Portable Peptide Cooler — XL keeps its interior at a steady 2–8°C and shows the live temperature on the lid, so the cold chain is something you can check rather than assume.
Portable Peptide Cooler — XL is a portable, USB-C rechargeable cooler that holds 20–25 standard vials, or 6–10 injection pens inside a locked 2–8°C window, accurate to ±0.5°C. It uses silent semiconductor cooling — no compressor, so no hum and no vibration.
The XL runs the same cooling engine as the Standard with roughly double the interior — a two-layer insert lets pens lie flat instead of stacking.
A domestic fridge swings between roughly 1°C and 12°C every time the door opens, and nothing on the shelf records that it happened. Portable Peptide Cooler — XL holds the window and prints the number on the lid. It measures 24 × 13 × 11 cm and weighs 1.4 kg, so it travels in hand luggage rather than staying at home.
Domestic fridges swing between 1°C and 12°C every time the door opens. Vials degrade at the top of that range, and nothing on the shelf tells you it happened. The Portable Peptide Cooler — XL holds a stable 2–8°C and shows the exact temperature on the lid.


Short clips — no sound needed.
Semiconductor cooling holds the cold-chain window temperature-sensitive vials need — no ice packs, no guessing, no 20°C spikes when the fridge door opens.
USB-C rechargeable. Runs from a power bank, a laptop, or a car socket, so the chain never breaks between the pharmacy and home.
No compressor, no rattle. Quiet enough to sit on a bedside table or a shared desk overnight.
Compact enough for hand luggage and a weekend bag. Travel without leaving your vials behind.
Medical-grade build, tested seals, replacement unit if the cooling module ever fails inside two years.
Silicone insert takes 8–10 standard 10ml vials, or 2–4 injection pens laid flat without rolling.

Set point, current temperature and battery on one panel.

Set your target once — it holds it until you change it.

Smaller than a paperback; fits a jacket pocket or a desk drawer.

Cooler, USB-C cable, mains plug, car adapter and silicone insert.

Matte white and glass — nothing clinical about the finish.

Charge, load, close. The chain follows you.
Identical cooling engine, identical 2–8°C accuracy and the same 2-year warranty. The only differences are capacity, battery runtime and footprint.

You carry one or two items at a time, want the smallest possible unit for hand luggage, and mostly carry vials with the occasional pen.
You keep a larger stock, share the unit at home, travel for longer than a weekend, or store several pens flat alongside vials.
Both models ship with your choice of US, UK or EU plug — selectable above — and run on 110–240V, USB-C or a 12V car socket.
The cold chain only counts if it survives the journey. These are the four places our customers tell us the cooler actually lives.

Verified customer feedback from across the UK & EU.
Took it abroad in cabin luggage with a power bank and it held temperature the whole way. Genuinely silent - no compressor hum at night.

Shipping to mainland EU took 3 working days, tracked the whole way. Arrived undamaged and the lid seal is tight. Reordering the XL next month.

The little details matter - the silicone insert stops everything rattling and the lid closes with a proper seal rather than a plastic click.

Support answered a battery question within a few hours over email. Rare to get that level of response. The unit itself is exactly to spec.

Ordered late Monday, arrived Wednesday morning in the UK. Sat at 4°C within about fifteen minutes of switching it on and hasn't drifted since.
Everything about this feels professional - from the site to the packaging to the finish on the housing. Temperature matches my own probe.
More storage from the PeptidesFridge range.
Straight answers on cooling, power, shipping and warranty.
It holds a 2–8°C window to within ±0.5°C using semiconductor cooling. The lid display shows the measured internal temperature, not just the set point, so you can confirm the chain at a glance.
It takes 20–25 standard vials, or 6–10 injection pens. A silicone insert stops everything rattling; pens sit flat rather than rolling.
Up to 30 hours on a full charge. It charges over USB-C and will run from a power bank, a laptop, a mains adapter or a 12V car socket.
Choose UK (Type G), EU (Type C) or US (Type A) at checkout. Every unit accepts 110–240V, so the plug is about the socket, not the voltage.
The unit is cabin-legal in size and can go in hand luggage. Charge it before you fly or run it from a power bank. Check the rules for whatever you carry inside it.
2 years on the cooling module, battery and display. If it fails in normal use we replace the unit. Accidental damage, liquid ingress and unauthorised repair are not covered.
