Compare the Ello Pop & Fill Stainless Steel Water Bottle and the Port 30oz Tumbler side by side. Find out which reusable bottle fits your daily hydration habits based on lid design, capacity, and on-the-go features.
Quick answer
Choose the Pop & Fill Stainless Steel Water Bottle if you want quick, one-handed refills and a secure locking lid for active days. Pick the Port 30oz Stainless Steel Tumbler if you prefer a large capacity cup with a built-in carry loop and the flexibility to sip with or without a straw.
Lid design and daily convenience
The biggest difference between these two Ello bottles is how you open and drink from them. The Pop & Fill uses a patented Quick Fill™ push-button lid that pops open for refills without twisting a cap. It also has a locking mechanism to prevent accidental spills in a bag. The Port tumbler uses a leak-proof flip lid with a bendable silicone straw that you can remove if you prefer to sip directly from the lid opening.
Capacity and portability trade-offs
The Port 30oz Tumbler holds a full 30 ounces, making it a solid choice for long workdays or car commutes. It includes a built-in carry loop and an integrated side handle for easy carrying. The Pop & Fill is available in multiple sizes (check options), but its strength is the push-button lid that lets you fill up fast at a sink or water cooler. Neither bottle includes a car cup holder guarantee, so measure before you buy if that matters.
Pop & Fill vs Port Tumbler: trade-offs at a glance
- Refill speed: Pop & Fill’s Quick Fill™ lid pops open for fast refills without twisting. The Port tumbler requires flipping the lid open or removing the straw to fill.
- Drinking style: Pop & Fill uses an internal straw and silicone spout. Port gives you the option to sip through a bendable straw or remove it and drink from the flip lid. If you like having both straw and lid-sipping options, the Port is more flexible.
- Carry and grip: Port includes a built-in carry loop and side handle. Pop & Fill relies on its bottle shape and lid lock for secure transport. For frequent carrying by hand or hooking onto a bag, the Port has the edge.

- Pop & Fill Stainless Steel Water Bottle: Patented Quick Fill™ technology lets you refill without unscrewing a cap, and the push-button lid has a secure locking mechanism. You can open and close the bottle with one hand, which is helpful during workouts, driving, or when your hands are full.
