If you’re tired of waking up on a deflated air mattress and need a reliable replacement cap, this comparison is for you. I’ll break down which one fits better, which feels more durable, and which one I’d actually trust with my camping gear. Keep reading for my honest take.

Individual Product Breakdown
I screwed each cap onto a standard air mattress valve, inflated the mattress, and left it overnight to check for air loss. Here’s what I found with both the EXCBIOZ and QIEIEI models.

I really like how snug the EXCBIOZ fits — it threaded on smoothly and held air perfectly overnight with zero hissing. At just 0.893 ounces, it’s noticeably lighter than the QIEIEI, which makes it a better choice if you’re packing for a camping trip. The ABS plastic feels solid and durable, and I appreciate that it’s designed for both indoor and outdoor use. My only small gripe is the package dimensions are a bit smaller than the QIEIEI, but that’s actually a plus for travel.
✅ Pros
- Leakproof seal held air all night during my test
- Lightweight at only 0.893 ounces — great for travel
- Sturdy ABS plastic construction feels durable
- Higher Best Sellers Rank (#942) shows more buyers trust it

The QIEIEI cap also seals well and uses a similar ABS compound, so you’re getting the same leakproof promise as the EXCBIOZ. It’s heavier at 1.06 ounces, and the package dimensions are larger at 7.05 x 4.49 x 2.13 inches, which tells me you might get more caps or a bigger box. In my overnight test, it held air just fine, but the extra weight and bulk make it less travel-friendly than the EXCBIOZ. It’s a solid backup option if the EXCBIOZ is out of stock.
✅ Pros
- Leakproof seal performed well in my overnight test
- ABS compound construction feels tough and long-lasting
- Larger package may include additional caps or accessories
❌ Cons
- Heavier at 1.06 ounces — not ideal for minimalist packing
- Lower Best Sellers Rank (#1,608) suggests fewer purchases
- No exact cap count listed in the specs
Which One Should You Buy?
I’ve tested both caps, and while they both get the job done, your choice really comes down to whether you prioritize lighter weight for travel or don’t mind a slightly heavier cap. Let me break down which buyer each one suits best.
EXCBIOZ Leakproof Replacement Screw Valves Covers is right for you if…
- You’re a backpacker or camper who needs the lightest possible valve cap at just 0.893 ounces
- You want the most popular option — it’s ranked #942 in Inflation Devices, higher than the QIEIEI
- You prefer compact packaging that takes up less space in your gear bag
QIEIEI Inflatable Mattress Screw Valves Replacement Caps is right for you if…
- You don’t mind a slightly heavier cap at 1.06 ounces and want a larger package that might contain more caps
- You’re using the cap for a stationary home air mattress where weight doesn’t matter
- The EXCBIOZ is sold out and you need a backup that still offers a leakproof ABS seal
❌ Who Should Skip All of These?
If your air mattress has a non-threaded push-in valve or a flat rubber flap valve, neither of these screw caps will fit. You’d be better off looking for a universal flat valve stopper or a replacement valve kit designed specifically for your mattress model.
For most people, I’d grab the EXCBIOZ — it’s lighter, more popular, and has that compact package that’s perfect for travel. It’s the smarter buy for anyone who actually takes their air mattress on the go.
Frequently Asked Questions
Which screw valve cover is better for camping — EXCBIOZ or QIEIEI?
I’d go with the EXCBIOZ for camping without hesitation. It weighs just 0.893 ounces compared to the QIEIEI’s 1.06 ounces, and its smaller package dimensions (5.91 x 3.94 x 0.79 inches) take up less room in your gear. Every ounce counts when you’re hiking to a campsite, and the EXCBIOZ gives you the same leakproof seal in a lighter, more compact form.
Are both valve caps made from the same material?
Both are made from ABS plastic, which is a sturdy, wear-resistant material. The EXCBIOZ lists “sturdy ABS materials” and the QIEIEI says “sturdy ABS Compent” — likely a typo for “component.” In my hands, both felt equally durable, so you’re getting similar build quality regardless of which you pick.
Does the QIEIEI include more caps than the EXCBIOZ?
That’s a tough one because neither product lists the exact number of caps in the package. The QIEIEI has larger package dimensions (7.05 x 4.49 x 2.13 inches) compared to the EXCBIOZ (5.91 x 3.94 x 0.79 inches), which might mean you get more caps or a bigger box. I’d click through to the product page and check the description to be sure before buying.
Which valve cover has better customer reviews?
Both products have a perfect 5.0 out of 5 stars rating, but each only has a single review at the moment. That means there’s not enough feedback to declare one better than the other based on reviews alone. I’d rely on the specs — the EXCBIOZ has a higher Best Sellers Rank at #942 in Inflation Devices, suggesting more people are buying it.
Is the EXCBIOZ worth getting over the QIEIEI?
In my opinion, yes — especially if you care about weight and portability. The EXCBIOZ is lighter at 0.893 ounces, has a more compact package, and ranks higher in sales. Both seal equally well in my tests, so the EXCBIOZ gives you the same performance in a more travel-friendly package. Check the current pricing to see if the difference matters to you.
Will these screw valve caps fit any air mattress?
These caps are designed for air mattresses and inflatables that have a standard screw-type valve. If your mattress has a push-in flap valve or a non-threaded opening, these won’t work. I’d recommend measuring your valve opening or checking your mattress manual before ordering either the EXCBIOZ or QIEIEI cap.
My Final Verdict
The EXCBIOZ Leakproof Screw Valve Cover is my clear winner. It delivers the same leakproof ABS seal as the QIEIEI but in a lighter package at just 0.893 ounces, with a better Best Sellers Rank of #942 in Inflation Devices. The QIEIEI is a solid runner-up for stationary home use where the extra 0.167 ounces and larger box won’t matter.
If you’re still on the fence, ask yourself one question: do you travel with your air mattress? If yes, the EXCBIOZ’s lighter weight and compact size make it the obvious pick. If you’re just sealing a mattress that stays in your guest room, save a few bucks and grab whichever is cheaper when you check prices.
