. - Accept wide range DC input voltage: from 9V to 30V; Maximum total output up to 90W. 5V USB port maximum output up to 2.4A; - Super high converting efficiency: up to 96%. A regular DC converter efficiency is around 80% ~ 85%, which means 15% ~ 20% power will be used by converter itself. For a 85% efficiency rate power adapter to deliver 90W power, it will take 106W power from power source ( such as a battery). This DC Converter efficiency rate is up to 96%, which means only around 4% power will be used by converter itself. To deliver 90W power, it only needs 94W power from power source. - Super small size: dimension is 2.5" x 1.9" x 0.7" ( 63.5*48.9*16.9mm). Super light weight: only 2.54 oz ( or 72g); - Package comes with one BiXPower DD90M 90W Mini Size DC to DC Power Adapter and one 19V Output Cable ## Product Details - **Brand:** BiXPower - **Color:** Black - **Item Weight:** 2.5 Ounces - **Input Voltage:** 30 Volts - **Item dimensions L x W x H:** 2.5 x 1.9 x 0.7 inches ## Images ![12V to 19V and 5V USB Mini Size High Efficiency 90W DC to DC Power Converter DD90M-19V - Image 1](https://m.media-amazon.com/images/I/31XdyLXTPqL.jpg) ## Questions & Answers **Q: Does the output connector have a center pin (positive) that fits Samsung TVs?** A: No, the output connector is standard 5.5 x 2.5mm barrel connector, does not have a center pin. You will need a connector tip from BiXPower to change the standard 5.5 x 2.5mm connector to Samsung TV special connector. Different Samsung TVs may have different size connector, mostly likely will need BiXPower CNT-C6 or CNT-C2 connector tip. **Q: Will this work for a nuc bean canyon 8th gen?** A: Output voltage and wattage will meet nuc bean canyon 8th gen requirement. However, this converter does not generate any power, you need to make sure the 12V power source that connected to the converter can provide 95W or more power in order to output 90W power. The standard connector on output cable is 5.5 x 2.5mm male connector. If this size does not fit nuc bean canyon 8th gen, you may need to order an optional connector tip from BiXPower that can change the 5.5 x 2.5mm size to the size. that will fit. **Q: I have a asus laptop that operates with a dc of 19v and 1.75 amp. need cablethat is usb on one end & 5.5m barrel jack on the other.will this item work** A: This power adapter output is 19V. It has no problem to run a Asus laptop that needs 19V 1.75Amp power. However, this is not a battery, it is just a voltage converter. In order to power your Asus with this power adapter, you need to connect a 12V ( range 10V ~ 17V) battery or other 12V power source to the power adapter input port.Best regards.BiXNet **Q: Can i use this to power a 5v/1.5a usb device and 12v/4a peripheral at the same time?** A: If the output is 5v, obviously you cannot power a peripheral that requires 12v with that output. You might, however, be able to tie into the same 12v source used by the BiXpower. If you are planning to use this in a boat or vehicle, the nominal 12v source could actually be anywhere between 11 and 16v which could destroy your peripheral. ## Customer Reviews ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Just what I needed, and very small *by B***N on Reviewed in the United States on February 28, 2016* Great little DC converter. Very small. I got this to ensure my Intel NUC computer had a full 19V when running it off a 12V battery. Although the NUC is rated to run off anything between 12V and 19V, I was a little worried if the 12V source were to drop below 12V. The output power cord which comes with the BiXPower is a 5.5mm x 2.5mm and fits directly into the NUC. The input socket on the BiXPower is the same size as well. It's so small I can just velcro it onto the Intel NUC chassis.I was a little hesitant because of the price, but it's exactly what I needed and I have not seen any other DC converter in this small form factor. ### ⭐⭐ 2.0 out of 5 stars worked well until it died *by P***G on Reviewed in the United States on September 24, 2019* died after about 9 months and about 10 uses. last use: It didn't like running at about 80W for 5 or 6 hours. Works well if using it for shorter durations ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Just what I needed *by D***M on Reviewed in the United States on May 23, 2019* This DC power converter was purchased to power a 19V TV in my RV, and it worked right away. Luckily, I had an adapter from a universal PC power supply that allowed the hook up to the TV. --- ## 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.sc/products/14023700-12v-to-19v-and-5v-usb-mini-size-high-efficiency](https://www.desertcart.sc/products/14023700-12v-to-19v-and-5v-usb-mini-size-high-efficiency) --- *Product available on Desertcart Seychelles* *Store origin: SC* *Last updated: 2026-09-04*
