Yes. The Secrets Box is TSA-compliant for medication on flights. The rules for power banks on flights are set by the airline, so it is worth checking its policy in advance.

Guide: Flying with refrigerated medication from Israel

There is no such thing as a TSA approval for medication fridges. The Secrets Box is TSA-compliant for medication on flights, and comes with you into the cabin.

No. The box includes a USB to USB-C cable, a wall charger and a bio-gel ice pack. Connect to a wall outlet, or to a 10W power bank (20,000mAh or more recommended, 10,000mAh works too). The power bank is sold separately.

There are three layers. When there is an outlet, at home or at the hotel, The Secrets Box holds 2 to 8°C (36 to 46°F) with no time limit, as long as it is plugged in. When there is no outlet, connect a 10W power bank, or a USB adapter for the car's 12V socket (both sold separately). And if that is not available either, the box includes a bio-gel ice pack as a backup. According to supplier data: 33 hours at 30°C (86°F), 30 hours at 35°C (95°F) and 28 hours at 40°C (104°F).

The Base model weighs 800 g (1.8 lb), and XL 2.0 weighs 900 g (2 lb). The fridge travels with you into the cabin and not in your suitcase, so it adds no weight to it. XL 2.0 is carried over the shoulder, in the carry bag that comes in the box.

As long as it is connected to a 10W power bank (sold separately), The Secrets Box holds a steady 2 to 8°C (36 to 46°F) with no time limit, and the display shows it at every moment. You can also plug into a seat outlet or USB port, when the seat has one. Not every airline or aircraft has one, so a power bank (sold separately) is a good idea. We recommend telling the cabin crew that you have a medication fridge with a power bank, and they will guide you on using it during takeoff and landing. As a backup, the included bio-gel ice pack keeps things cold for 33 hours at 30°C (86°F), 30 hours at 35°C (95°F) and 28 hours at 40°C (104°F), according to supplier data.

Plug into an outlet with the included charger, and it stays at 2 to 8°C (36 to 46°F) for as long as it is plugged in. No need to look for a hotel with a fridge. In the car, connect through a USB adapter for the 12V socket (sold separately).

No. The Secrets Box has no power-disconnect alert. The temperature is always shown on the digital display, so it is worth glancing at it from time to time to make sure the fridge is connected and on.

In continuous use for more than 4 days (on an outlet, a power bank or any other power source), we recommend unplugging the fridge for a 20 to 30 minute break now and then, and, about once every 3 months as the manufacturer recommends, cleaning the vents on the cooling head with an air blower or a hair dryer on the cool setting, to get dust out. That keeps the fridge going for the long run. This is a maintenance tip: as long as The Secrets Box is connected to power, it holds 2 to 8°C (36 to 46°F).

It is quiet, under 40dB, so you can leave it on the desk or next to the bed. After a few days of continuous use the fan works harder, and half an hour of rest brings it back to quiet.

The number depends on pen size: both models hold up to 7 pens the size of Lantus and up to 5 the size of Ozempic, and for wider pens the number depends on the pen type and the model. Each model has its own list, because the cooling canister is different (XL 2.0: 6.2 cm wide and 18 cm tall, Base: 5 cm wide and 16.5 cm tall). Can't find your pen? Message us on WhatsApp.

Medications that need refrigeration in the 2 to 8°C (36 to 46°F) range, such as biologic medications, insulin, GLP-1, fertility treatments, growth hormone, vaccines and eye drops. Fit depends on pen size, and the full list for each model is on the pen list.

In XL 2.0 the cooling canister is larger (6.2 cm wide, 18 cm tall), it reaches 2 to 8°C (36 to 46°F) in 15 to 20 minutes, and it comes with 4 gifts. In the Base model the canister is 5 cm wide and 16.5 cm tall, and it reaches the range in 20 to 30 minutes. The outer body is the same, 26 by 8.5 cm.

Yes. The XL 2.0 canister (inner width 6.2 cm, height 18 cm) is sized for 2 standard breast milk storage bags, each holding up to 200 ml (6.8 fl oz). Measure your bags first, since dimensions vary between brands. The fridge cools and does not freeze: a smart system prevents freezing. Its range is 2 to 8°C (36 to 46°F). The CDC recommends storing freshly pumped breast milk in a refrigerator at 4°C (40°F) or colder, so it is important to know: the display shows the temperature at every moment, and the decision is yours.

The Secrets Box holds a range of 2 to 8°C (36 to 46°F), and it is meant for medications that need refrigeration. If your medication should be kept at room temperature, this is not the right product for it. What suits your medication is written in its patient leaflet.

Freeze the bio-gel ice pack at least 12 hours ahead (easiest: from the night before), wet it with water and wait about 2 minutes, put it in with the medication and close with the regular lid included in the box. The medication does not touch the ice pack directly. Put it in the protective pouch, or wrap it in another insulating material. Without power, the ice pack keeps the cooling range for 33 hours at 30°C (86°F), 30 at 35°C (95°F) and 28 at 40°C (104°F), according to supplier data.

The Secrets Box costs ₪749 for the XL 2.0 model and ₪699 for the Base model. Shipping in Israel is free, and you can pay in up to 3 installments, at checkout. The power bank is sold separately.

Because it is an electric fridge, not a regular cooler bag: an electric cooling head, an aluminum cooling canister and a display that shows the temperature at every moment.

You pay once and take it on every flight, trek and long day.
