Travel Power Strips for Hotels, Planes and Dorms
The Anker 521 Power Strip is our top pick for combining two mains outlets with high output USB-C in a genuinely pocketable block. The Belkin BST300 SurgePlus is the value choice with real surge protection, and the TESSAN Travel Power Strip adds a longer cord for awkward rooms.
The Anker 521 Power Strip tops this roundup because it fits two mains outlets and useful USB-C wattage into a block small enough to forget in a bag, which is the specific problem a hotel desk with one accessible socket creates. The Belkin BST300 SurgePlus is the value pick and adds genuine surge protection, while the TESSAN Travel Power Strip is the choice when the only free socket is behind the bed.
Travel power strips are easy to buy badly because the compact ones often skip surge protection entirely, and the ones with real protection are frequently too bulky to justify packing. Voltage compatibility adds another trap for international trips. We compared outlet counts and spacing for chunky adapters, USB-C and USB-A output, surge joule ratings, cord length and plug swivel, plus packed size and weight, then weighed those against what owners report about strips that block adjacent sockets or run warm under load.
The best picks, ranked
Anker 521 Power Strip
Anker packs two mains outlets and both USB-C and USB-A into a cube small enough to sit on a hotel nightstand without dominating it. The USB-C output is high enough to charge a laptop rather than just a phone, which removes a second brick from the bag. Based on specifications it is the most useful power to volume ratio here.
Pros
- USB-C output can charge a laptop
- Replaces several separate chargers
- Small enough to pack without thinking
Cons
- No surge protection rating
- Short cord limits placement
Belkin BST300 SurgePlus USB Swivel Surge Protector
Belkin builds this as a wall tap with a swivelling plug, so it rotates out of the way of adjacent sockets and furniture rather than blocking them. Unlike most compact travel blocks it carries an actual surge protection rating. Three outlets plus USB covers a laptop, a phone and a camera charger simultaneously.
Pros
- Genuine surge protection in a travel size
- Swivel plug avoids blocking nearby sockets
- Three outlets in a wall tap format
Cons
- USB-A only, no USB-C
- No cord, so it depends on socket position
TESSAN Travel Power Strip with USB Ports
TESSAN adds a genuine cord to the compact strip formula, which solves the very common hotel problem of the only free socket being behind a bed or under a desk. Outlets are spaced to take at least one bulky adapter. It packs less neatly than a cube, but the cord is often the difference between using it and not.
Pros
- Cord reaches sockets behind furniture
- Sensible spacing for chunky adapters
- Flat profile packs against a laptop
Cons
- Cord adds bulk over a cube style unit
- Surge rating is modest
NTONPOWER Travel Power Strip
NTONPOWER’s design wraps its cord around the body, which sounds like a small thing until you have untangled a strip in a dark hotel room. It combines mains outlets with USB in a slim housing. Charging speeds on the USB ports are moderate rather than fast, so a laptop still needs its own supply.
Pros
- Cord stores neatly against the body
- Slim shape packs flat
- Several USB ports for family travel
Cons
- Moderate USB charging speeds
- Not enough output for laptop charging
Tripp Lite TRAVELER3USB Travel Surge Protector
Tripp Lite comes from the professional power protection side of the market and this travel unit reflects that, with a proper surge rating and diagnostic indication of protection status. If you travel with expensive camera or audio equipment, that matters more than an extra USB port. It is chunkier than the minimal travel cubes.
Pros
- Serious surge protection for the size
- Indicator shows protection is still active
- Established brand in power protection
Cons
- Bulkier than minimal travel blocks
- USB-A only
Accell Home or Away Surge Protector
Accell uses a flat folding plug and widely spaced outlets, which suits a dorm desk pushed back against a wall where a standard plug would not fit. Surge protection is included. It is a little larger than the pocket cubes, sitting between a permanent desk strip and a travel accessory.
Pros
- Flat plug fits behind furniture
- Wide outlet spacing for adapters
- Doubles as a permanent desk strip
Cons
- Larger than pocket sized options
- Basic USB output speeds
BESTEK Universal Travel Adapter with Power Strip
BESTEK combines a multi outlet strip with international plug compatibility, which is the format that makes sense when you land somewhere with a different socket standard. Note that plug adapters change the pin shape only, so check that everything you plug in is rated for the local voltage. It is the bulkiest option here and the one that earns that bulk abroad.
Pros
- One unit covers multiple plug standards
- Several devices charge from one wall socket
- Removes the need for multiple adapters
Cons
- Bulkiest and heaviest option here
- Does not convert voltage, only plug shape
How to pick the right one
Adapters change plug shape, never voltage This is the mistake that destroys equipment abroad. A travel adapter alters the pin configuration so your plug fits the wall. It does nothing to the voltage arriving at the device. Check the small print on each charger for a range such as 100 to 240 volts, which almost all modern laptop and phone chargers carry. Anything rated for a single voltage, including many hair appliances, needs a converter rather than an adapter.
Surge protection and what the joule rating means Joules describe how much energy the protection can absorb before it is used up. Most ultra compact travel blocks contain no surge protection at all, which is fine for a phone and questionable for a laptop in a building with unreliable power. If you travel with expensive equipment, choose a unit with a stated rating and a status indicator so you know the protection has not already been consumed.
Outlet spacing beats outlet count Three outlets that cannot each accept a wall wart are worse than two that can. Look at how the sockets are arranged and whether at least one position takes a chunky adapter without covering its neighbour. Cube shaped strips with outlets on different faces handle this better than a flat row. The same applies at home, where a blocked outlet is a wasted one.
Weight, cord length and the airline question A cord is often what makes a strip usable, since hotel sockets hide behind beds and desks. Balance that against packed bulk. On aircraft, seat power delivers limited wattage and cabin crew commonly ask passengers not to use power strips at all, so plan to charge devices before boarding rather than relying on the seat outlet. Never daisy chain one strip into another.

Frequently asked questions
Will a travel power strip work overseas?
The strip works if it is rated for the local voltage, which most modern units with USB charging are. The plug will not fit without an adapter for the destination. Check the input rating printed on the strip for a range such as 100 to 240 volts before travelling.
Do I need surge protection in a travel power strip?
It depends on what you plug in. For phone charging it is a minor concern. For a laptop, camera batteries or audio equipment in a building with uncertain wiring it is worth having, and many compact travel blocks omit it entirely despite implying otherwise.
Can I use a power strip on a plane?
Many airlines discourage or prohibit it, and seat power outlets deliver limited wattage that a strip can easily exceed, causing the outlet to cut out. Charge devices before boarding and use a single charger at the seat rather than a strip.
How many outlets do I actually need?
Two to three mains outlets plus a couple of USB ports covers most travellers, since phones, tablets and headphones charge over USB and only a laptop typically needs a mains socket. More outlets means more bulk for capacity you will rarely use.
Is USB-C worth having on a travel strip?
Yes, particularly if the port delivers enough wattage to charge a laptop. That removes an entire power brick from your bag. Check the stated output, since a low wattage USB-C port charges phones only and offers little advantage over USB-A.
Can I plug a power strip into another power strip?
No. Daisy chaining strips is a recognised fire risk because it allows the total load to exceed what the wall circuit and the first strip are rated for, and protection devices cannot account for it. Use one strip per wall socket.
What is the difference between a surge protector and a power strip?
A power strip simply splits one outlet into several. A surge protector adds components that absorb voltage spikes, rated in joules. Every surge protector is a power strip, but many power strips offer no protection at all despite similar appearances.
Are travel power strips safe in older hotels?
A properly rated strip is generally safe, but older buildings may have ungrounded two pin sockets, in which case surge protection cannot function correctly. If you are travelling with expensive equipment and the socket has no earth pin, treat any protection as unavailable.
Our take
For most travellers the Anker 521 Power Strip is the best pick because it turns one hotel socket into mains plus laptop capable USB-C in something the size of a small block. The Belkin BST300 SurgePlus costs less and adds real surge protection, which matters more if you travel with expensive gear. When the only available socket is behind the bed, the TESSAN Travel Power Strip and its cord solve the problem the others cannot.
