ROLADA AC adapter 19V

Technical details

A missing or failed monitor power supply can put a working screen out of action. This ROLADA AC adapter is intended as a replacement for listed LG monitors and small TVs that use a 19V supply with the matching DC connector. Its output is DC 19V, 2.53A (48W), input is AC 100–240V, 50/60Hz. The package includes the adapter and a power cable.

The DC jack measures 6.5 × 4.4 mm. It is not compatible with other plug sizes or USB-C, so the voltage and connector both matter when choosing a replacement. The listing also specifies over-voltage, over-current, over-temperature and short-circuit protection. Those protections are useful details, but they don’t make the adapter a universal fit.

Practical compatibility

The compatibility list covers a range of LG monitor families, including selected 24MK and 27MK models, UltraWide UM/UB series, and EA, EN and MP series. It also names some smaller TVs, such as the 22LB4510, 24LF4520 and 24MT47D. These are examples from the stated list, not a reason to assume every LG screen will work with this supply.

Match the exact model number and the original adapter’s rating before buying. For instance, a listed 27MK600M-B is a closer match than an unlisted LG monitor that happens to have a similar screen size. If your original unit specifies a different voltage or has another connector, this adapter isn’t the right choice. It may suit you if your replacement need matches the listed rating, plug size and device model.

Usage tips

Before connecting it, compare the label on the original adapter with the stated 19V output and check that the DC jack fits the device. Keep the supplied power cable with the adapter, then route the cable so it won’t be pulled when you move a monitor or adjust its position. A practical use case is replacing a misplaced supply for a compatible desk monitor without changing the display itself.

Based on the listed specifications, this is a purpose-specific replacement rather than a flexible charger for different electronics. That makes it more relevant when the required connector and output are known, a USB-C supply or an adapter with a different barrel plug is not an alternative here. The description doesn’t give cable length, so there’s no basis for judging how far the screen can sit from an outlet.

Before you decide

Which devices are listed? Selected LG monitors across several named series, plus certain small-size TVs. Use the exact model number rather than screen size alone to assess the match.

What should match the original adapter? The 19V rating and 6.5 × 4.4 mm DC jack. The listing explicitly excludes other plug sizes and USB-C.

What comes in the package? One AC adapter and one power cable. No cable length is specified.

Before buying it

Choose this ROLADA supply when your LG device appears in the compatibility list and its original adapter calls for the stated output and connector. Skip it if the model, voltage or plug size doesn’t match, or if you need USB-C. That check is more useful than choosing by brand or screen size alone.
