COMPATIBILITY
Our adapter can be used to charge or power:
a) USB-charged products such as iPhone, Samsung and other Android phones, smart watch and fitness tracker, tablet, power bank, camera, batteries set, headsets, etc;
b) small power device that supports dual (world-wide) voltage, which has “100-240V, 50/60Hz” printed on it*, such as phone or tablet charger, most laptops, etc.
* Some brands might use “110-230V”, “110/250V”, or "125/240V"a variation of similar range.

NOT A VOLTAGE CONVERTER
In the US and Canada, the standard AC outlets are 110-120V. In Europe and many other countries, they are 220-240V. Please note that our adapter does NOT convert voltage. Using single voltage device at incompatible voltage through our adapter is strictly prohibited, as such a practice will damage your device and lead to serious consequences like overheating, smoke, fire, or even explosion.
* Normally you will see “120V, 60Hz” and/or “household use only” on such devices. Some brands might use “117V”, “110-130V”, or a variation of similar number or range.
Need Check: Hair tools, CPAP, electric shavers and toothbrushes, etc.
NOT Allowed: Dyson products; Any appliance (hair dryer, steamer, etc) over 1600W, even if it is labeled as “dual voltage”.

REPLACEMENT OF THE FUSE
This adapter comes with 3 fuses - 1 at the center of the 3 prongs labeled with "FUSED", 2 extra spares in separate pouch.
Step 1: Pry open the fuse compartment cap ①, remove the working (broken) fuse ②, and replace it with the spare fuse.
Step 2: Align the new fuse with the two metal arms, and press the cap back in.
Note:
A blown fuse is the most common reason your adapter AC outlet stops working. If AC fails while USB ports still work, it is almost certain that the fuse is blown, especially if this happens after you use a high-power appliance like a hair dryer. The breaking capacity of the fuse is 13A.

APPENDIX - COMPATIBLE COUNTRIES & REGIONS 50+
Most countries in Europe, North America, and Australia have well-defined plug, socket, and voltage standards. On the other hand, many South American, Asian, and African countries adopt mixed standards, and some of them are incompatible, due to historical reasons. The voltage in some countries even differs from region to region. This makes it very hard for travelers to determine what kind of adapter (or voltage transformer) is needed for their trip. We made this list, to the best of our knowledge, to give you a general idea of what types of plugs or sockets are used in over 50 countries and regions. However, with so many areas in the world and ever-changing regulations, no single list could cover all areas and be absolutely accurate. We cannot guarantee the information provided here is error-free or up-to-date. You should not rely solely on the information in the list; it is still your responsibility to do more in-depth adapter research for your trip.
Please note that, if a foreign country mostly uses Type B socket (Example: Canada, Mexico), you will not need any travel adapter. If Type A is the standard in that country (Example: Japan) and you have a 2-prong device, you will not need an adapter; but if you have 3-prong devices, you will still need an adapter for your trip.
1. ✔= Our adapter can plug into the sockets in that country (Example: Germany, France, Italy, Spain, Switzerland etc.).
2. Partially = This country has more than one socket/plug standard. One of them belongs to the Type C family and works with our C321 adapter, but the other(s) is (are) Type A, B, D, G, I or M. You need to check with the place you are going to visit or stay the exact socket type they have. (Example: China, India, South Africa, Thailand, etc.).
3. × = This country only uses Type A, B, D, G, I or M socket and our adapter simply won't work in that country (Example: England, Australia, New Zealand, Swaziland, Lesotho, etc.). But again, for Type A/B countries, you might don’t need a travel adapter, especially if you only have 2-prong US device.
Warning: Our adapter is NOT a voltage converter or transformer. 220-240V voltages are highlighted in red, and you MUST make sure your device supports dual voltage (100-240V) before your trip. Epicka and all its related parties assume no liability for any damage, loss, or injury caused by using your device with an incompatible voltage through our adapter.
