What it is

The Linearflux LithiumCard PRO is a 3000 mAh lithium power bank in a Titanium finish. It delivers 5 V DC at 3 A through integrated retractable charge and sync cables plus an extra USB auxiliary port. The NanoStik nanosuction pad lets it cling to a phone or tablet without adhesive. It suits anyone who wants a slim, all-in-one charger for daily carry.

What the extras change

Retractable cables remove the need to carry separate leads for charging and data sync. The auxiliary USB port lets a second device draw power from the same battery. The NanoStik pad replaces sticky mounts or clips so the bank stays attached during use and peels off cleanly. Together they turn the unit into a self-contained charging kit for iPhone, iPad, smartwatch or any USB device.

What to check first

Confirm your device charges at 5 V DC and can accept up to 3 A for fastest replenishment. Verify the retractable connector matches your port type before relying on it as your only cable. Ensure the NanoStik surface contacts a smooth, non-porous back panel; textured cases or curved edges may reduce grip. The 3000 mAh capacity is sized for a single phone top-up rather than multiple full cycles.

Questions about this item

Will the 3000 mAh lithium cell hold a full charge after hundreds of cycles?

The internal lithium cell is rated for 3000 mAh and will gradually lose capacity over many charge cycles; replacement is not user-serviceable.

What stops the 3 A output from running continuously?

Sustained 3 A delivery is limited by the 3000 mAh capacity and internal thermal protection, so output drops once the cell depletes or overheats.

Does the Titanium case get hot or make noise during all-day charging?

No fan is present; the aluminium Titanium shell dissipates heat silently, though it will feel warm during prolonged 3 A use.
