The replacement brick and cord Magcubic makes for its HY300 Pro family, so a lost or frayed charger costs one evening's film, not the whole projector.
The HY300 Pro family runs from an external power supply rather than a board inside the body. That keeps heat out of the small swivel cylinder, but it also means the whole projector depends on one black brick and one metre of cord. Lose it in a move, leave it at a holiday rental, or let the dog chew the cable, and the projector goes dark.
This Magcubic HY300 Pro Power Adapter is the maker's own replacement for that brick. Magcubic names five projectors it is built for:
Input is 100–240 V at 50 or 60 Hz, so the same supply works from a wall socket in the US, the UK or most of Europe with only a plug adapter. The rated output is 36 V at 0.95 A, with a 12 V 0.7 A rating also marked. At 36 V that works out to roughly 34 W of headroom, well above what a small LED projector and its speaker draw during a film.
The housing mixes metal and plastic, the finish is black, and the kit is one supply with its cord. There is no second plug and no USB port; it does one job.

Before ordering, turn the original supply over and read the small print on its label. The output line is what matters: a voltage, a current and a polarity symbol. If yours reads 36 V and the projector is one of the five named models, this supply is the match.
Magcubic makes a second adapter for its newer range, and in a drawer the pair look almost identical. The split looks like this:
| Your projector | Magcubic adapter to use | Rated output |
|---|---|---|
| HY300 Pro, Pro+, HY300X, HY300 Max, HY300F | This HY300 Pro adapter | 36 V 0.95 A / 12 V 0.7 A |
| HY300 Ultra, HY310, HY310X, HY320F, HY320 Pro | HY300 Ultra adapter | 45 V 0.85 A / 12 V 0.7 A |
| Original HY300, other brands | Neither list names it | Match the old label |
That 9 V gap between the two families is why the Ultra supply and this one are not interchangeable, even though the bricks look alike. Plugging the higher-voltage Ultra brick into a Pro is the mistake to avoid.
Many HY300 Pro clones from other brands share the Magcubic body and may run on the same 36 V supply, but none of them appear on Magcubic's list. For a Chicdaze, Alwtniet or ENUOSUMA projector, compare three things on the old label before buying:
Any mismatch on the first or third point means a different supply. The HY300 accessories guide sorts the other adapters, cases and stands by model.
One metre is a modest cord, and it shapes where the projector can sit. On a nightstand next to a wall socket it is plenty. On a sideboard across the room, or on a floor tripod in the middle of the lounge, the supply needs an extension lead.
A few layouts that work around the short run:
Portable power stations with a normal AC socket also run the projector away from the house, since the supply accepts anything from 100 to 240 V. A plain USB power bank will not, because the projector wants 36 V from this brick, not 5 V from a phone charger.
For travel, the wide input range is the useful part. A projector bought in the US runs in a Spanish holiday flat with nothing more than a two-pin plug adapter, no bulky voltage converter. Pack the supply in the case's mesh pocket so the cord does not kink around the lens.
The HY300 screen size chart shows how far from the wall each picture size needs the projector to sit, which tells you how much cord the room calls for.
When an HY300 Pro refuses to wake, the supply is the cheapest suspect and the quickest to test. A few minutes of checking saves ordering a part that will not fix anything.
If the light is on and the screen stays black, the supply has done its job. Troubleshooting then moves to firmware, the HDMI source and the light engine, all covered in the HY300 not-working fixes.
A second supply also earns its keep as a travel spare. Families who take the projector between a flat and a holiday cottage often leave one brick at each place, which halves the chances of turning up for a film night with no power. Store the spare in the projector case so it never wanders.
Look after the cord and it lasts for years:
Owners of a Magcubic HY300 Ultra or HY310 should skip this one and order the Ultra adapter. With a Pro-family model, the related 2026 HY300 Pro and HY300 Pro+ pages show which body you own.
No. Magcubic lists the HY300 Ultra, HY310 and HY320 models for a separate 45 V adapter; this one is rated 36 V for the Pro family.
Magcubic names the HY300 Pro, HY300 Pro+, HY300X, HY300 Max and HY300F. For other brands, match the output voltage and plug on the old label.
Yes. The input accepts 100–240 V at 50 or 60 Hz, so a simple plug adapter is enough in most countries.
One metre (3.28 ft). For a floor tripod or a garden screening, add an extension lead between the socket and the brick.
Not through this supply. The projector takes a 36 V feed from the brick, while a phone power bank gives 5 V; a power station with an AC socket works.
