PocketJuice 15000 mAh portable charger

The PocketJuice 15000 mAh power bank is a compact backup battery for phones and other USB-enabled devices. Its 15000 mAh cell stores enough energy for several full phone charges during travel or long days away from a wall outlet. The black finish resists visible scuffs in a bag or pocket. It suits anyone who needs reliable extra runtime without carrying a bulky adapter.

Capacity and headroom

A 15000 mAh rating delivers multiple complete charges for typical smartphones before the power bank itself needs recharging. Tablets and larger devices will draw the reserve down faster, so expect fewer full cycles. The unit has no built-in cables, so you must supply your own USB leads for each device. It is not intended for laptops or high-draw accessories that exceed standard USB output limits.

Thermals noise and power draw

The charger operates silently with no moving parts or fans. Normal use produces only slight warmth from the internal cells and regulation circuitry. Power draw while recharging the bank matches standard USB input rates and does not require a specialised adapter. Heat stays low during both charging and discharging cycles under typical loads.
