  • Ultra-compact 3.6×1.9×0.66 in design fits any pocket

Portable Power for Apple Watch

The ViewSonic P16 is a 2500mAh magnetic wireless charger built for Apple Watch Series 3 through Ultra 3. Its pocket-sized form factor and integrated battery make it practical for travel, camping, RV trips and daily commutes where wall outlets are unavailable.

Cable-Free Charging With Built-In Cable

A USB-C cable is permanently attached and doubles as a keychain loop, an input for recharging the power bank and an output for wired devices. Strong magnets auto-align the watch to the charging surface, starting the session instantly without loose cords or precise placement.

2500mAh Capacity Decides Suitability

The internal battery delivers roughly two full charges for an Apple Watch Ultra 13 or up to four for SE and Series models. Buyers needing more cycles between recharges or support for non-Apple wearables will find the capacity and compatibility insufficient.

Questions about this item

How many times can the 2500mAh battery recharge my Apple Watch Ultra 13 before it needs recharging itself?

The built-in 2500mAh battery delivers up to two full charges for an Apple Watch Ultra 13 before the power bank requires recharging via its USB-C port.

What limits continuous charging performance when the power bank is used all day?

The 2.5-watt output at 5 volts and 2 amps sets the maximum charging rate, so sustained use is limited by this fixed power delivery rather than thermal throttling.

Does the charger generate noticeable heat or noise during extended daily use?

The multi-protection safety chip guards against overheating and overcurrent, and with no moving parts the unit runs silently while maintaining stable temperatures during all-day operation.
