I’ve tested 8 universal travel adapters, 6 portable chargers, 4 mini power strips, and dozens of cables across 50+ international trips. Here’s the actual travel power stack that works.
The TL;DR — what you actually need
- One universal adapter with built-in USB-C ports (Tessan or EPICKA)
- One portable charger 10,000-20,000mAh (Anker PowerCore Slim)
- One short USB-C charging cable for laptop (5 ft braided)
- One mini power strip for hotel rooms with single outlets
Total cost: ~$80-120. This setup handles every country, every device, every situation I’ve encountered.
Universal travel adapters — the 8 tested
1. Tessan Universal Travel Adapter — $30 (Best overall)
Outlets: US (Type A), UK (Type G), EU (Type C), Australia (Type I)
USB ports: 4 USB-A + 1 USB-C (with PD)
Max output: 5,600 watts
What’s great: Compact, all-in-one design, USB-C with Power Delivery (charges laptops), included travel pouch
This is my current daily driver. The USB-C PD port charges my MacBook directly without needing the brick. Five total USB ports means partner + I can both charge phones + laptops + smartwatch simultaneously from one outlet.
2. EPICKA Universal Travel Adapter — $24 (Best budget pick)
Outlets: US, UK, EU, Australia
USB ports: 4 USB-A + 1 USB-C
What’s great: Same form factor as Tessan at $6 less. Slightly less power output (3,500 watts vs 5,600).
Functionally equivalent to Tessan for most travelers. Save the $6 unless you specifically need more wattage (rare).
3. NEWVANGA Universal Travel Adapter — $19 (Cheapest decent option)
Outlets: US, UK, EU, Australia
USB ports: 3 USB-A + 1 USB-C
What’s not great: No USB-C PD (slow charging for laptops via USB-C)
4. Mophie All-in-One Travel Charger — $90 (Premium, overpriced)
Includes wireless charging on top. Useful if you have a phone that supports wireless. The Tessan + a separate wireless pad is cheaper.
5-8. Other adapters tested and skipped
- Anker 526 Travel Adapter: Anker quality but $60 — too expensive for what it offers
- Belkin BoostCharge: Basic, no USB-C PD, $25
- Generic Amazon brands under $15: Often fail within 6 months
- Cube-style adapters with sliding pins: The pins jam over time
Portable chargers — the 6 tested
1. Anker PowerCore Slim 10,000mAh — $30 (Best for most travelers)
Capacity: 10,000mAh (charges iPhone 15 Pro ~2x)
Output: 1 USB-C PD + 1 USB-A
Weight: 7.5 oz
What’s great: Slim design fits in jeans pocket, fast charging, reliable
This is the sweet spot of capacity to weight to price. Two full phone charges, lasts a full day of travel use. Slim enough not to be annoying in your pocket.
2. Anker 737 PowerCore 24K — $100 (For heavy travelers)
Capacity: 24,000mAh (charges MacBook Pro fully)
Output: 2 USB-C + 1 USB-A, all PD
Weight: 22 oz (heavy)
What’s great: Can fully charge a 16″ MacBook Pro. Multi-device. Best for digital nomads.
Heavy. But for digital nomads working from cafes/coworking spaces, this charges your laptop when outlets are scarce.
3. Anker MagGo 5K Slim — $50 (Best for iPhone users)
MagSafe magnetic mount on the back. Snaps to iPhone 12+. Slim, integrated charging stand. Useful for hotel desk setups.
4. Mophie Powerstation Pro AC — $200 (For tablets + cameras)
Includes a real AC outlet for charging cameras, drones, anything else. Heavy and expensive but unique.
5-6. Power banks to skip
- $15 Amazon brands: Capacity is usually overstated by 50%+
- Solar-powered packs: Solar charging is so slow it’s useless; just buy a normal bank
Cables — what to pack
The minimal cable kit (4 cables)
- USB-C to USB-C, 5 ft braided — For laptop charging + USB-C phones. Anker brand reliable.
- USB-C to USB-C, 1 ft — For connecting to portable charger when in pocket/bag
- USB-A to Lightning (if you have any older Apple devices)
- USB-A to Micro-USB — For chargers, e-readers, older devices
Braided cables last 5-10x longer than standard rubber. Worth the $4-6 extra per cable.
The hotel power strip trick
Older hotels often have ONE outlet in the room — split between bedside lamp, AC unit, and TV. You can’t charge anything.
Solution: One mini travel power strip. Anker PowerStrip Mini ($25) has 3 AC outlets + 3 USB ports + 1 USB-C, weighs 6oz. Folds flat for packing.
Plug your travel adapter into the wall, then plug the power strip into the adapter. Suddenly you have 6 outlets in a hotel that gave you one.
The complete travel power stack — recommended set

This setup handles every country I’ve visited, every charging situation, every device.
What NOT to buy
- Multiple country-specific adapters. One universal beats 4 specific ones.
- Voltage converters. Modern electronics (laptops, phones) handle 100-240V automatically. Voltage converters are only needed for hair dryers, curling irons — and even then, buy a dual-voltage version of the device instead.
- Surge protectors marketed as travel adapters. Travel surge protectors generally don’t work — they need specific outlet types they can’t always match.
- Wireless charging pads as travel gear. Wireless charging is slow + still requires an outlet. Skip for travel.
FAQs
Do I need a voltage converter for international travel?
Almost never. Modern laptops, phones, tablets, cameras, and most electronics handle 100-240V automatically (check the AC adapter label). You only need a voltage converter for resistive heating appliances like hair dryers or curling irons – and even then, buying a dual-voltage version of the device is simpler.
What’s the best universal travel adapter?
Tessan Universal Travel Adapter ($30) is the best for most travelers. Compact all-in-one design, 4 USB-A + 1 USB-C PD port, works in 150+ countries. EPICKA at $24 is functionally equivalent for $6 less. Skip cheap Amazon brands – they often fail within 6 months.
How big of a portable charger do I need for travel?
For phone-only charging: 10,000mAh (Anker PowerCore Slim, $30) handles 2 full phone charges, lasts a full day. For laptop charging on the go: 24,000mAh+ (Anker 737, $100) fully charges most laptops. Don’t carry more capacity than you need – they’re heavy.
Can I bring portable chargers on planes?
Yes, in carry-on only (never checked luggage – TSA explicitly bans lithium batteries in checked bags). Most airlines allow chargers up to 100Wh (~27,000mAh). Chargers 100-160Wh need airline approval. Over 160Wh prohibited. Most travel chargers (10K-24K mAh) are well under the limit.
What’s the difference between USB-C and USB-C PD?
USB-C is the physical port. USB-C PD (Power Delivery) is a charging protocol that allows higher wattage (up to 100W) for charging laptops and tablets. A “USB-C PD” port can charge laptops; a regular USB-C port typically can’t. Look for “PD” specifically when buying adapters and chargers if you need to charge a laptop.

What’s the difference between USB-C and USB-C PD?
USB-C is the physical port. USB-C PD (Power Delivery) is a charging protocol that allows higher wattage (up to 100W) for charging laptops and tablets. A ‘USB-C PD’ port can charge laptops; a regular USB-C port typically can’t. Look for ‘PD’ specifically when buying adapters and chargers if you need to charge a laptop.
