4. Function & Usage
Charge
Attention: When charging, the model WTEL1556A 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 WTEL1556A directly. Or use charging tips to charge. Charging indicator. Status: The indicator in RED when charging, in GREEN when full charge.
Discharge
Charging and discharging simultaneously. the output of WTEL1556A is as per charging voltage, not as per fixed voltage. Have to choose suitable voltage when charging.
Normal discharging.
Output when not charging, have to make sure the “optional switch” to the side of “VOL”. Press the button “VOL/ CHECK”, the indicator will show output voltage, after choosing, make sure the “ optional switch” to the side of “CHECK”. To connect LOADING then natural output.
Attention: When low voltage, the indicator will flash and means low voltage, will power off soon.
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.
Capacity checking
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% |
