For phone and small-device charging, start by comparing UA27, UA36A or UA8A; for a USB-C laptop, compare its input requirement with UA15 and the exact shared-output table. UA27 specifies up to 35W from its designated USB-C port; UA36A and UA8A are 70W-labelled models; UA15 lists 120W total USB and up to 100W on USB-C1 in the applicable single-port mode. Check destination sockets and appliance inputs before buying: plug conversion and voltage conversion are separate.
Which MOMAX travel adapters are currently listed?
Everything Store's travel adapter range lists the models below. The figures are MOMAX's published limits, not charging results measured by this store. Select the exact configuration on its product page and check the current HKD offer.
| Listed model | USB and AC configuration | Published USB limits to compare |
|---|---|---|
| 1-World² Mini, UA27 | 5 USB ports and 2 AC sockets | Up to 35W from the specified USB-C port; individual limits are lower when ports are shared |
| 1-World² Pocket, UA36A | 2 USB-C ports, 2 USB-A ports and 2 AC sockets | The model is labelled up to 70W; check the selected port and combined-output table |
| 1-World, UA8A | 5 USB ports and 1 travel AC socket | Up to 70W from the specified USB-C output; MOMAX specifies lower allocations when ports are shared |
| 1-World, UA15 | 3 USB-C ports, 1 USB-A port and 1 travel AC socket | 120W total USB output; USB-C1 is labelled up to 100W in the applicable single-port mode |
Will the plug fit your destination?
Check socket types and supply conditions at every stop, including overnight transit stops. Compare them with the selected model's plug positions, AC input ratings and instructions. A broad country count advertised by a manufacturer does not mean every socket or appliance is supported. A travel adapter changes the physical plug connection; do not assume it converts mains voltage for an appliance with a different input-voltage requirement.
Do not use a plug that cannot be inserted securely. When connecting AC appliances in particular, follow the adapter's rated current and the appliance label. See Hong Kong EMSD's travel adapter guidance for precautions.
How much USB power do you need for one device or several?
List each device's charging-input requirements first. A model's maximum wattage does not mean every port can deliver that figure simultaneously. For example, MOMAX lists UA15 at 120W total USB output and USB-C1 at up to 100W in single-port specifications; power is allocated differently when all 4 ports are used. UA27's specified USB-C output is up to 35W, with less available to that port in combined modes. Check the manufacturer's table for your intended combination.
For a phone and a small USB device, start by comparing the compact UA27 or UA36A. For a laptop, check its USB-C input requirement against the adapter's single-port and shared-port figures. UA15's higher published output may help, but headline wattage alone does not prove laptop compatibility. If travel plug pins are unnecessary, browse the chargers; for use away from a socket, browse the power banks.
What should you confirm before checkout?
- The destination's sockets, voltage, current and frequency, together with adapter and appliance labels.
- The selected model's AC socket arrangement and actual USB port configuration.
- Each port's individual output and the manufacturer's allocation when all devices are connected.
- The selected colour or configuration, current stock and the HKD price on the product page.
MOMAX travel adapter buying questions
Should I choose 35W, 70W or 120W?
Check each device first. UA27 offers up to 35W from its specified USB-C output. Compare UA36A or UA8A when you need their 70W-listed single-port mode. For a laptop, compare its USB-C input against UA15: 120W is total USB output, while USB-C1 is up to 100W in its stated single-port mode. Shared-port allocations differ.
Does it convert voltage for a hair dryer?
Do not treat a travel plug adapter as a voltage converter. Compare the appliance input label, local mains supply and the adapter's AC ratings. Use the manufacturer instructions and EMSD guidance linked below.
Where can I buy the exact model in Hong Kong?
Use the model links in the table, or compare the current travel adapters. Confirm the selected SKU, current HKD price and stock. SF Express Hong Kong delivery is free, with an estimated 2–5 business days.
For portable power during the trip, read the power-bank flight-rules guide before packing.
