CHPOWER X1 Carbon Build Plate Specs: 257 x 257 Fit, Smooth PEO vs Textured PEI, and When This Budget Bambu Spare Makes Sense

July 11, 2026

Budget Bambu build plates only make sense if the specs line up with the way you actually print. That means bed fit first, surface behavior second, and only then whether the lower price is worth trusting as a spare-sheet strategy.

The current smooth + textured 257 mm alternative sits in a very practical lane: one cheaper spare for Bambu owners who want both a smoother presentation-side option and a textured everyday side without buying two separate sheets first.

Short answer

This CHPOWER plate is a budget dual-surface 257 x 257 mm spare for Bambu X1, X1C, P1P, and P1S owners who want one sheet that can cover both nicer-looking undersides and normal textured-PEI daily printing. It makes the most sense when you want one flexible backup sheet more than the cleaner certainty of OEM-only plate buying.

Main specs that matter

257 x 257 mm spring-steel plate for Bambu X1/X1C/P1P/P1S class beds
dual-surface layout pairs a smoother PEO-style finish lane with a textured PEI everyday-grip lane
budget spare-sheet angle makes it a practical one-buy backup for owners who want more flexibility than a single-purpose spare
useful for buyers deciding between nicer-looking undersides on selected parts and a safer textured everyday side without buying two separate spares first
strong downstream comparison anchor against OEM textured plates, double-smooth alternatives, and other aftermarket dual-surface 257 mm sheets

Printer fit and bed-size compatibility

The first real spec is the 257 x 257 mm size. That puts this squarely in the Bambu X1/X1C/P1P/P1S spare-sheet lane, where owners are usually not asking for a specialty effect plate first. They are asking whether a cheaper backup sheet can keep plate rotation simple while still covering most everyday jobs.

That fit matters because spare-sheet buying is often about uptime. A correct-size second plate lets you clear parts, start another job faster, and stop treating one worn or messy sheet like the entire printer depends on it.

What the dual-surface spec actually changes

The stronger part of this listing is the split between a smoother PEO-style side and a textured PEI side. That is the real buying decision here.

Smoother side: better when you want a cleaner bottom look on selected parts instead of the normal textured PEI imprint.
Textured side: better for everyday grip, easier rotation into standard jobs, and lower-stress general use.

That is why this product makes more sense as a budget all-round spare than as a specialty plate. It is trying to cover two normal workflows in one sheet rather than dominate one narrow finish niche.

What it works best with

PLA and PETG owners who want one backup sheet for mixed cosmetic and everyday jobs
P1S and X1C owners building a cheaper spare-plate rotation
buyers comparing aftermarket versatility against OEM single-surface simplicity
shops and makers who would rather keep a second plate ready than stop to clean one sheet constantly

What it is not ideal for

buyers who already know they want only textured everyday behavior and do not care about smoother bottoms
owners who prefer staying fully inside OEM plate buying even when the cost per spare is higher
specialty-material buyers chasing a cold plate, engineering-material plate, or one highly specific coating story

Budget spare strategy versus OEM strategy

This is where the specs become useful. The CHPOWER sheet is not a premium-coating flex. It is a budget spare-sheet play. If the real question is “can one cheaper plate give me enough flexibility to stop babying my only sheet,” then the dual-surface design is the feature that matters most.

If the real question is “what is the safest no-surprises official spare,” OEM textured or OEM smooth lanes still make more sense. But that is a different buyer intent than the one this CHPOWER plate is aimed at.

How it compares conceptually

The nearby alternatives usually split into cleaner lanes:

IdeaFormer Textured PEI Build Plate for Bambu P1S and X1C
3DHUB Double Smooth PEI Build Plate for Bambu Lab Printers
SAHVAIM Double Sided Black PEI Build Plate for Bambu Lab X2D/P2S/X1/X1C/X1E/P1P/P1S/A1
Bambu Lab Textured PEI Plate for P1S and X1C

That matters because CHPOWER is strongest when the reader wants one affordable do-most-things spare, not when they have already decided on a pure textured-only, pure smooth-only, or premium-specialty branch.

Who should buy it

Buy this plate if you want a budget 257 x 257 mm Bambu spare with both a smoother side and a textured side, and you care more about flexible day-to-day ownership than premium-plate branding. It fits the “second sheet first, fancy specialty surface later” mindset very well.

Who should skip it

Skip it if you already know your workflow lives on one surface type only, or if OEM confidence matters more to you than saving money on a spare. Skip it too if you are solving a first-layer problem that really points to cleaning, storage, or material moisture rather than another plate purchase.

Bottom line

The current smooth + textured 257 mm alternative makes sense as a budget dual-surface spare for Bambu X1/X1C/P1P/P1S owners who want one sheet that covers smoother-bottom parts and textured everyday printing without paying for multiple spares first.
