HOW TO FIX A SPOILT RECHARGEABLE FAN


When a rechargeable fan is spoilt from the inside its very easy to bypass the
problem and keep using the fan. All the fan needs to rotate is direct current
(DC) which is produced by a battery cell inside the fan. So when the whole
charging system of the fan spoils and the fan is not working anymore, just cut
out the wire coming from the rotating head and connect it directly to the
battery (i.e connect the negative wire or blue wire to the negative or blue side
of the battery, Do the same for the positive or red wire). Now the issue that'll
arise will be getting the battery to charge cos the battery will die eventually.
Now to charge the battery you can use the fan charger (IF ONLY IT HAS ITS OWN
BUCK BOOST CONVERTER OR POWER PACK AS IT IS CALLED, AND MAKE SURE THAT IT IS NOT
FAULTY) by cutting out the mouth that goes to the fan, then bring out the two
wires on the inside the red one is positive and the blue is negative by default,
but if yours doesn't have color you can determine which is which using a
galvanometer/voltmeter. Now do the same connection for the charger as you did
with the fan, i.e plugging positive to positive and negative to negative.
NOW IF YOUR FAN CHARGER IS AN ORDINARY WIRE AND DOES NOT HAVE POWER PACK OR IF
THE POWER PACK IS FAULTY. you can use laptop charger with a working power pack
to charge it on the following conditions.
1. You must find out the voltage rating of the power pack.
2. You must ensure that the voltage rating of the power pack is greater than the
voltage of the battery. The voltage rating of the power pack below is 19 volts.
3. You must ensure that the power pack rating is not more than 5 volts higher
than the battery voltage (i.e battery voltage4. If your fan has two batteries
make sure the sum of the voltages of the two batteries satisfies conditions 1,2,
and 3. And when connecting the batteries for charging connect it in series. 
The above conditions MUST be satisfied for the charging to work. If the voltage
rating of your battery is too high you could connect a resistor or any DC
appliance that'll lead to a voltage drop.

I cleaned my rechargeable fan and later on I wanted to plug it to charge, but it
keeps sparking anytime I plug it.

It would have been good if only this ur description can be shown practically.
I mean the connections... according to what you said. It's just like running the
same AC power connected to the battery into the fan as well.
Pls do well to describe series connection of the power pack to the battery then
the fan.
Thanks.

The charging point of my rechargeable fan appears to be the problem. If I buy
new charging cable it will work once and the fan will be fully charged. By the
time I want to recharge, it would have destroyed the charger. I keep buying new
chargers. How do I change the charging point
