Review: problem was between charger and adapter ... (human error) - Unfortunately we lost the charger to our Midland GXT1000VP4 36-Mile 50-Channel FRS/GMRS Two-Way Radios so on the hunt i went on desertcart and found this charger. When i plugged it in nothing... i thought i bought a dud or the wrong thing but realized the problem was between charger and adapter ... (human error). I needed to turn the voltage dail. DUH 🙄 once I did that it worked like a charm!!! Two way radios should be all charged up for first RV trip of our camping season. One suggestion i would recommend is a way to attachh the little key to the cord. Like a small hole that a little twist tie can go through because i fear i will lose it. However i think any flat head screw driver or the side of a peeny may work if lost... like i said, just a suggestion. Overall very please to have chosen this item as i think will now try to see what else i have that the other sized ports will work with around my house. ## Features - 12W Power Supply Spec.: Input: AC 100-240V, 50-60Hz, DC output: 3V, 4.5V, 5V, 6V, 7.5V, 9V, or 12V 1.2A(1200mA Max), ✔️ Only for 3V-12V DC ≤1.2A Devices; Use the included key tool to securely dial in your required DC output; Warning: You must lock in the correct voltage before plugging the adapter into your device to prevent functional failure or damage; - ⚡ NOT UNIVERSAL: This adapter provides a maximum output of 12W and 1.2A (1200mA). It works perfectly for devices requiring less than 1.2A (e.g., 500mA, 1A). ❌NOT COMPATIBLE with high-draw appliances requiring 2A, 3A, or higher (such as percussion massagers, cordless vacuums, or large Yamaha keyboards) 🛑 NOT A BATTERY CHARGER: This is an AC to DC power supply adapter. It will NOT charge batteries for cordless vacuums, rechargeable flashlights, or hover-boards - 🔌 8 INTERCHANGEABLE TIPS (MEASURE FOR FIT): Includes 8 different right-angle connector plugs: 5.5*2.5mm, 4.8*1.7mm, 4.0*1.7mm, 3.5*1.35mm, 3.0*1.1mm, 2.5*0.7mm, 3.5mm Mono, and 5.0*2.1mm. ✅Crucial Step: Please measure the inner and outer diameter of your device's input port to ensure a secure physical fit. (Note: Not compatible with USB-C or Micro-USB ports) - ⚠️ CRITICAL: CHECK DEVICE POLARITY BEFORE BUYING: This adapter is Center Positive (+) ONLY and the polarity is NOT reversible.🚫 Many devices (like electronic keyboards and guitar pedals) require a Center Negative (-) power supply. Using this adapter on a Center Negative device will not work and may cause damage. Please locate the polarity symbol on your device before purchasing - ✅ SPACE-SAVING REPLACEMENT & SUPPORT: Replaces a drawer full of cords for low-power household electronics like LED light strips, wireless routers, electronic scales, and small fans. Backed by a 12-Month Warranty and 30-day return policy. Troubleshooting: If it fails to power your item, double-check that your device is Center Positive (+), requires 1.2A or less, and that the tip fits snugly - 🔧 TROUBLESHOOTING GUIDE: If your device is not powering on, please verify the following: 1. Voltage: Is the dial locked to the exact DC output required by your device? 2. Polarity: Is your device strictly Center Positive (+)? (It will not work with center negative devices). 3. Amperage: Does your device require more than 1.2A? (If it requires 2A, 3A, etc., this 12W adapter is not powerful enough to run it) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01ISM267G | | Additional Features | AC DC, Short Circuit Protection, Universal | | Amperage | 1.2 Amps | | Brand | SoulBay | | Built-In Media | 1pc Universal AC/DC Adapter, 8pcs Adapter Tips | | Color | Black | | Compatible Devices | AC-DC Converters, Game Consoles, Keyboards, Router, Piano, LED strip light, CCTV Camera, Cable Modem, TV Box, Arduino project, CD player, Scale, Clock, Baby Monitor, Small Fan, BP Monitor, POS Machine and most 3V-12V electronics, Speakers Compatible Devices AC-DC Converters, Game Consoles, Keyboards, Router, Piano, LED strip light, CCTV Camera, Cable Modem, TV Box, Arduino project, CD player, Scale, Clock, Baby Monitor, Small Fan, BP Monitor, POS Machine and most 3V-12V electronics, Speakers See more | | Compatible Power Plug Type | Type A - 2 pin (North American) | | Connectivity Technology | Barrel Connector | | Connector Type | Barrel Connector | | Current | AC/DC | | Current Rating | 1200 Milliamps | | Customer Package Type | FFP | | Customer Reviews | 4.1 out of 5 stars 8,118 Reviews | | Enclosure Material | Plastic | | External Testing Certification | Não Aplicável | | Form Factor | Boxy/Brick-like | | Frequency Range | 50-60Hz | | Included Components | 1pc Universal AC/DC Adapter, 8pcs Adapter Tips | | Input Voltage | 120 Volts (AC) | | Item Weight | 3.04 ounces | | Main Power Connector Type | 2 Pin | | Manufacturer | SoulBay | | Mfr Part Number | UC02U | | Model Number | UC02U | | Mounting Type | Wall Mount | | Number of Items | 1 | | Number of Power Levels | 8 | | Output Current | 1200 Milliamps | | Output Voltage | 12 Volts (DC) | | Portable | Yes | | Power Plug | Type A - 2 pin (North American & Japanese) | | Power Source | Corded Electric | | Special Feature | AC DC, Short Circuit Protection, Universal | | Specification Met | CE, FCC, IEC | | UPC | 712809492138 600984723553 | | Unit Count | 8.0 Count | | Wattage | 12 watts | | Wired Charging Connector Type | USB Type A | ## Product Details - **Amperage:** 1.2 Amps - **Brand:** SoulBay - **Color:** Black - **Connector Type:** Barrel Connector - **Included Components:** 1pc Universal AC/DC Adapter, 8pcs Adapter Tips - **Input Voltage:** 120 Volts (AC) - **Number of Items:** 1 - **Special Feature:** AC DC, Short Circuit Protection, Universal - **Wattage:** 12 watts ## Images ![SoulBay 12W Universal Multi Voltage AC/DC Adapter Switching Power Supply with 8 Selectable Adapter Plugs, Suitable for 3 V to 12 V Device - Image 1](https://m.media-amazon.com/images/I/71iY1iFzW+L.jpg) ![SoulBay 12W Universal Multi Voltage AC/DC Adapter Switching Power Supply with 8 Selectable Adapter Plugs, Suitable for 3 V to 12 V Device - Image 2](https://m.media-amazon.com/images/I/81Y2dsDG7vL.jpg) ![SoulBay 12W Universal Multi Voltage AC/DC Adapter Switching Power Supply with 8 Selectable Adapter Plugs, Suitable for 3 V to 12 V Device - Image 3](https://m.media-amazon.com/images/I/61YVqSSIzsL.jpg) ![SoulBay 12W Universal Multi Voltage AC/DC Adapter Switching Power Supply with 8 Selectable Adapter Plugs, Suitable for 3 V to 12 V Device - Image 4](https://m.media-amazon.com/images/I/61LTf9JTECS.jpg) ![SoulBay 12W Universal Multi Voltage AC/DC Adapter Switching Power Supply with 8 Selectable Adapter Plugs, Suitable for 3 V to 12 V Device - Image 5](https://m.media-amazon.com/images/I/61CMr-YfcpS.jpg) ## Questions & Answers **Q: I have a 4 ft Gemmy indoor inflatable football player that needs a 12 watt charger. Anyone know if this will work?** A: Not 100% sure. List three points to help you distinguish if it's compatible...1.Polarity: inner positive2.Meet the working requirement of 12W charger, be aware that the maximum current is 1.2Amps. (If needed current exceeded 1.2A, please search: SoulBay 30W Charger.)3.Find the suitable adapter plug,6 Connection Tips Spec.: 2.5*0.7mm, 3.0*1.1mm, 3.5*1.35mm, 4.0*1.7mm, 5.0*2.1mm, 5.5*2.5mmBesides, Should you have the detailed sticker of your original adapter, please keep free to contact us at aruiservice@hotmail.comHope this helps you and best wishes! **Q: i am looking for an adapter which would output 12v at .5A. Can this adapter do that?** A: Hello Leno,Yes, it can. FYA, find a suitable adapter plugs for your device.Hope this helps you, have a nice day! **Q: I have no idea what "inner positive" means, so how does one know if they have a device that is inner positive? all the connection says is 4.5v dc....** A: This can be tricky in some instance.. This unit has a (+) positive inner, and a (-) negative outside. Which means the female of the plug is positive, and the male ( outer metal) is negative. Now tricky part, some devices use outer ( positive "+") and (negative" -" ) inner. I ran into this with some light, and score board. I bought generic transformer on Amazon, and none worked. took apart light , and found the polarity was reversed. This is how OEM folks fool conservatives that don't buy OEM parts, or know how electricity works in dc circuits. (Had me confused for an hour or two) OEM= Original Equipment Mfg. **Q: When using the 12 volt setting, what are the amps?** A: I haven't used or tested the 12 Volt setting. However excluding losses a IxV=W, so we can substitute and get I=W/V which in this case would be I=12/12, so theoretically the maximum current at 12 Volts would be 1 Amp. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Woks wonderfully *by M***1 on January 28, 2026* Love it !!!

Overall very please to have chosen this item as i think will now try to see what else i have that the other sized ports will work with around my house. ### ⭐⭐⭐⭐ Works on some devices ..... not others *by B***T on August 16, 2019* We did some interior remodeling of the house and lost the AC plus to the OttLite Model T3 LED 5W 5V 1A. This looked like the solution. The first unit came with a RadioShack AC plug no orange colored voltage adjuster. Returned and prompt replacement (no charges). Easy to use. Key to adjust voltage, OK lots of plugs. Found one that seemed to fit, but the OttLight would not turn on. Sometimes there was electricity and the light would flicker but for the most part it didn't work. Other plugs would not fit, either too small or to big. So as a test I connected the adapter to a Tripp-Lite UBS hub (5V 4A) and it worked fine. Both the OttLite and TRIPP-Lite have the same (+) polarity. Make sure the clarity of what you have is correct. Also make sure the green light on the AC block is green, I had an extension cord that I plugged into and it didn't work because of a bad connection. Of note the plugs for the device have one pin that is thicker than the other so be aware and not push too hard, the size difference is not so apparent. The other aspect, which may or not be an important factor is that the lugs to the device are a 90 degree angle. Overall- it didn't work for my main purpose (OttLite) but can work (USB Hub test). Easy to use. Good value for money if it works. ## Frequently Bought Together - SoulBay 12W Universal Multi Voltage AC/DC Adapter Switching Power Supply with 8 Selectable Adapter Plugs, Suitable for 3 V to 12 V Device - SoulBay 12V Power Supply Universal AC DC Adapter Charger with Adjustable Output 5V 9V 3V 6V 4.5V 7.5V 12 Volt 1A 1.5A 2A for LED Strip Light CCTV Camera BT Speaker GPS Webcam Router, 5 FT Cord, 30W - SHNITPWR 3V ~ 24V 3A 72W Power Supply Adjustable DC 3V 5V 6V 9V 12V 15V 16V 18V 19V 20V 24V Variable Universal AC/DC Adapter 100V-240V AC to DC Converter with 14 Tips 5.5x2.5mm 4.0x1.7mm 3.5x1.35mm --- ## 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/32407305-soulbay-12w-universal-multi-voltage-ac-dc-adapter-switching-power](https://www.desertcart.tn/products/32407305-soulbay-12w-universal-multi-voltage-ac-dc-adapter-switching-power) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-04*
