Sethruki T-1 5000mAh power bank Black

Pocket-sized power bank

The Sethruki T-1 is a 5000mAh lithium-polymer power bank with integrated cables for both iPhone and Android devices. Its credit-card footprint and 3.53-ounce weight make it practical for daily carry in a pocket or small bag. The unit delivers 5V at up to 2A through the built-in connectors, so there is no need to pack separate cords. It suits commuters and travellers who want a single, self-contained backup for one or two phones.

Sustained output and cycle life

The 2A maximum output is maintained until the cell reaches its lower voltage limit, avoiding the steep taper seen in smaller packs. A 5000mAh capacity typically yields one full charge for a modern flagship phone or nearly two for an older model like the iPhone 8. The manufacturer rates the cell for 500-plus recharge cycles before capacity drops noticeably, and the protection circuitry guards against over-charge, over-discharge, over-voltage, over-current and short circuits throughout that lifespan.

Input limits and air-travel compliance

Recharging the power bank itself uses a USB-C port at 5V 2A, taking roughly three hours from empty to full when a suitable adapter is used. Four LED indicators show the state of charge in 25-percent steps. The 5000mAh rating falls within the 100Wh international aviation limit, so the unit can be carried on board without special approval. No higher-voltage input protocols are supported, so recharge speed is capped by the 5V 2A specification.
