Local Dealer & Service

We have distributors in some countries or regions, so that you can receive our products faster and provide more timely and accurate after-sales service. Please contact us and we will recommend a suitable distributor to you.

7-day return policy

We have a 7-day return policy, which means you have 7 days from the date you receive the item to request a return.

To be eligible for a return, your item must be in the same condition as when you received it, guaranteed unused, with tags and original packaging. You will need to provide photos of the individual accessories of the item, as well as photos of the condition of the item’s packaging, and a receipt or proof of purchase.

To initiate a return, you can contact us at sales@100g.tech. If your return is accepted, we will give you an authorized return address and you will need to contact a courier to send it back yourself. Items sent back to us without first requesting a return will not be accepted.

You will need to send the item back to the address it came from, for example, if the item was sent from China (transit time approximately 20-30 days), you will need to send the item back to China; if the item was sent from a European warehouse (transit time approximately 3-5 days), you will need to send the item back to the European warehouse. You will also be responsible for the courier costs of sending the item back to the China or European warehouse.

Please note that items sent from China cannot be returned to a European warehouse as there are significant differences in how items are packaged and managed in the warehouse; similarly, items sent from a European warehouse cannot be returned to China.

Costs incurred in the 7-Day return process

Please note that the following charges may be incurred for returned items and will be deducted from refunds:

Refunds will be made less the cost of delivering the item to your home, which will be US$230 if the item was sent to you from China and US$45 if the item was sent to you from a European warehouse.

There will also be inspection and re-stocking fees. These fees are zero if returned to China and US$65 if returned to a European warehouse. These fees will be deducted from the amount returned.

You can always contact us at sales@100g.tech with any return questions.

Damages and issues

If you receive your parcel and find that the carton is broken or the contents of the parcel are damaged, please kindly don’t refuse to sign for the acceptance of the kit. (We will compensate if the items inside are damaged or lost, and make sure that you can eventually use the kit normally.)

Please cooperate in completing the following to facilitate our claim against the courier company:

1. Please take 3 or 4 photos of the outer box which must be shown the tracking number mark and broken areas clearly, please try to take photos from as many angles as possible.

2. Please confirm with the carrier that the goods arrived in a damaged box

3. If possible, claim directly from the courier company on the spot.

Exceptions / non-returnable items

Damaged batteries are hazardous materials that cannot be returned. Please get in touch if you have questions or concerns about your specific item.

Unfortunately, we cannot accept returns on sale items or gift cards.


The fastest way to ensure you get what you want is to order the correct item you need and return the item you have. Alternately, if time allows, once the return is accepted and you receive the credit notification, make a separate purchase for the new item.


We will notify you once we’ve received and inspected your return, and let you know if the refund was approved or not. If approved, you’ll be automatically refunded on your original payment method. Please remember it can take some time for your bank or credit card company to process and post the refund too.
