POWERBLOC Users Manual
USB Charging Input - Micro B USB jack plugs into side of case.Two
green LEDS will light when charging.
Charging LED goes out
when fully charged
Note: any 3.5mm OD, 1.5mm ID jack power supply of
4-15v 0.5-4A can be used as fast charger input.
Battery Depleted :Your phone will stop charging &
most phones will indicate USB power error when the
charger voltage drops below 5v & the charger battery
drops below 3v. Plug charger into charging source.
Fast Charging: Most smartphones, such as the Droid
Bionic or iPhone, can accept high USB charging rates
of up to 1.5A. This will normally charge a depleted
iPhone or 1400mah smartphone in 1 hour or less.
Note: charging case may get warm. This is normal.
iPhone4/4s: After charging phone, disconnect from
charger, or recharge POWERBLOC within 8 hours.
Iphone4/4s continue to draw significant power from
charger even when phone is switched off. Droid Bi-
onic does not draw significant power in off or standby.
Tips: If POWERBLOC is not going to be used for
over a week, unplug battery from charger (red connec-
tor). Battery will last for several years & retain charge
when unplugged.
Problem: Plugged in but charging LED not on &
voltage ok LED is on -leave 3.5mm jack plugged in.
Unplug from wall. Wait 30s or more. Plug back into
outlet. If charging light still does not come on, leave
plugged in for 1 hour, then repeat unplug, wait 30s,
replug. If battery is severely depleted, battery needs
slow pre-charge cycle. In pre-charge, charging light
does NOT come on.
Battery lifetime: Li-poly battery should last 2-3 years
with normal daily use. If repeatedly depleted to 3v,
lifetime will be shortened. Capacity will slowly de-
crease with age. Battery can be replaced - check our
website for replacement batteries.
12v Output Option: The POWERBLOC chargers have a
jumper selectable 12v ouput option. In fact by chang-
ing a resistor any regulated voltage from 3-15v & up
to 4A can be output.
