It also includes a short polarity switch cable to give flexibility of either centre -ive or +ive to suit your device 9vdc requirements. Important you get this right for most electronics to avoid possible damage from incorrect dc polarity. Also check your device current draw/rating is within the plugs output rating (measured in amps or milliamps). I use it for guitar effects pedals so is perfect for alternative to eating standard 9vac batteries. **Q: Is this suitable for Roberts Stream 202 radio, 9v 1.3a centre positive?** A: Yes the transformer comes with all the different tips needed and a way to reverse the polarity if required just read the instruction carefully and you should be able to find a way to make it work. **Q: Is this an ac to ac adapter or an ac to dc adapter it does not specify in the specs** A: Hi, this is ac to DC. ## Frequently Bought Together - MEROM 9V 2A Power Adapter Supply with 8 Tips and Polarity Reversal Cable Compatible with Arduino Uno REV 3, IEIK UNO R3, Schwinn Proform bike, Crosley Cruiser Portable Turntable Record Player - Arduino Uno REV3 [A000066] – ATmega328P Microcontroller, 16MHz, 14 Digital I/O Pins, 6 Analog Inputs, 32KB Flash, USB Connectivity, Compatible with Arduino IDE for DIY Projects and Prototyping --- ## 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.co.th/products/338824595-merom-9v-2a-power-adapter-supply-with-8-tips-polarity](https://www.desertcart.co.th/products/338824595-merom-9v-2a-power-adapter-supply-with-8-tips-polarity) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-23*
