Devoko 30-Gallon Resin Deck Box Review
As an Amazon Associate we earn from qualifying purchases. Details
The Devoko 30-gallon deck box is a black resin storage box that the listing gives as 30 gallons, or 113.56 liters, with a 220-pound seat rating. It suits outdoor storage of cushions, pool toys and garden tools on a patio or deck, provided its footprint, lid and lock match your space. This review is built from the listing text and two CPSC notices on storage chest lids.
Quick answer
- The listing gives a 30-gallon capacity, a 22 by 16 inch interior and an 8.8-pound empty weight. These figures fit a patio or deck where a light, lockable box is the goal.
- The listing contradicts itself on two points: the interior height (20 inches in a bullet, 21 inches in a specification field) and the lid type (flip top in one field, lift-off lid in another). Check both on the product page before you buy.
- The 220-pound figure is a seat rating in the listing. The listing does not say whether the lid is built for sitting, so do not sit on the lid unless the product page confirms it.
- Two CPSC notices show why the lid and lock matter for any storage chest with a hinged lid, especially around children.
The listing at a glance
The table gives only what the listing states. Where a field is missing or conflicts with another field, the cell says so.
| Field | What the listing states |
|---|---|
| Brand and model | Devoko, model 250063BK, black |
| Material | Polypropylene resin, described as durable and weather-resistant |
| Capacity | 30 gallons, or 113.56 liters (specification field and bullet) |
| Interior size | 22 by 16 inches; height is 20 inches in a bullet and 21 inches in a specification field |
| Item weight | 8.8 pounds |
| Maximum weight | 220 pounds, described as a seat rating in a bullet |
| Water and UV | Waterproof and UV resistant, per the listing; no test standard or time frame is given |
| Lock | Described as lockable; the listing does not say whether a lock is included |
| Lid | Flip top in one field; lift-off lid in another; a raised rim of about 1 inch that the bullet describes as smooth |
| Assembly | Six side panels; the listing says about five minutes |
Check the height first: the two figures
The listing gives two interior heights. The bullet says 20 inches, and the specification field says 21 inches. The two figures are not a rounding difference, because they change the volume. The arithmetic below lets you see which one fits the listed 30 gallons.
Volume in cubic inches is length times width times height. One US gallon is 231 cubic inches. The formula with the 22 by 16 inch interior gives:
- At 20 inches: 22 x 16 x 20 = 7,040 cubic inches, which is 30.5 gallons or about 115.4 liters.
- At 21 inches: 22 x 16 x 21 = 7,392 cubic inches, which is 32.0 gallons or about 121.1 liters.
- The listed figure is 30 gallons, or 113.56 liters.
The 20-inch height is closer to the listed capacity, by about 1.8 liters, against about 7.5 liters for 21 inches. That does not prove the interior height, because wall thickness, the lid and the rim all change the internal space and the listing does not give them. It does show that the 20-inch bullet is the more consistent figure for the capacity, and that the 21-inch specification should be confirmed on the product page before you plan a tight fit.
Worked example: footprint and lift
The footprint is the interior length times width, which gives 22 x 16 = 352 square inches, or 352 divided by 144 = 2.44 square feet. That is the space the box occupies on the deck, not counting the lid opening. Add room in front for the lid to open fully, and check that the lid can clear a wall, a table or a rail. The listing does not give an opening arc or the lid’s open height.
The empty box weighs 8.8 pounds, so one person can move it. Once it is loaded, the weight rises by whatever you put inside, and the listing gives no load rating for the floor or the lid other than the 220-pound figure described as a seat rating.
The seat rating: what the listing does and does not say
A bullet says the box can be used as an extra seat with a maximum load capacity of 220 pounds, and that its height and rounded lid make it comfortable to sit on. Read that bullet as the manufacturer’s claim. The listing does not say whether the 220 pounds applies to the lid, the lid hinge, the side panels or the base, and it does not say the box is designed to be sat on repeatedly. The 220-pound figure is also described as a maximum recommendation in the specification field, which is a different wording from a load test.
If you plan to use the box as a seat, check the product page for whether the lid is rated for it, and place the box on a level, firm surface. The listing does not say whether the box should be raised off a wet deck or patio, so that point is also not covered here.
Lid, lock and child safety
The lid is the part of a storage box that most often creates a hazard for children, which is why this section draws on CPSC notices. A CPSC warning issued on March 5, 2014 says that lids on many storage chests and trunks can latch automatically, which can lock a child inside. It also says that the lid supports on older chests can fail to hold the lid open, so the lid can drop suddenly. For chests that have an automatic latch and were not recalled, the advice in that notice is to disable or remove the lock.
A second CPSC notice, dated October 11, 2001, describes the voluntary standard for toy chests as requiring hinged lids to have supports that keep the lid from falling onto a child’s head. This Devoko box is a deck box, not a toy chest, and the listing does not say whether it meets that standard or any other. The notice is included to show what to look for, not to say the box is compliant.
In practice, check three things on the product page: whether the lid stays open on its own in any position, whether the lock can latch the lid shut from outside, and whether the lock can be removed or disabled if it is included. If the lid can drop or lock shut, do not leave a child alone near the box.
Outdoor use: water, UV and the ground
The listing describes the resin as waterproof and UV resistant, and it calls the box a weather-resistant storage option for a patio or deck. Neither claim includes a test standard, a rated time frame or a warranty period in the fields the listing gives. The phrase waterproof describes the box, not the lid seal, so keep cushions and damp items in a ventilated spot if the box stays closed for long periods. That is a general storage habit, not a listing requirement.
Product
1. Devoko 30-Gallon Resin Deck Box, Black (ASIN B0BRX7K8LZ)
Why it is in the set: it is the one deck box that the research for this keyword found, with a 30-gallon capacity, an 8.8-pound empty weight and a lockable resin body. Its listed figures are consistent with a deck box that one person can move and place.
Skip if: you need more than 30 gallons, you must sit on the lid regularly, or the lid needs to stay open in every position without a support you can verify.
One limit: the listing gives both a flip-top and a lift-off lid, and both a 20-inch and a 21-inch height, so confirm the lid type and the height before you buy.
Fit checklist before you buy
- Measure the space on the deck or patio, and add the lid opening to the footprint of 22 by 16 inches.
- Confirm the lid type and whether it opens toward a wall, a chair or a rail.
- Confirm the interior height on the product page, using the 20-inch and 21-inch figures in the listing.
- Check whether a lock is included, and whether the lock can be removed.
- Confirm whether the lid is rated for sitting before using the box as a seat.
- Assemble the six side panels as the listing describes, and check every panel is secure before you load the box.
Mistakes to avoid
- Treating the 220-pound figure as a lid rating. The listing gives it as a seat rating, and does not say the lid is built for sitting.
- Trusting one height figure. The bullet and the specification disagree by one inch, and the one-inch difference changes the volume by about 7 liters.
- Assuming the lock is included. The listing says the box is lockable and does not say whether a lock comes with it.
- Leaving a lid that can latch shut within reach of children. The 2014 CPSC notice covers storage chests that latch automatically.
- Buying for hose storage. The listing describes cushions, pool items and garden tools, not hoses, so a hose reel suits that job better.
How we chose
The research for this keyword held one deck box listing, and it is the product reviewed here. The criteria were the figures the listing states: capacity, interior size, weight, the stated seat rating, and the closure and lock wording. A Walmart page for the same name was opened, but it showed a verification check and no product details, so it is not cited. We did not seek out a second brand, because the keyword is about this model. The listing is the main source, and the two CPSC notices are relied on only for the lid and lock points.
What we could not verify
- The lock: whether one is included, and whether the lid latches automatically.
- The lid type: whether it is a flip top, a lift-off lid, or a lid that does both, since the listing gives both descriptions.
- The interior height: whether the bullet or the specification is right.
- Whether the 220-pound figure applies to the lid. The listing gives it as a seat rating without a load-test description.
- Whether the box is waterproof in a sealed sense, or how long the UV resistance lasts. No test standard or time frame is given.
- Whether the box should be raised off the ground. The listing does not say.
- A manufacturer page for the box. A search for one returned retailer pages only, so the listing is the only product source.
- The recommended-use field. The specification lists it as arts and crafts, which does not match a deck box, so treat that field as a listing error.
- The live listing text. When the product page was opened on 2026-10-21, the specification section was not reached, so the field values above come from the listing record dated 2026-10-12.
FAQ
How much can the box hold?
The listing gives a capacity of 30 gallons, or 113.56 liters. The interior arithmetic in this review supports the 20-inch height more closely than 21 inches, but the product page should confirm the interior.
Can I sit on it?
The listing says the box can be used as a seat with a maximum load of 220 pounds. It does not say whether the lid is rated for that, so check the product page before you sit on the lid.
Is it waterproof?
The listing describes the resin as waterproof and UV resistant. It gives no test standard or time frame for either claim.
Does it lock?
The listing says the box is lockable. It does not say whether a lock is included, so confirm that on the product page.
Is a deck box safe for children to be near?
The main risk with a storage chest is the lid. CPSC has warned that some storage chests latch automatically and that older lid supports can fail. Check that the lid stays open in every position, and that a lock can be removed or disabled, before children are around the box.

Bottom line
The Devoko box is a 30-gallon, lockable resin box with an 8.8-pound empty weight and a listed seat rating of 220 pounds. Before you buy, confirm the interior height, the lid type, whether a lock is included, and whether the lid is rated for sitting. Those four points decide whether the box fits and whether it is safe to leave open near children.
