Klein Tools 55600 Work Cooler, 17-Quart Lunch Box

Really 4.5/5. I bought this lunchbox over a year ago. I love the capacity and its held up pretty well. Keeps food cold all day and its great to be able to sit on it during lunch break, it's very solid and sturdy. Only negative thing I have to say about it is that the plastic on the bottom has worn down to the insulation layer. It spends all day sliding around on a hot steel shelf in my work truck, so thats not all that surprising. Thicker or tougher plastic/material on the bottom would've been great, but oh well. Hopefully it's something they'll improve in the future.

Klein Tools 55600 Work Cooler ReviewI’ve been using the Klein Tools 55600 Work Cooler on job sites and weekend projects, and it’s become my go-to for keeping drinks and snacks ice-cold all day. In 90°F heat, with two to three large ice packs, it easily maintains a chill for 8–12 hours—more than enough for a full shift outdoors.Key Features• 17-quart capacity holds up to 18 standard cans• Durable roto-molded construction rated to support up to 300 lb• Thick insulation delivers up to 30 hours of cooling under ideal conditions• Tradesman Pro Tough Box design resists dents, dings, and UV damage• Compact enough to stash under a bench or in a truck bedReal-World PerformanceOn hot summer days, I loaded the cooler with 2–3 big gel packs and a dozen canned drinks. Even after 10 hours in direct sun, everything was still frosty. The seal around the lid is snug enough to prevent leaks and prevent ice from melting too quickly, and the heavy-duty latch keeps everything locked in tight.There’s plenty of room for lunch containers, sandwiches, and a few cold salads alongside your beverages. I’ve even tossed in a frozen block of fruit for an afternoon snack that stayed firm until I was ready to eat.Unexpected Bonus: Versatile Work StoolThe top of this cooler is built like a mini workbench—flat, rigid, and easy to stand on. I often use it at home to gain a couple extra inches when reaching high kitchen cabinets or changing lightbulbs. Supporting up to 300 lb without flex makes it more reliable than most folding step stools I’ve owned.Build Quality & ValueFrom the robust hinges to the reinforced handles, every detail feels thoughtfully engineered. The shell has taken knocks on concrete floors and gravel driveways with zero damage, and it’s simple to clean when mud or sawdust accumulates. Considering its performance, I find the price point completely justified—this cooler will outlast cheaper alternatives by years.Final VerdictIf you need a rugged cooler that doubles as a work stool and keeps your refreshments icy in extreme heat, the Klein Tools 55600 is worth every penny. Highly recommend for tradespeople, outdoor enthusiasts, and anyone who values durability and reliable temperature retention.

I bought this for my husband to use as a lunch cooler. I have purchased the usual brands in the past and they either don't keep his food cold all day or the are flimsy and end up coming home with duct tape holding the lid on. And don't get me started on the prices for these pieces of junk with a "name" on them. When I saw this I thought "why not, Klein makes tough tools, why not a cooler". It came pretty quickly and I also ordered the 2 Klein ice packs for the bottom. It is a really sturdy cooler and can actually double as a seat at break time! It has a ton of room inside and a secure compartment in the lid for napkins, utensils, whatever. PERFECT! The first lunch i packed all fit with no squishing and the carry strap works much better than those solid handles that can't be thrown over your shoulder. It has a place for a lock on the lid if you happen to have a snack cake snatched on site and we've all had one of those at one time or another!It kept my husband's lunch cold, his drinks frosty and his brownies safe! This is THE BEST COOLER I have ever purchased and I will never, ever spend too much money on those other brands again! And you shouldn't either! We have taken it to the beach, the lake, fishing trips, you name it and it always performs at 110%.

BUY IT NOW!!! I wanted to surprise my husband by getting him a new lunch bag and this definitely over delivered!! He absolutely loves it!! Keeps his lunch and snacks cool it is very well insulated and durable and he loves that it doubles as a seat! He has thanked me multiple times for this purchase and has even said this is the best lunchbox he’s ever seen. I also love that it has the compartment inside that still allows me to write little love notes and keeps it dry. A great investment for the money you spend it’s well worth it! You will not be disappointed!!

Add a handle and it would be a 10 star cooler!!!!This cooler is great for summertime use in construction. It's bigger than an average lunch box cooler so it holds more drinks. Keeps things nice and cold. Makes a great seat for sitting on without denting the lid (I'm 220lbs). Definitely durable. My only complaint is it doesn't have a handle. That's not a deal-breaker but it makes it harder to get it out of your car. It does have a heavy duty strap. But add a handle and it's the perfect cooler.

Absolutely amazing cooler for the price!For context, I am a FedEx delivery driver. It is hot out, So I purchased this cooler for full intentions to leave it in the step van while I'm at work. So it stays in the van 24/7 because I run the same truck everyday. I needed a cooler to keep in the truck because my little lunchbox just wasn't cutting it anymore. I fill it with water bottles and food/snacks if I need to for the day. I keep 6 bottles of water at all times, and fill it with ice every morning, well, kind of.When I get back for the day, there is still PLENTY of ice, but of course, the back of that van is hot. So for the normal person, this cooler would be great. Mine stays in hot conditions, the ice lasts 18+ hours easily. Which is more than enough for my purposes. I've had it for a couple weeks now, and decided to finally write a review!The other day, I'm driving to my next stop, going out windy tight West Virginia mountain roads going about 40-45mph, trying to be quick, I was like a FedEx Nascar driver (Just kidding lol)...I cut a turn a little sharp and apparently the cooler slid from the back, out to the cab, and out my open side door. It smacked the side of the mountain. I slammed on the brakes and put it in reverse to go back and get it (It's not a busy road) and my drinks and ice were everywhere. I thought for sure the cooler was in pieces, but NOPE! It literally only got a couple scratches on it! I am absolutely thoroughly impressed with the quality of this Klein Cooler!! I now have a carbiner clip on the lock so incase something like this happens again it won't fly open 🤣All in all, the cooler, the ability to lock it, the step stool feature, and the inside storage is a 10/10 for me!!!! Would absolutely recommend this cooler!!

Great cooler if I have it out in direct sunlight it holds ice for a whole day if I have it in my truck it holds ice for two and a half days. Small enough to fit in my tractor but big enough to hold anything I might need I usually keep six bottles of water and Three monsters. I forgot it was on the back of my flatbed and took off with it down the road it fell off while I was going about 20 mph and didn't really damage the cooler a whole lot so it's pretty durable. I've had several different kinds of coolers including igloo, lifetime and Ozark trails but for the price of this cooler and the quality of it I'm placing another order for two of them as gifts. I might even buy the bigger version just to keep on my truck but so far this one has held up and has been my longest lasting cooler

I've been using Klein electrical tools for years so when I needed a new lunch cooler for work sites, figured I'd stick with what I know. This thing is built exactly like you'd expect from Klein - tough as nails and designed by people who actually work for a living.The 17-quart size is perfect for a full day on the job. Fits my lunch, drinks, snacks, and still has room for ice packs. Not so big that it's a pain to carry but plenty of space for everything I need during a 10-hour shift.Insulation is legit - my drinks stay cold all day even sitting in a hot truck or out in the sun. Ice packs are still partially frozen when I get home which never happened with my old cooler. Makes a huge difference when you're working outside in summer.Build quality is what you'd expect from Klein. Heavy duty construction that can handle being tossed around job sites, dropped off tailgates, and generally abused. The latches are solid and the hinges feel like they'll last forever.The handle is comfortable and doesn't dig into your hand when it's loaded up. Shoulder strap is a nice touch too for when you're carrying other gear and need your hands free.Fits perfectly behind the seat of my truck and doesn't slide around while driving. Size is just right for most work vehicles without taking up too much space.Easy to clean out at the end of the week - just hose it down and it's ready to go. No weird corners or crevices where stuff gets stuck and starts smelling funky.Price is fair for Klein quality. Yeah you can get cheaper coolers but they'll fall apart in six months. This feels like it'll last as long as my Klein pliers and screwdrivers.Perfect work cooler that actually keeps up with the demands of real job sites. Finally don't have to worry about warm drinks and soggy sandwiches.

I was looking for a decent esky as a tradie who is also on the road all day.Turns out I had to look to the US - and this is one solid unit. Best esky I have used, fits drinks and food and cutlery and more, and keeps it all cool, and doubles as a decent seat.Doesn’t hold a slab but 18 cans is close enough.

My boyfriend absolutely loves this lunch box. He can fit his lunch plus a 2L water bottle without any problem, and it still closes easily. It’s also very sturdy—he can comfortably sit on it during his breaks. Great quality and very practical! A little big but worth it

Buen diseño, calidad en sus plasticos, color perfecto para lugares de trabajo

Getestet und für eien drei Tagestrip super

Would prefer a soild lifting handle instead of strap
