Cooler Shock Reusable Ice Packs for Cooler - Long Lasting Cold Freezer Packs for Coolers and Lunch Boxes - Cooler Ice Packs for Camping Gear, Fishing, Road Trips, Beach Must Haves

Rating: ⭐⭐⭐⭐⭐ (5/5) I purchased the Cooler Shock Reusable Ice Packs with my own money, and my review was not solicited. These ice packs have proven to be a game-changer for keeping my cooler contents chilled and eliminating the hassle of leaky ‘blue ice’ blocks. The quality of these ice packs is top-notch. Though they require a simple assembly, the package includes everything needed, such as a funnel, rubber stoppers, and caps, to make the process effortless. Once assembled, they freeze solid overnight, ensuring optimal cooling performance throughout the day. What impressed me the most is how well they retain their coldness. Even when they thaw to a gel state, they continue to cool effectively, maintaining the temperature of the contents in the cooler. This reliability means I no longer have to worry about buying bags of ice every time I go on a trip or have a picnic. Using the Cooler Shock Reusable Ice Packs has not only saved us money on ice purchases but also eliminated the mess and inconvenience caused by leaky traditional ice blocks. In conclusion, these Cooler Shock Reusable Ice Packs are a fantastic investment for anyone who needs a reliable and long-lasting cooling solution for their cooler. The ease of assembly, exceptional cooling performance, and overall quality make them stand out from other options on the market. If you want to keep your cooler contents perfectly chilled without any fuss, I highly recommend giving these ice packs a try!

great ice packs. its a little funky to fill them and make sure the air is out but they work great, highly recommend. Stays cold quite awhile. the better coolers obviouslly make them last even longer but they are good even in my old crappy igloo ones.

Why I bought: I needed something to keep my food and drinks cool for when I go mountain biking, golfing, or just packing simple lunches for myself, my wife, and my daughter. This is a really ingenious idea that allows for reusable, compact, ice packs that last a long time. My first purchase of these were in 2020 and they are still usable, 5 years later. I even bought smaller ones for small lunch boxes. The set up process is really easy and takes maybe 5-10 minutes and it comes with instructions. Highlights: - Variety of sizes and options - compact - stays cold for long periods - easy set up Low lights: - the edges can be a little sharp so just be careful

When I ordered these with the "some assembly required", I was prepared to be really irritated that I had to do the work to save them the money. But what I found was, it was actually fun putting it together and I was afraid of potential leaks, but out of the 5 I ordered (lunch size), all have had no issues whatsoever, which is surprising as I am not the IKEA assembly guy at all. I expected it would fail and it didn't.... not one drop spilled. The ONLY reason I gave 4 stars instead of 5 (should really be 4.3 ish) is their claims of 8 hours of "as cold as ice". That may be the case if you are using them at room temp, but I bought them to keep beers cold for a 4-5 hour golf round in 95 degrees and for that, it worked, but was dying after 4 hours and the beer was maybe 40 degrees... I prefer 34-36 degrees. Yes I am a beer prima donna. Skeptical on the 8 hour claim, and that is why I did not give 5 stars. But for what I needed, it worked great!!! Maybe the larger versions were the 8 hour ones. Meh. But these things coming out of a very cold freezer will burn your hands, be very careful! They are so flipping cold! Protect your hands if using a very cold freezer or you may get frostbite. If you doubt the colder than ice claim, put it in a deep freezer and lose a few fingers if you are not careful taking it out... Overall, no issues at all with the lunch size pack of 5. Durable, convenient, and definitely way better than ice, and other non-ice solutions we have used. And for me and my wife the money was well spent for sure. For 5 stars, and this is not just for this product, promise less and deliver a bit more. But this is pretty awesome compared to a lot of other products we have tried. We are considering the larger versions, based on the performance of the smaller items and may update this review based on that. May yet get 5 stars, we will see. 8.8/10 Have recommended to friends and family. Place this in the best triple walled cooler and you may have a cold beer next week... or at least a 40 degree beer....

These are hands down the best ice packs and I've tried out about 30 types. I use these every day for migraines. They last for several days in a well made cooler like yeti or igloo. They last maybe 2 days with a couple of them in fabric coolers in the open they last several hours. I shaped them more into a roll shape to use behind my neck. I actually got frostbite last summer from one of them they are that cold. Of the 5 of them I bought several years ago, only one has finally leaked and that's years of everyday use

If like me, you have been waiting for Cooler Shock to release a small-size version of their cooler pack for lunch bags, wait no longer - this is what you need in your life right now. Two months ago after I bought the medium pack ( 4 Mid Size Cooler Freeze Packs 10"x 9" - No More Ice! Cooler Shock Replaces Ice & Reusable. You Add Water & Save! ) and discovered arguably the best cooling pack on Amazon (don't take my word for it, read the reviews over on that product page), I came across a comment left by a Cooler Shock rep that they are working on a small size suitable for lunch packs, and I have been waiting patiently ever since. The medium pack is unparalleled in its performance - after an entire day at the office, I'll come home and my drink is still frozen. The issue that I and many others had was that the medium pack is a tiny bit too large in both dimensions for lunch bags - I had to fold the edges in to get it to fit. Well the solution is finally here. This lunch bag size cooling pack is the best of all worlds: - It uses the same tried-and-true material as other Cooler Shock packs: a phase-change material that can absorb an enormous amount heat without itself warming up. - The screw cap seal is the easiest to set up by far: prepping 4 medium packs with an iron took me almost an hour; by comparison, I had all 5 small packs set up in 10 minutes. - Unless you have a lunch bag for ants, this size will fit all lunch bags. If you can put a typical-sized tupperware in your lunch bag, this cooler pack will fit. - I've used it for a few days now and can confirm 10 hours of cooling. If you work a typical 9 - 5, that's more than enough to keep food at a safe temperature all day long from fridge (morning) to fridge (evening). It won't have the same 24 - 48 hour cooling duration as the medium pack, but that's overkill for lunch bags anyway. The only downside I can think of: - Not ideal for use in ice chests. But that's what the medium and large versions of the Cooler Shock are for anyway. If you have used Cooler Shock's other packs in the past, you know how good they are, and you won't be disappointed in the lunch bag packs. ==EDIT== I've now tested the Cooler Shock in an insulated lunch bag, sitting in a room kept at 70°F, monitored with a thermocouple - see the results in the picture. The ice pack started from the freezer at 4°F, reached 32°F at 10.1 hours, and reached 40°F (the maximum recommended temperature for keeping food refrigerated) after 12.2 hours - corroborating reviews from others reporting the ice packs lasting up to 12 hours.

I bought these because my fiance and I needed to start bringing lunch into work as good prices are just getting ridiculous to eat out. So, I bought the cooler pack and the lunchbox pack. These packs are amazing! Differences in use. I work in an office with limited fridge space and my fiance is someone who works outside a lot so a fridge isn't always available. So, saying this!!! The cooler packs are his, they keep his food cold for at LEAST 10 hours. By the time he is home his lunchbox isn't warm inside but it isnt as cold, but keep in mind he leaves his lunchbox in a hot car. I'm sure in the winter it'll be MUCH better, but it keeps his food cold for when it's time to eat and that's all that matters. Which he doesn't leave the lunchbox inside his hot car, the lunchbox is still very much cold when he brings it home. My experience with my lunchbox pack, again. My situation is different. I am inside a building where there's AC in the summer and heat in the winter. Pampered over here. So my lunchbox sits on my desk and I take my food out as I want it throughout the day. I USUALLY have a breakfast yogurt, a energy coffee drink and a protein shake. Sometimes I have veggies and fruits and hummus as well. The ice packs, I use all five, freeze my protein shake LOL! Sometimes my yogurt. I can put something in there that's warm and by the time I want it, it's COLD. My lunchbox feels like a literal fridge sometimes a freezer. Idk if it's the combination of the ice packs and the lunchbox, but I am VERY satisfied.

3 out of 5 stars, because only 3 out of the 5 in the pack had enough powder to turn to gel. 1 seemed like it had no powder, and water didn't gel at all. Another only had enough powder to partially gel.

It works exceptionally, I am really happy for my purchase. I tried to find the best cost/effectiveness and this was the result, it made me discover that the lunch bags we have has bad insulation. They are exceptionally cold for a minimum of 12 hours (in bad insulation) so I'm excited to use these in coolers for summer camping. Thank you so much for making a great product that's also fun to make! No regrets for this purchase.

Keeps cold for half the stated time Better than ice but bags are not as sturdy as the plastic counterparts

Brilliant!! I used these packs to keep pumped breast milk cold overnight in a cool bag and in my nappy while out and about. I have also used them to keep a dozen or so bags of breastmilk frozen while travelling. I use 2 of the packs overnight in a cool bag and the breastmilk is ice-cold - cold enough to put straight into the fridge. I use 1 pack in the front zip section of my backpack-style nappy bag that holds 3 bottles of breastmilk. The great thing about these packs here is that they are soft when room temperature so I mould them to fit into the small front compartment and then freeze - normal rigid ice packs don’t usually fit. I have used all 5 in my cool bag to keep my breastmilk bags frozen on 2 trips lasting 3 hours - they were still frozen solid at the end of both trips!! When I first read the info on these packs, I was worried that the breastmilk would freeze if a bottle was in contact with them. Luckily this has not been the case as you can control the amount of cooling with the number of packs. These cool packs have taken away so much of the hassle of expressing and storing breastmilk - one less stressor as a new mum!!

Went to Wales, left for 7am, and put this in a cooler for toddler's milk got back for 7pm and the milk was still cool temperature!! This are really good, especially the bigger packs. They say this lasts for 8 hours, it lasts for 10-12!!

Stay cool for more than 8 hours! Great all day in my kids’ lunch !
