{"product_id":"the-voltwright-30w-universal-power-adapter","title":"The Voltwright | 30W Adjustable Universal Power Adapter, 3V to 12V DC","description":"\u003cdiv class=\"product-narrative\"\u003e\n\u003cp\u003e\u003cstrong\u003eEvery Drawer Of Dead Electronics Has The Same Missing Part.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe device is fine. The power supply is gone, and the replacement costs more than the device is worth or simply does not exist any more. This adapter is the answer to that drawer: a thirty watt switch-mode supply with seven selectable DC voltages covering three, four point five, five, six, seven point five, nine and twelve volts, a maximum output current of two and a half amps, and nine interchangeable tips covering the barrel sizes that consumer electronics actually use.\u003c\/p\u003e\n\u003cp\u003eThe input side runs from one hundred to two hundred and forty volts AC at fifty or sixty hertz, so the same unit works in the US, Europe and the UK by choosing the appropriate plug variant. Output is delivered through a 5.5 by 2.5 millimetre DC interface on a hundred and fifteen centimetre cable, and the voltage is set manually before connection with the supplied key, so there is no ambiguity about what the device is being fed. A separate five volt two point one amp USB output adds a second job: charging a phone while the adapter powers the device beside it.\u003c\/p\u003e\n\u003cp\u003eProtection covers over-voltage, over-current, short circuit and over-temperature, which are the four failure modes that kill cheap unregulated bricks. The switching topology also keeps no-load consumption very low, so leaving it plugged in does not cost anything meaningful. CE certified, regulated output, and small enough to live in a laptop bag.\u003c\/p\u003e\n\u003cp\u003eSetting it up takes one habit that prevents almost every failure: dial the voltage with the key, check it against the label on the device, and only then plug the adapter into the wall. The nine tips snap onto the barrel and each is marked with its dimensions, so there is no guessing about polarity or diameter. Because the tips are interchangeable rather than fixed, one unit replaces the pile of orphaned single-voltage supplies that accumulates in any house or office, and losing a tip costs less than replacing a whole adapter. Pair it with a small label on the tip that works with each device and the drawer organises itself.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eThe right adapter is the one that already fits, already matches the voltage, and costs less than replacing what it powers.\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/div\u003e\u003chr style=\"margin: 20px 0; border: 0; border-top: 1px solid #eee;\"\u003e\u003cdiv class=\"product-features\"\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul style=\"list-style: none; padding: 0;\"\u003e\n\u003cli style=\"padding: 8px 0; border-bottom: 1px solid #f0f0f0;\"\u003e✦ Thirty watt switch-mode supply with seven selectable DC output voltages from 3V to 12V\u003c\/li\u003e\n\u003cli style=\"padding: 8px 0; border-bottom: 1px solid #f0f0f0;\"\u003e✦ Maximum output current of 2.5 A, compatible with devices drawing 500 mA, 1 A or 1.5 A\u003c\/li\u003e\n\u003cli style=\"padding: 8px 0; border-bottom: 1px solid #f0f0f0;\"\u003e✦ Nine interchangeable adapter tips for the common barrel connector sizes\u003c\/li\u003e\n\u003cli style=\"padding: 8px 0; border-bottom: 1px solid #f0f0f0;\"\u003e✦ Separate 5V 2.1 A USB output for charging a phone or tablet at the same time\u003c\/li\u003e\n\u003cli style=\"padding: 8px 0; border-bottom: 1px solid #f0f0f0;\"\u003e✦ Universal 100-240V AC input with US, EU or UK plug variants\u003c\/li\u003e\n\u003cli style=\"padding: 8px 0; border-bottom: 1px solid #f0f0f0;\"\u003e✦ Protection against over-voltage, over-current, short circuit and over-temperature\u003c\/li\u003e\n\u003cli style=\"padding: 8px 0; border-bottom: 1px solid #f0f0f0;\"\u003e✦ 115 cm output cable with a 5.5 mm by 2.5 mm DC interface and voltage selector key\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\u003chr style=\"margin: 20px 0; border: 0; border-top: 1px solid #eee;\"\u003e\u003cdiv class=\"product-specs\"\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul style=\"list-style: none; padding: 0;\"\u003e\n\u003cli style=\"padding: 8px 0; border-bottom: 1px solid #eee;\"\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e 30W, RRZC\u003c\/li\u003e\n\u003cli style=\"padding: 8px 0; border-bottom: 1px solid #eee;\"\u003e\n\u003cstrong\u003eOutput power:\u003c\/strong\u003e 30 W maximum\u003c\/li\u003e\n\u003cli style=\"padding: 8px 0; border-bottom: 1px solid #eee;\"\u003e\n\u003cstrong\u003eInput:\u003c\/strong\u003e 100-240V AC, 0.3 A, 50\/60 Hz\u003c\/li\u003e\n\u003cli style=\"padding: 8px 0; border-bottom: 1px solid #eee;\"\u003e\n\u003cstrong\u003eOutput voltages:\u003c\/strong\u003e 3V, 4.5V, 5V, 6V, 7.5V, 9V, 12V, manual selection\u003c\/li\u003e\n\u003cli style=\"padding: 8px 0; border-bottom: 1px solid #eee;\"\u003e\n\u003cstrong\u003eOutput current:\u003c\/strong\u003e 2.5 A maximum, compatible with 500 mA, 1 A and 1.5 A devices\u003c\/li\u003e\n\u003cli style=\"padding: 8px 0; border-bottom: 1px solid #eee;\"\u003e\n\u003cstrong\u003eUSB output:\u003c\/strong\u003e 5V at 2.1 A maximum\u003c\/li\u003e\n\u003cli style=\"padding: 8px 0; border-bottom: 1px solid #eee;\"\u003e\n\u003cstrong\u003eDC interface:\u003c\/strong\u003e 5.5 mm x 2.5 mm\u003c\/li\u003e\n\u003cli style=\"padding: 8px 0; border-bottom: 1px solid #eee;\"\u003e\n\u003cstrong\u003eIncluded tips:\u003c\/strong\u003e Nine changeable adapter tips\u003c\/li\u003e\n\u003cli style=\"padding: 8px 0; border-bottom: 1px solid #eee;\"\u003e\n\u003cstrong\u003ePlug options:\u003c\/strong\u003e US, EU or UK\u003c\/li\u003e\n\u003cli style=\"padding: 8px 0; border-bottom: 1px solid #eee;\"\u003e\n\u003cstrong\u003eCable length:\u003c\/strong\u003e 115 cm\u003c\/li\u003e\n\u003cli style=\"padding: 8px 0; border-bottom: 1px solid #eee;\"\u003e\n\u003cstrong\u003eProtection:\u003c\/strong\u003e Over-voltage, over-current, short circuit, over-temperature\u003c\/li\u003e\n\u003cli style=\"padding: 8px 0; border-bottom: 1px solid #eee;\"\u003e\n\u003cstrong\u003eCertification:\u003c\/strong\u003e CE\u003c\/li\u003e\n\u003cli style=\"padding: 8px 0; border-bottom: 1px solid #eee;\"\u003e\n\u003cstrong\u003eColour:\u003c\/strong\u003e Black\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\u003chr style=\"margin: 20px 0; border: 0; border-top: 1px solid #eee;\"\u003e\u003cdiv class=\"product-applications\"\u003e\n\u003ch3\u003eWhere It Belongs\u003c\/h3\u003e\n\u003cp\u003eThis is the adapter for a router that lost its supply, a speaker or monitor being repurposed, a security camera in a back office, an LED strip in a display case, a digital piano or keyboard, an effect pedal board, or any of the small household electronics that take a DC barrel input.
