Portable Peptide Cooler — Standard 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 — Standard is a portable, USB-C rechargeable cooler that holds 8–10 standard vials, or 2–4 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 Standard is the travel size: it fits a jacket pocket or a glovebox, holds a single active protocol, and runs a full day away from mains power.
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 — Standard holds the window and prints the number on the lid. It measures 18 × 10 × 9 cm and weighs 0.9 kg, so it travels in hand luggage rather than staying at home.
The problem
A kitchen fridge is the worst place for temperature-sensitive vials
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 — Standard holds a stable 2–8°C and shows the exact temperature on the lid.
Stable 2–8°C instead of uncontrolled door swings
Live LED read-out — you can see the chain is intact
Discreet: no vials sitting between the milk and the eggs
Portable: the cold chain travels with you

Built for the cold chain
Locked at 2–8°C
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.
Up to 24h on battery
USB-C rechargeable. Runs from a power bank, a laptop, or a car socket, so the chain never breaks between the pharmacy and home.
Silent by design
No compressor, no rattle. Quiet enough to sit on a bedside table or a shared desk overnight.
Cabin-friendly
Compact enough for hand luggage and a weekend bag. Travel without leaving your vials behind.
2-year warranty
Medical-grade build, tested seals, replacement unit if the cooling module ever fails inside two years.
Fits vials and pens
Silicone insert takes 8–10 standard 10ml vials, or 2–4 injection pens laid flat without rolling.

Pick Standard if…
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.
Pick XL if…
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.

Where customers keep it
The cold chain only counts if it survives the journey. These are the four places our customers tell us the cooler actually lives.
On the move
In the car
Runs off the 12V socket, so a three-hour drive never breaks the chain.
At home
On the bedside table
Silent semiconductor cooling — no compressor hum through the night.
Travel
In the travel bag
Cabin-legal size, charged before you leave, powered by a bank in the air.

Battery lasts longer than stated
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.

Quality packaging, quick dispatch
Second unit from PeptidesFridge. The display reads the real internal temperature, not the set point, which is exactly what I wanted.

Took it abroad in cabin luggage with a power bank and it held temperature the whole way. Genuinely silent - no compressor hum at night.

Portable Peptide Cooler — Standard — frequently asked questions
Straight answers on cooling, power, shipping and warranty.
How cold does Portable Peptide Cooler — Standard get, and how stable is it?
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.
What fits inside Portable Peptide Cooler — Standard?
It takes 8–10 standard vials, or 2–4 injection pens. A silicone insert stops everything rattling; pens sit flat rather than rolling.
How long does it run away from mains power?
Up to 24 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.
Which plug do I get?
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.
Can I take it on a plane?
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.
What does the warranty cover?
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.
