High-capacity portable charger

Real-world charging headroom

The bank delivers 15 to 20 full smartphone charges or 5 to 8 tablet charges before it needs recharging. Five simultaneous outputs — two at 30W, two at 15W and one 20W USB-C — let you top up a phone, tablet, headphones, fan and speaker together. It cannot power laptops.

30W PD and QC 3.0 fast charging

Two 30W USB ports and one 20W USB-C port support PD and QC 3.0, pushing a compatible phone to 60 percent in 30 minutes. Recharging the bank itself takes roughly 7 hours via the 18W USB-C input. Multi-protection circuitry guards against overheating, overcurrent and short-circuits.

Questions about this item

Will the 70000 mAh ViewSonic BP1-70 charge my older phone that only takes a standard USB-A cable?

Yes. The power bank includes two 15 W USB-A ports alongside the USB-C outputs, so legacy devices charge at up to 15 W without an adapter.

How do I confirm the 30 W fast charge is active on my ViewSonic BP1-70 after I plug in?

The built-in LED digital display shows real-time output watts; when a compatible phone draws 30 W the readout will reflect that rate.

What cables come in the box with the ViewSonic BP1-70 and what must I supply myself?

The package includes the power bank only; you need to provide your own USB-C cable for 30 W input or output and any USB-A cables for the 15 W ports.
