Press the charge level check button, and the set of lights corresponding to the
current charge level will begin to flash. When the PowerPack is completely drained
and needs to be recharged, the lights will stay off. ●Recharge your PowerPack
A quality charge cable with a USB-C connector on one end and a USB-A or USB-C
on the other end can be used. Plug the USB-C connector of the cable into the
PowerPack’s input (middle) port and the other connector into the matching port
of a USB power adapter. The LED indicator lights will flash and then stay on solid
one by one as the charging progresses.
For a 20,000 mAh battery pack like the PowerPack 20K Pro, it is crucial that the
battery gets electricity as fast as possible during recharge, so that it can be ready
for the next use in no time. A more powerful charger with a higher rated wattage
(18W+) is strongly recommended. The PowerPack 20K Pro is designed to recharge
via USB PD or Quick Charge fast-charging power adapters as well as via
conventional power plug. Here are some suggested power adapters for recharging
the PowerPack:�
MacBook (2015 or later), MacBook Pro (2016 or later) stock Apple USB-C power
adapter (29W, 30W, 61W, or 87W)
Google Pixelbook USB-C power adapter (45W)
ZMI PowerPlug Turbo USB-C charger (45W)
Google Pixel USB-C charging plug (18W)
●Factory reset
The PowerPack is designed to safeguard against short-circuiting by entering a
temporary, protective mode, waiting to be reset. To reset, connect the PowerPack to
an AC/wall adapter via a quality charging cable and plug the AC adapter into a wall
outlet; unplug and replug the PowerPack’s side of the cable while leaving the AC
adapter plugged in the outlet. Short-circuiting on a port can sometimes result from
using a frayed/damaged charging cord. To avoid the protective mode being triggered
again, it is strongly suggested that you replace your frayed/damaged cord ASAP.

on the other end can be used. Plug the USB-C connector of the cable into the
PowerPack’s input (middle) port and the other connector into the matching port
of a USB power adapter. The LED indicator lights will flash and then stay on solid
one by one as the charging progresses.
For a 20,000 mAh battery pack like the PowerPack 20K Pro, it is crucial that the
battery gets electricity as fast as possible during recharge, so that it can be ready
for the next use in no time. A more powerful charger with a higher rated wattage
(18W+) is strongly recommended. The PowerPack 20K Pro is designed to recharge
via USB PD or Quick Charge fast-charging power adapters as well as via
conventional power plug. Here are some suggested power adapters for recharging
the PowerPack:�
MacBook (2015 or later), MacBook Pro (2016 or later) stock Apple USB-C power
adapter (29W, 30W, 61W, or 87W)
Google Pixelbook USB-C power adapter (45W)
ZMI PowerPlug Turbo USB-C charger (45W)
Google Pixel USB-C charging plug (18W)
●Factory reset
The PowerPack is designed to safeguard against short-circuiting by entering a
temporary, protective mode, waiting to be reset. To reset, connect the PowerPack to
an AC/wall adapter via a quality charging cable and plug the AC adapter into a wall
outlet; unplug and replug the PowerPack’s side of the cable while leaving the AC
adapter plugged in the outlet. Short-circuiting on a port can sometimes result from
using a frayed/damaged charging cord. To avoid the protective mode being triggered
again, it is strongly suggested that you replace your frayed/damaged cord ASAP.

FCC
This device complies with Part 15 of the FCC Rules. Operation is subject to the
following two conditions:
(1) This device may not cause harmful interference, and
(2) this device must accept any interference received, including interference that may
cause undesired operation.
●Check the charge level of your PowerPack
For FAQs and more information, please visit:
zmiusa. com/support
@zmiusa
@zmiusa
@zmiusacorp
Press the charge level check button, and the set of lights corresponding to the
current charge level will begin to flash. When the PowerPack is completely drained
and needs to be recharged, the lights will stay off. ●Recharge your PowerPack
A quality charge cable with a USB-C connector on one end and a USB-A or USB-C
on the other end can be used. Plug the USB-C connector of the cable into the
PowerPack’s input (middle) port and the other connector into the matching port
of a USB power adapter. The LED indicator lights will flash and then stay on solid
one by one as the charging progresses.
For a 20,000 mAh battery pack like the PowerPack 20K Pro, it is crucial that the
battery gets electricity as fast as possible during recharge, so that it can be ready
for the next use in no time. A more powerful charger with a higher rated wattage
(18W+) is strongly recommended. The PowerPack 20K Pro is designed to recharge
via USB PD or Quick Charge fast-charging power adapters as well as via
conventional power plug. Here are some suggested power adapters for recharging
the PowerPack:�
MacBook (2015 or later), MacBook Pro (2016 or later) stock Apple USB-C power
adapter (29W, 30W, 61W, or 87W)
Google Pixelbook USB-C power adapter (45W)
ZMI PowerPlug Turbo USB-C charger (45W)
Google Pixel USB-C charging plug (18W)
●Factory reset
The PowerPack is designed to safeguard against short-circuiting by entering a
temporary, protective mode, waiting to be reset. To reset, connect the PowerPack to
an AC/wall adapter via a quality charging cable and plug the AC adapter into a wall
outlet; unplug and replug the PowerPack’s side of the cable while leaving the AC
adapter plugged in the outlet. Short-circuiting on a port can sometimes result from
using a frayed/damaged charging cord. To avoid the protective mode being triggered
again, it is strongly suggested that you replace your frayed/damaged cord ASAP.

A quality charge cable with a USB-C connector on one end and a USB-A or USB-C
on the other end can be used. Plug the USB-C connector of the cable into the
PowerPack’s input (middle) port and the other connector into the matching port
of a USB power adapter. The LED indicator lights will flash and then stay on solid
one by one as the charging progresses.
For a 20,000 mAh battery pack like the PowerPack 20K Pro, it is crucial that the
battery gets electricity as fast as possible during recharge, so that it can be ready
for the next use in no time. A more powerful charger with a higher rated wattage
(18W+) is strongly recommended. The PowerPack 20K Pro is designed to recharge
via USB PD or Quick Charge fast-charging power adapters as well as via
conventional power plug. Here are some suggested power adapters for recharging
the PowerPack:�
MacBook (2015 or later), MacBook Pro (2016 or later) stock Apple USB-C power
adapter (29W, 30W, 61W, or 87W)
Google Pixelbook USB-C power adapter (45W)
ZMI PowerPlug Turbo USB-C charger (45W)
Google Pixel USB-C charging plug (18W)
●Factory reset
The PowerPack is designed to safeguard against short-circuiting by entering a
temporary, protective mode, waiting to be reset. To reset, connect the PowerPack to
an AC/wall adapter via a quality charging cable and plug the AC adapter into a wall
outlet; unplug and replug the PowerPack’s side of the cable while leaving the AC
adapter plugged in the outlet. Short-circuiting on a port can sometimes result from
using a frayed/damaged charging cord. To avoid the protective mode being triggered
again, it is strongly suggested that you replace your frayed/damaged cord ASAP.
