4. Function & Usage
1).Charge
Attention: When charging, the model WTEL1556B will output power directly to LOAD as per charging
voltage. (namely charging and discharging simultaneously). If the charging voltage is higher or lower
than LOAD rating voltage, it may damage LOAD. Therefore, when LOAD rating voltage is not equal to
charging voltage, cannot connect with LOAD when charging.
When choose the AC adaptor of 15-25W, can charge WTEL1556B directly. Or use charging tips to charge.
Charging indicator. Status: The indicator in RED when charging, in GREEN when full charge.
2).Discharge

Charging and discharging simultaneously. the output of WTEL1556B is as per charging voltage, not as per
voltage. Have to choose suitable voltage when charging.
5.Normal discharging.
Output when not charging, have to make sure the optional switch to the side of VOL. Press the button
CHECK, the indicator will show output voltage, after choosing, make sure the optional switch to the sid
CHECK. To connect LOAD then natural output.
Attention: When low voltage, the indicator will flash and means low voltage, will power off soon.
6.USB
Output automatically: USB output continuously when charging and discharging.
Output by hand: when not charging and discharging, make sure the optional switch to the side of
check, press the button vol/ check, USB start to output. If the USB LOAD is little(about 800mA), USB
will power off automatically.
7.Charging Current:2.5A MAX.
Make Optional switch to the side of check, press the button VOL/ CHECK. Will show capacity. The
capacity chart is as below.
Capacity/output indicator Capacity
1 LED blinks, 0≤RP≤10%
1 LED lights on 10%≤RP≤30%
2 LED lights on, 30%≤RP≤50%
3 LED lights on, 50%≤RP≤70%
4 LED lights on, 70%≤RP≤90%
5 LED lights on, 90% ≤RP≤100%
8. SafetyCertification
