Tips and FAQs 1. If your device's DC IN voltage is not in the options, please select the closest one. For example, if you device needs 5.5V, you can choose 5V or 6V. 7.9v you can select 7.5v. 2. 8 DC Tips Spec.: 2.5*0.7mm 3.0*1.1mm 3.5*1.35mm 4.0*1.7mm 4.8*1.7mm 5.5*2.1mm 5.5*2.5mm 3.5mm mono. Please DOUBLE CONFIRM the DC jack dimensions to ensure the compatibility. 3. It is a Center Positive + power supply. Please kindly check what polarity of your device before bidding. You can find the polarity information printed beside the power port. 4. If your device needs a Center Negative - power adapter, please kindly don't forget to buy one Belker Polarity Reversed Cable together. The wrong polarity may cause some damage to your device. 5. For AC to DC Power Adapter, normally, bigger one can be compatible with smaller one. For example, 5v 1a works with 5v 0.5a, 12v 1a works with 12v 0.8a. Conversely, NO. So please use it under 12W. How to use correctly 1. Check the AC adapter's DC output parameters and your device's DC in parameters. Please make sure they can be matched well. 2. Connect the correct adapter tip (8 DC Tips Spec.: 2.5*0.7mm 3.0*1.1mm 3.5*1.35mm 4.0*1.7mm 4.8*1.7mm 5.5*2.1mm 5.5*2.5mm 3.5mm mono.) and make sure that it's firmly attached to the dc input port of your device. 3. Set the right DC output voltage which is corresponding to dc12v dc9v dc7.5v dc6v dc5v dc4.5v dc3v switch position. 4. Connect the adapter to the electrical receptacle and powering your devices. Review: Is this item safe for use with Li-ion batteries? - Excellent product. Good price/value. Works as advertised. Quick delivery. Primarily purchased to replace a lost 12v charger for our old, Li-ion JobSmart flashlight - the Anne Bonny of our flashlight fleet. She's been dropped from ladders, crushed by a tractor, epoxied back into frankenlight form and returned to service several times. It has the older style pin jack type connector. Secondary uses will include powering my Dad's 1974 Sperry Remington SSR-8 calculator to avoid the dreaded green death of leaking batteries. it has a blue-green LED display that rapidly flashes out intermediate results while calculating log and trig functions, just to let you know that it's working on it and will get back to you with an answer before Dexter works it out on his K&E Polyphase Duplex Decitrig. Is this item safe for use with Li-ion batteries? The ad copy and documentation don't explicitly state if it is. As I recharged the flashlight (which had stopped lighting months ago) I kept checking the temperature of both the charger and the flashlight until it was fully charged and noticed no temperature rise, so ... fingers crossed. Review: Just what was needed! - I have a blood pressure monitor that just EATS batteries. It, fortunately, also accepts AC power. However, after just a couple of years, I noticed the wire leading into the jack to the device was breaking and before I could figure out what happened, one side of the dual-wire broke entirely. This, with the multiple plugs available and the multiple settings for output power was just what I needed. Once I was able to see the symbol for the power requirements of the port (TINY printing), I chose this device as a replacement. I wasn't sure which of the two largest ports to use as both seemed to fit. I chose the 2nd largest, fearing the other might be too tight and get stuck in! It worked fine! I'm now able to bypass expensive AAA batteries and can use this elsewhere if needed. The only negative (and that is not worth a decrease in stars) is that the wire is flat 2-part. I feel that if it were round, it would be stronger and last longer. ## Features - This AC/DC adapter can apply to most appliances which the input voltage is between 3V and 12V and the rating power is equal to or less than 12 Watt. - AC Input: 100V 120V-240V 50/60Hz, Output: Multi Voltage DC 3V 4.5V 5V 6V 7.5V 9V 12V 1000mA Max(compatible with less than 1 A, like 100ma 200ma 500ma 800ma amps etc.) - This power supply is with 8 different size adapter plugs which fit for your electronics well and solve your various problems. 8 DC Tips Spec.: 2.5*0.7mm 3.0*1.1mm 3.5*1.35mm 4.0*1.7mm 4.8*1.7mm 5.5*2.1mm 5.5*2.5mm 3.5mm mono. Please DOUBLE CONFIRM the DC jack dimensions to ensure the compatibility. - Important Note: The adapter DC plug polarity is center positive "+".

Only thing that surprised me is the new models are "positive tip" only. This is by far the most common configuration but make sure your device says the inside is positive before using, as weird rare things do exist ## Frequently Bought Together - Belker 12W Universal 3V 4.5V 5V 6V 7.5V 9V 12V AC DC Adapter Power Supply for Household Electronics - Max. 1000mA - Basicvolt Universal AC/DC Adapter Multi-Voltage Regulated Switching Power Supply with 11 Selectable DC Plugs for 3V 4.5V 5V 6V 7.5V 9V 12V Household Electronics 2.0A 24Watt Max --- ## 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.vn/products/130872309-12w-universal-3v-4-5v-5v-6v-7-5v-9v](https://www.desertcart.vn/products/130872309-12w-universal-3v-4-5v-5v-6v-7-5v-9v) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-06-05*
