Power banks are usually meant to give your phone a quick boost when you are away from a charger. The UBON PB-SX701 Bunker Series takes a different approach. With a huge 60,000mAh battery, it is designed more as a backup power source for homes, travel and emergencies than as an everyday pocket accessory.
The biggest attraction is its capacity. UBON says the power bank can charge smartphones and other USB-powered devices multiple times, making it useful during long power cuts, road trips or camping. For an ordinary user, this means less worry about finding a power socket when electricity is unavailable for several hours.
Charging is reasonably fast, with up to 22.5W output. The power bank supports both power delivery (PD) and quick charge (QC), giving users flexibility across compatible devices. Its multiple output ports also make it practical for charging more than one USB device, although actual charging speeds will depend on the device and port combination being used.
One of its most useful features is the digital battery display. Instead of relying on a few indicator lights, users can see the remaining charge level more precisely. This is particularly helpful with a power bank of this size, as running out of power unexpectedly defeats its purpose as an emergency backup.
The PB-SX701 also goes beyond charging. It has a built-in high-beam emergency torch and an ambient light panel. During a blackout, these can be genuinely useful, allowing the power bank to serve as both a backup battery and an emergency light. For camping or a roadside emergency, having both functions in one device can reduce the number of gadgets you need to carry.
There is, however, a clear trade-off. A 60,000mAh power bank is considerably larger and heavier than the compact models people normally carry in a bag. It is therefore better kept at home, in a car or in an emergency kit rather than carried around every day.
At ₹9,990, the PB-SX701 is not a casual purchase for someone who only needs occasional phone charging. Its appeal lies in its enormous capacity and added emergency features. For households facing prolonged power cuts, frequent travellers or outdoor users, it is a practical backup device that puts reliability ahead of portability.
