Authentic Samsung Micro-USB Charger

This genuine Samsung ETA3U30JBE adapter delivers 4.75V at 0.55A through a Micro-USB connector. It accepts a universal 100-240V input at 0.15A for worldwide travel use. The unit is tested for full functionality and includes protections against incorrect voltage, short circuit, and internal overheating. Minor cosmetic marks may be present on the body.

Suits owners of legacy Samsung devices

This charger fits older phones, headsets, or accessories that require exactly 4.75V via Micro-USB. It will not power modern hardware that needs 5V or higher current, nor does it support fast-charging protocols. Buyers who need more output current or a USB-C connector should look at a different adapter.

Fixed 4.75V 0.55A output specification

The single deciding specification is the fixed 4.75V 0.55A output rating. Your device must list this exact voltage and accept this current level to charge correctly and safely. Verify the required voltage on your original charger or device label before purchasing this model.

Questions about this item

What device connector does this 4.75V 0.55A charger need to work?

It requires a Micro-USB cable to connect the charger's output to your device's charging port.

Will this charger work with older phones that only draw 0.5A?

Yes, the 0.55A output safely supplies up to that current, so a 0.5A phone will charge normally.

How can I confirm the charger is delivering 4.75V after plugging it in?

The device should show a charging indicator; if it powers on and charges, the adapter is working as intended.
