Frequently Asked Questions
Is this charger safe to use in hotel rooms and rental properties?
Yes. It is ETL certified with overvoltage, overcurrent, and temperature control, and it accepts the universal 120V North American outlet standard found in hotels, Airbnbs, and rental cars. It is also compact enough to pack in a carry-on without taking up outlet space from other guests.
Will one cube be enough for a multi-device traveler or do I need more?
The dual-port design lets you charge a phone and a pair of earbuds, a phone and a tablet, or a phone and a watch charger at the same time from a single wall outlet. For most solo travelers one cube is enough; for couples or families, the 4-pack is the better value.
Does it work in countries with 220V outlets or do I need a converter?
The 2-pin Type A North American connector is rated for 120V input, which is the standard in the US, Canada, Mexico, and Japan. For 220V regions you will need a plug adapter, not a voltage converter, but the charger itself does not support 220V input directly.
Is the plug compatible with the loose outlets often found in older hotels?
The prongs are a standard 2-pin Type A North American blade design that fits standard NEMA 1-15 outlets. In very old hotels with worn outlets, the snug fit of a quality block is actually safer than a loose-fitting cheap brick that can partially dislodge.
Can I leave it plugged in at an Airbnb without worrying about power surges?
The ETL certification includes overvoltage and overcurrent protection, so unexpected power fluctuations in older rental properties are handled at the chip level. Still, for high-value electronics in storm-prone areas, a surge protector strip between the wall and the block is a reasonable extra precaution.
How does a 4-pack compare to buying four chargers separately for a family trip?
A 4-pack drops the per-unit cost well below single OEM bricks, so you can outfit a family of four with matching chargers for less than the cost of two name-brand 20W blocks. Each person gets their own color so there is no fighting over outlets in the hotel room.
Is this better than bringing a power strip on a trip?
For most travelers, one charger per person replaces the need for a power strip entirely. A power strip is bulky, often flagged at airport security, and adds weight. Two-port blocks distributed across the room's existing outlets are a cleaner, lighter solution.
Will it fit in a carry-on liquids bag or personal item without taking much space?
A single cube is roughly the size of a small matchbox and weighs under 2 ounces. The full 4-pack is still smaller than a deck of cards and adds negligible weight to a backpack, weekender, or carry-on. It goes through airport security with no restrictions.
Can I use it to charge a laptop in a hotel room?
It delivers 20W via USB-C PD, which is enough to fast-charge a phone, an iPad, AirPods, and most e-readers at full speed. It will charge a MacBook Air or small USB-C laptop but only at a slow trickle, so it is not a replacement for a dedicated laptop brick.
Is this a good gift for someone who travels frequently for work?
Yes. Frequent business travelers often deal with dead phones between flights, hotels with too few outlets, and rental cars without USB-C ports. A compact 20W dual-port block solves all three problems and is small enough to live permanently in a carry-on.
Does it work in airport outlets and gate charging stations?
Yes. The 2-pin Type A plug fits the standard outlets at US airport gates, in terminals, and in most airline lounges. The compact form factor is especially valuable at crowded gate areas where a large brick can block adjacent outlets.
Can I leave it plugged in 24/7 at a vacation rental without fire risk?
The ETL certification specifically covers continuous-use charging scenarios, and the temperature control circuitry prevents the block from overheating even when left plugged in for days. It is designed for the kind of always-on use that travelers and remote workers expect.
How does it compare to a single-port travel charger?
Single-port travel chargers force you to choose between your phone and your earbuds, or carry a second block. A dual-port block eliminates that choice and still fits in the same pocket of a backpack, making it strictly better for almost every travel scenario.
Will it charge my phone fast enough to be useful during a short layover?
The 20W USB-C PD output reaches roughly 59% on a modern iPhone in 30 minutes, which is more than enough to make a meaningful dent during a typical 45 to 90 minute layover. It is one of the fastest charging speeds available without stepping up to a laptop brick.
Is it worth buying the 4-pack if I am a solo traveler?
A solo traveler can still benefit from the 4-pack: keep one in your carry-on, one in your checked bag, one at home, and one at the office. The per-unit cost is low enough that even with one or two extras stored as backups, the value is better than buying singles.
What happens if I lose one of the four cubes on a trip?
Because the 4-pack uses a single shared color and form factor, you can replace a lost cube with any single unit from the same product line. You are not locked into a specific batch or color, so a lost or forgotten charger is a small inconvenience rather than a full repurchase.
How do I set up the charger for the first time?
Plug the block into any standard 120V North American wall outlet or power strip. Connect your device's USB-C or USB-A cable to the matching port on the block, then plug the other end into your phone, tablet, or earbuds. Charging begins automatically within a second or two, with no pairing, app, or account required.
Can both ports charge at full speed at the same time?
Yes. The USB-C PD port delivers up to 20W and the USB-A port delivers up to 18W simultaneously, so you can fast-charge an iPhone on the USB-C port while still powering an older device or accessory on the USB-A port. Total combined output is enough for two phones to charge at near-maximum speed.
How do I know if my device is actually fast-charging?
On an iPhone, you will see a small 'fast charging' notification on the lock screen when the 20W USB-C PD port is actively delivering high-speed power. On Android, the battery icon will often show a double lightning bolt or 'fast charging' label. If neither indicator appears, swap to a higher-rated USB-C cable and confirm the device supports USB-C PD.
Does this charger work with iPhone 17 and the latest Galaxy and Pixel phones?
Yes. The 20W USB-C PD output is the standard fast-charging protocol for iPhone 8 through iPhone 17, Galaxy S20 through S25, Pixel 6 through 9, and most current iPad and AirPods models. The USB-A port supports older devices and accessories that use a standard USB-A cable.
Will this work with my older iPhone 5, 6, 7, or original AirPods?
Yes. Use a USB-A to Lightning cable for older iPhones and plug into the 18W USB-A port. The charger is backward compatible with every iPhone generation that uses a Lightning or USB-C cable, as well as all AirPods cases that charge via Lightning or USB-C.
What exactly is in the box when I order the 4-pack?
You receive four charging blocks in the color and configuration you select. Each block is a complete, ready-to-use charger with no cables included, so you use the USB-C and USB-A cables you already own. There is no separate power brick, adapter, or accessory required.
Do I need to buy USB-C cables separately?
Yes, the block itself does not include cables. Most modern phones ship with a USB-C or USB-C to Lightning cable in the box, and those work directly. If you need extras, any USB-C cable rated for 3A or higher will support full 20W fast charging.
How long will this charger last with daily use?
The internal components are rated for years of daily use under normal conditions, and the ETL certification covers long-term reliability testing. Most users get 3 to 5+ years of use before any output degradation, which is comparable to or longer than the typical OEM charger that ships with a phone.
Is it normal for the block to feel slightly warm while charging?
Yes, a slight warmth is normal and expected, especially when both ports are in use or the connected device is fast-charging. The temperature control circuitry keeps the internal components well within their safe operating range, and the block should never feel hot to the touch.
What is the difference between a USB-C PD charger and a regular USB charger?
A regular USB-A charger typically delivers 5W to 12W, which is the slow stock brick that ships with most older iPhones. A USB-C PD (Power Delivery) charger negotiates with the device to deliver up to 20W, which charges a modern phone 3x faster and reaches roughly 59% on an iPhone in 30 minutes versus about 17% on a 5W brick.
