Hot BentoSelf Heated Lunch Box and Food Warmer – Battery Powered, Portable, Cordless, Hot Meals for Office, Travel, Jobsite, Picnics, Outdoor Recreation, Kitchen Meal Prep, Black

Very good product. We are 3/4 of a way done with the school year and the electric component still works very well. The instructions are not great but once you figure out that you pretty much have to charge it for about 2 hours and that you're going to get 15 to 20 minutes of heat out of it. That's all. A child really needs to heat up their lunch. I took it to work a couple times myself as well. Pretty convenient.Unfortunately we did have an issue with the plastic top fasteners. One of them broke off and now less than a few days later the others are starting to break. They sell replacement tops on their website! 5/5 no other product like this really, especially at this size.

The first thing I worried about was the tray being a bit too shallow, but it works decent for my food servings. It does get the food hot in about 15 minutes and if used to reheat burgers, it actually gets a bit too hot in the time frame. Keep in mind that moist foods tend to get pretty hot as only the bottom of the pan gets hot. The juicier food will transfer heat better. Those are all positives.As for negatives, the largest negative, by far is that the device is completely glued together. This means that once your lithium-ion cells start to go bad, you are expected to trash the warmer and purchase another brand-new unit. I contacted the manufacturer about replacement batteries, but they simply ignored my email. As a comparison, LunchEAZE is another food warmer that is battery powered. The difference is that the company responds to email in one day and sell replacement parts. The battery can be replaced with a Philips screwdriver. They also use 8 lithium-ion cells in a 7.4-volt 2s4p. The Hot Bento uses only 4 cells in a 14.8-volt 4s1p configuration which will get hotter but for a shorter time. Expect to have under one year of usage from Hot Bento then to the trash it goes.The tray isn't removable which makes cleaning quite an annoying task as you are instructed to not run it under water. The included charger is a 1A 16.8v charger which takes a few hours to fully charge the warmer while the luncheaze includes a 3A charger. If Hot bento included an actual 2-amp charger, it would take nearly half the time to charge. This is what I do and get a full charge in a little more than 1 hour. Keep in mind that many 2-amp rated chargers lie about capacity. With some calculation, the device uses 8 amps during use while the Luncheaze can use up to 2 amps. Due to this design, the Luncheaze can actually run while plugged in if you forget to charge the device while the Hot bento cannot due to its included 1 amp charger and design. It would need more than 8 amps to run and charge simultaneously.When my battery fails in a few months, I plan on making this a device that I really like by adding 8 batteries in a 4s2p configuration and charging at 4-amps instead of 2.This thing can easily be made by using 2 thermoelectric blocks (which they use), a normally closed temperature disconnect switch, some relays, latching circuitry and a bms to disconnect the battery at low voltage. The batter charging is handled by a 4s smart charger.I fear that when the battery starts to lose capacity, the device will become completely worthless for those that expect a reliable product.UPDATE: I just had to lower the initial after realizing how important customer service is. I received a broken Luncheaze unit from someone that got theirs replaced with no questions asked almost a year after purchasing it. Hot Bento only has a 90-day warranty as it makes sense that they typically fail within a year and no replacement parts and a completely glued unit that serves to keep you from servicing the unit. I also have no plans on upgrading the unit as its just collecting dust now.Luncheaze customer support replied to my questions within a day and within a few minutes for the last few questions I had about replacement parts. The parts were shipped the following day and they worked out free shipping on the accessories that I purchased as an extra.Edit 2: notice the people with failed units exactly as I mentioned.

Was skeptical by the reviews but decided to purchase this anyway for a trip. One of my children has food allergies and I wanted to give them options besides sandwiches. This did just the job. It is not very deep and probably wouldn’t be enough for a grown adult but it was perfect for a child. As mentioned in the reviews, you can only do one heating per charge and the charge took about 2 hours. The device was easy to carry and didn’t get hit when heating up, just warm. Overall, great product and I am so happy to have it.

My husband cannot tolerate most food in our Retirement Community Dining Room, because of severe reaction to Gluten, Dairy, and assorted other new limitations. Therefore he must prepare his own food to take to the Dining Room when eating with friends. When the first Bento Box arrived he found the heater did not work. He was not refunded for the old one, but instead had to pay for a new one!

A little pricy but worth it in my opinion. I eat my lunch in my car at work and having a hot option is amazing. The size is perfect for a single meal. Very easy to clean. Ive been using this for a few months now and still working great. Battery is a little limited but as long as you charge it everyday it works perfectly.

It’s okay. Yes, it works. But it’s kinda quirky.Pros:-hot meals in remote locations without microwave or electricity-reasonably sized compartment for single meal-fairly durableCons:-cumbersome to clean (does not disassemble without destroying the unit)-sometimes uneven heating-battery gives you exactly 1 shot at warming up your food (does not keep food warm or reheat again without a several hours-long recharging)-comes with wall plug but not car plugOverall I will look at alternatives when it comes time to replace this unit. Perhaps something with the ability to wash, food tray comes apart, longer battery life and ability to plug into car outlet.

Purchased this for my autistic daughter, who will not eat sandwiches or cold food. I was taking her on a camping trip and had rented a pontoon boat. Figuring out how to provide her with warm food while sitting in the middle of a lake for 6 hours per day was having me at my wits end, until I discovered this on Amazon. Crossed my fingers and purchased it. Before we left for our trip, I cooked a few portions of spaghetti for her and placed them each in plastic baggies in our cooler. Each mornign at the lake, I took a bag of the spaghetti out of the cooler, placed it COLD into this container and closed it up. Hours later, in the middle of the lake, I pulled the container out, pressed the button and about 12 minutes later, the spaghetti was at the perfect temperature for her to eat.Every evening when we'd get back, I plugged it into our generator for it to charge. The next day, repeat the process. Since that trip I've used it a few additional times, when we are taking her on a long car ride and are going to have to eat in the car. Pack her food in it, a few hours later while driving, press the button and boom, hot food.
