What this charger is

The zonbto 20W USB-C charger block delivers up to 20W of Power Delivery output through a single USB-C port. It accepts 100-240V input at 50/60Hz and offers three fixed voltage steps: 5V/3A, 9V/2.22A, and 12V/1.67A. The housing uses flame-retardant PC material and carries UL certification. No cable is included in the package.

Who it suits and who it does not

This charger suits owners of the listed Samsung Galaxy Tab models who need a compact, safety-certified wall adapter for home or travel. It also works with other USB-C devices that accept the stated PD profiles. Buyers who require multiple simultaneous ports, higher wattage for laptops, or an included cable should look at a different product.

Behaviour under sustained load

Integrated safeguards protect against overcharging, overheating and short-circuiting during continuous operation. The flame-proof PC shell resists heat buildup, allowing the brick to maintain its rated output without thermal throttling in normal indoor conditions. The 0.6A input draw remains stable across the full 100-240V range.

Questions about this item

Which USB-C cable do I need to use with this 20W charger block?

Any USB-C to USB-C cable rated for at least 3A will let the charger deliver its full 20W output.

Will this charger safely charge an older phone that only accepts 5V 1A?

Yes, the charger negotiates 5V 3A maximum, so a 5V 1A device will draw only the current it needs.

How can I confirm the charger is delivering fast charging to my Galaxy Tab?

The tablet’s lock screen or battery settings will show “Fast Charging” when the 9V 2.22A or 12V 1.67A profile is active.
