Start with the powder label, not the container
A small protein container is a place to carry an amount already measured for your intended use. It is not a substitute for the directions on the powder package. Keep those directions available after you decant the powder, and retain its identity so two similar-looking powders are not confused. This guide does not choose a dose or recommend taking a supplement.
For this PEHADU option, the seller states 50 ml for each container. Milliliters describe volume; grams describe mass. Powders can occupy different volumes at the same mass because their composition and packing differ. A more tightly settled portion may also occupy a different space from a loosely filled one. There is no product-specific density evidence here that turns the capacity into a fixed number of grams or scoops.
Why the 20 g image does not settle the question
One supplied promotional image says the container can hold 20 grams of powder. It does not identify the powder, its density, or the filling conditions. We therefore retain that claim as a source limitation rather than a universal capacity promise. Do not use it to infer that every protein powder container holds the same mass, or that 50 ml means 50 g.
The distinction is useful before purchasing: determine the volume occupied by your intended, separately measured portion rather than reverse-engineering a serving from the accessory. If you cannot compare the portion with the usable chamber or check it without a return-risk concern, ask the seller for usable capacity information. A nominal volume alone cannot answer whether your specific portion fits.
| Source statement | Useful interpretation | Unsupported shortcut |
|---|---|---|
| 50 ml per container | Seller-stated volume for this option | 50 g, a fixed scoop count, or a fill-to-line dose |
| 2 Pack | Two separate containers in the title | One chamber with 100 ml usable capacity |
| 20 g image text | Unspecified promotional example | A mass guarantee for every powder |
Make a fit decision without compressing the powder
When assessing a funnel for protein powder, compare your measured amount with the chamber and leave the cover seating area clear. A cover that needs pressure to close is a reason to use a different container arrangement, not a cue to compress powder into the cap threads. No calibrated fill line, scoop volume, or closure-clearance specification was supplied for this kit.
Keep separate containers distinguishable if they hold different powders or portions, and keep the original labeling accessible. Two units provide two separate carrying spaces; they do not automatically make one large portion practical. Do not transfer a mixing or dosing assumption from a different 100 ml variant to this 50 ml listing.
Know when this kit is not the right size
If your intended amount does not fit without crowding the closure, choose an appropriately sized container rather than changing the amount to suit the accessory. This kit is described for dry powder and does not establish storage life, moisture protection, or suitability for liquid. Capacity is only the first decision; the next is whether the powder can be transferred into your actual bottle.
