The travel adapter that locks into the wall so it never wiggles loose at 9pm in a foreign hotel. Slide-lock pins for US, UK, EU & Australia, with surge protection + a replaceable fuse so your expensive gear is protected, not gambled.
You know the 9pm hotel moment - phone at 8%, the outlet's loose, and your adapter keeps drooping half-out of the wall. One brick for US, UK, EU and Australia that slides, clicks and locks in. Plug in clean and stop thinking about power.
The single failure every universal adapter shares is the same one editors quietly list under "cons" - it works fine until it slowly droops out of the wall. Borsyn's slider deploys the pins and physically secures them.
The old way
Loose from the first night
Nothing holds the pins in. The weight of your charger drags it half-out, the light flickers, and you're propping it up with a shoe at 9pm.
The Borsyn way
Slide, click, locked
The slider deploys the right regional pins and secures them in place. There's nothing loose to fall out - it sits flush and stays put the whole trip.
Slide, click, locked - nothing loose to lose.
One slider selects and secures the exact pins you need for where you've landed. No wrong plug, no wiggle, no scramble.

"Are universal adapters safe?" is one of the first things travelers Google - because a cheap brick can spark, overheat, or spike your gear. Borsyn is engineered to guard your devices, not risk them.
Three layers between the wall and your gear.
Surge protection sits inline to absorb voltage spikes before they reach your device. A replaceable fuse cuts overloads. A fire-retardant shell contains heat. That's the difference between a real travel adapter and a $5 airport plug.
3layers of protection working at once
Inline surge protection
Absorbs sudden voltage spikes from unfamiliar foreign outlets before they ever reach what's plugged in.
Replaceable fuse
An overload trips the fuse instead of your gear. Swap it and you're back in business - no dead adapter.
Straight answer, no confusion: Borsyn is a plug adapter with surge protection - it changes the plug shape so your phone, laptop and tablet fit foreign outlets and charge safely. It is not a voltage converter, so it's not for single-voltage appliances like hair dryers or curling irons. For the gear you actually travel with, this is exactly what you need.
One Brick, Every Trip
US. UK. EU. Australia. Packed As One Thing.
No more drawer of single-region plugs, no more airport markup for a set that takes up space. The regions you actually visit, deployable from one slider - and a universal socket that takes almost any plug you already own.

Three plug types, one slider
Slide to deploy the US/AU, EU, or UK pins for wherever you've landed - then lock them in place. Land in London, slide to UK. Fly to Rome, slide to EU. Same brick, every time.

One Thing, Every Trip
The Moments It Quietly Handles
You don't think about a great travel adapter - that's the whole point. Here's where it earns its spot in the carry-on.
The 9pm arrival
Land, plug in, exhale
Long-haul over, phone at 8%. It slots in clean on the first try and locks - no propping it up with a shoe.
Carry-on ready
Fits beside the passport
One compact brick replaces the drawer of single-region plugs. It disappears into a pocket next to your documents.
The multi-country loop
Four countries, zero swaps
Rome, Paris, London, then home. Slide to the region you land in - one adapter carries the whole itinerary.
The useful gift
The one they'll actually use
Most travel gadgets are gimmicks. A lock-in adapter is the gift the frequent flyer in your life reaches for every single trip.
Before You Pack It
The Questions Travelers Ask First
Straight answers - starting with the two things everyone worries about most.
It stays. The lock/unlock slider doesn't just deploy the regional pins - it secures them in place, so there's nothing loose to fall out. Even with the weight of a charger hanging off it, it sits flush and holds. That "sliding half-out of a loose hotel outlet" problem is exactly what the lock was built to end.
Borsyn is built with three safety layers: inline surge protection to absorb voltage spikes from unfamiliar outlets, a replaceable fuse that trips on overload instead of your gear, and a fire-retardant shell. It's designed to protect the expensive electronics you plug into it - not gamble with them.
It deploys pins for the US/Australia, Europe (EU), and the UK - the regions most travelers actually visit. On top of that, the front has a universal AC socket that accepts almost any plug shape from any region, so the charger you already own goes straight in. Think Italy, France, Ireland, the UK, most of Europe, and Australia from a single brick.
It's a plug adapter with surge protection - not a voltage converter. In plain terms: it changes the plug shape so your phone, laptop, tablet, camera and other chargers fit and charge in foreign outlets. It is not for single-voltage appliances like hair dryers or curling irons. For the gear travelers actually pack, this is exactly what you need - and nothing you don't.
Yes. The universal AC socket takes your existing charger - which means you can run a multi-port charging block or power strip through it and keep several devices topped up from a single foreign outlet. One wall socket, your whole kit charged.
Shipping is free worldwide on every order. Order ahead of your trip and it lands in the carry-on before you fly - no airport-kiosk scramble at a markup.
You're covered by a 30-day money-back guarantee - if it's not right for you, send it back for a full refund. Every Borsyn also comes with a 1-year warranty, so a real problem gets a real fix.

Compact, reliable, and easy to pack.
"Our family travels abroad often, and our old adapters are messy and outdated. This compact travel adapter has retractable plugs and comes with a durable storage pouch.
It offers US, UK, Euro and Aussie plug types, plus two USB‑A and two USB‑C ports for convenient charging.
It stays cool even when powering multiple devices at once. I haven’t tested all international sockets yet, but every available function works reliably."
★★★★★✓ Verified
A must-have for future overseas trips.
"This lightweight, ultra‑thin adapter easily slips into a pocket or tech pouch, perfect for efficient packing.
Equipped with four USB ports and built‑in safety protection, it charges several gadgets at the same time.
It works in over 200 countries. Just note it is only a plug adapter instead of a voltage converter.
It saves lots of luggage space and will be my must‑have gear for all future overseas trips."
★★★★★✓ Verified
Reliable across Europe and Southeast Asia.
"I used this adapter during my trips around Europe and Southeast Asia. The slide‑out plugs operate smoothly and stay firmly locked.
Thanks to GaN technology, it remains cool with multiple devices charging simultaneously.
The shared 25W output slows down laptop charging a little, and it is thicker than advertised.
Even with minor flaws, its compact size and practical design earn it a permanent place in my travel bag."
★★★★★✓ Verified
Fast charging without extra bricks.
"I travel frequently to the Middle East, and loose wall sockets always trouble me with my old chargers.
It features two USB‑C and two USB‑A ports as well as retractable plugs, so no extra charging bricks are needed.
Simple switches convert between US and European plugs, and fast USB‑C charging works great.
It includes a fabric storage pouch, and I plan to buy several units for every family member."
★★★★☆✓ Verified
Compact and dependable after a month.
"This adapter is roughly two‑thirds the size of most competing models while weighing about the same.
It charges my iPhone, MacBook and power bank steadily without any problems after one month of use.
I have not tested its international plug configurations yet, but it performs excellently with US outlets.
Overall, it is a fantastic travel adapter with no obvious downsides."
★★★★★✓ Verified
No loose pieces to lose.
"All plugs are integrated into the unit, so there are no small loose pieces that may get lost while traveling.
Multiple USB ports replace separate wall chargers and outperform basic simple plug converters.
The practical design is easy to operate, yet some rivals support more countries and richer charging options.
It is still a dependable choice and quite useful for most international travel scenarios."
★★★★★✓ Verified
Now I carry it on every trip.
"I originally bought it for overseas trips, and now I carry it for every journey including US domestic travel.
Its ultra‑slim body saves plenty of bag space, turning one outlet into four USB ports plus an AC socket.
It delivers stable 25W charging but cannot reach top speeds for high‑power gadgets.
The stylish white and black finish looks nice, and it is an indispensable portable travel charger."
★★★★★✓ Verified
One adapter instead of a pile.
"I was tired of carrying a pile of different adapters for my international business trips. This all‑in‑one design solves that problem perfectly.
The sliding plugs lock securely, and the built‑in USB ports cut down on messy cables in my bag.
The solid construction feels durable, and the heat stays under control even during long charging sessions.
It balances portability and functionality really well, and I would happily recommend it to frequent travelers."
