Age Verification

You must be 18 or over to purchase from this website. To comply with UK law on age-restricted nicotine products, we use 1Account, a secure third-party age verification service, to confirm your age at checkout. In most cases this check is completed automatically using the details you provide, and no extra steps are needed.

If 1Account can’t verify you automatically, you’ll be asked to choose one of three quick methods: a photo age estimation, an ID document scan (such as a driving licence or passport), or a credit card check. Once verified, your account is marked as over 18 so you shouldn’t need to verify again on future orders.

We cannot legally dispatch your order until age verification is complete. If your age is not verified within 5 days (when the verification link expires), your order will be refunded. For more information on how 1Account handles your data, please see their privacy policy at 1account.net.

Description

The Efest Pro C4 Battery Charger is a simple, cost-effective four-bay smart charger for 3.6V/3.7V cylindrical lithium-ion batteries, including popular 18650 and 26650 cells.
