More About the XUNDD XDPB-029

Having an integrated USB-C cable attached directly to the body changes how you carry a power bank day to day. You won't need to double-check your pocket or bag for a loose cable before heading out, making quick wired top-ups much simpler when you're moving between places.

The clear tempered glass panel lets you look right at the internal board while giving you a precise percentage readout of remaining power. This digital display is far more helpful than standard 4-dot LED indicators, which leave you guessing whether four dots means 76% or 100% capacity.

Magnetic strength is another point where the XDPB-029 holds its ground. The upgraded 1800Gs magnetic array provides a firm snap against iPhone 12 through 17 series devices. At 15.7mm thick and 186g, it sits comfortably against the back of your phone without feeling overly cumbersome during active use.

As with all portable batteries, actual power delivery differs from raw cell capacity. The internal battery holds 10,000mAh, while the rated output capacity is 6,000mAh at standard conversion voltages. Wireless charging naturally generates extra heat and experiences higher power loss than a direct wired connection, so expect around 1.2 to 1.5 full charges on modern smartphones when charging wirelessly.

Specifications

The 10,000mAh figure indicates internal battery cell capacity. Usable energy output (6,000mAh rated) is lower due to standard 5V voltage conversion, with additional energy loss occurring during wireless charging.
