Samsung Watch power bank

The TQTHL MP4 is a 2000mAh power bank designed for Samsung Galaxy Watch models from Active 2 through Watch 8, including Ultra and Pro variants. It also charges iPhone 15 and other USB-C phones via a built-in Type-C connector. The compact black unit attaches to a keychain for daily carry.

Upgrade from cable-only chargers

This 2-in-1 device replaces separate watch pucks and phone cables with a single magnetic dock and integrated Type-C plug. The jump is worth it when you want one pocket-sized accessory that tops up both a Galaxy Watch and a USB-C handset without carrying extra cords.

Check your devices before ordering

Verify your watch model appears in the supported list; Galaxy Watch S2, S3 and Active 1 have weaker magnetic attraction. Confirm your phone charges through a USB-C port, as no Lightning or Micro-USB adapter is included. The 2000mAh capacity suits top-ups rather than multiple full cycles.

Questions about this item

How does the built-in Type-C cable and magnetic watch pad fit in a pocket or bag?

The MP4 measures 40 by 42 by 15 mm and weighs very little, so the integrated cable tucks into the body and the magnetic pad lies flat on the key-ring loop.

What is the correct way to start charging a Galaxy Watch 6 Classic 47 mm and an iPhone 15 together?

Plug the Type-C end into the iPhone 15 first, then snap the watch onto the magnetic pad; the watch only draws power after the phone handshake finishes.

When should I replace the 2000mAh unit if it no longer tops up my Watch 5 Pro 45 mm?

When a full recharge of the power bank no longer delivers at least one complete watch charge, the internal cell has degraded past useful capacity.
