Universal 90W adapter with 15 tips

The GreBed BRJ90190474 is a 90W universal AC adapter that ships with fifteen interchangeable barrel tips. It targets owners of HP, Dell, ASUS, Acer, Samsung, Sony, Fujitsu, Lenovo and Gateway laptops who need a single replacement charger. The unit accepts 100-240V AC input at 50-60Hz for worldwide use.

Output fixed at 20V 4.74A max

The adapter delivers a maximum of 90W at 20V 4.74A, with selectable output voltages between 18.5V and 20V. A smart chip adjusts voltage automatically, but the device cannot supply more than 90W. Laptops that require higher wattage or a different fixed voltage will not operate correctly with this unit.

Match tip from fifteen supplied

Installation consists of choosing the correct tip from the fifteen provided, such as the 4.8x1.7mm M4, 5.5x2.5mm M5, 5.0x3.0mm M6, 6.5x4.4mm M8 or 11.0x5.0mm M10, and plugging it into the barrel connector. The most common issue is selecting a tip that fits physically but does not match the laptop's required voltage or polarity.

Questions about this item

Which of the 15 included tips should I select for my laptop?

Match the tip to your device using the listed compatibility: M4 fits HP Pavilion and Compaq Presario models, M5 fits Asus, Lenovo IdeaPad, Toshiba Satellite and some monitors, M6 fits Samsung and ATIV Book models, M8 fits Sony VAIO and Fujitsu, M10 fits Lenovo ThinkPad X1 Carbon and Yoga series.

What does the 90W rating mean when the adapter is powering my notebook?

It is the maximum power the unit can deliver; the smart chip will automatically select 18.5–20V up to 4.74A so your laptop draws only what it needs, provided its requirement does not exceed 90W.

What input voltage range does the barrel connector accept and what does that cap in practice?

The adapter accepts 100–240V AC at 50–60Hz worldwide, and its output is capped at 90W (20V 4.74A) regardless of the input voltage used.
