3, available household 220 v charging
4, available at 12 v cigarette butts to recharge
5, and 7 is suitable for different transition joint inflatable products (including two quick connectors)
6, with the largest industry electric capacity: 4500 Mah, the cumulative effective charging time: 1 hour (moratorium on battery reply physical performance, many times to get the longest)
  instructions and matters needing attention:
1, will switch according to ON before the charging, charging pump into protection mode, cannot undertake air operations.
2, air pump, in use, there will be a small gas ran out from the switch and the edge of the gap, designed for decompression, belongs to the normal phenomenon, not a quality problem!
3, when air pump for inflatable products, disposable most atmospheric pressure available time for 20 minutes. After 20 minutes pressure decreases, suggested that the suspended for 10 minutes and then use (pressure back to normal after the suspension, can be used again for 15 minutes. If you want to get more output, atmospheric pressure can be suspended again after 10 minutes).
4, operating air pump to inflate cannot last more than 20 minutes, to avoid overheating and burning motor.
5, pump should flat when in use, do not tilt or, avoid noise affecting the service life of pump work!
6, should retain a small gas extraction, so that the inflatable products to adapt to the heat bilges cold shrink, prolong service life.


use skill : the product in a use to significantly lower air pressure, can suspend work about 10 minutes, leave the battery physical performance, then use again, pump will output the atmospheric pressure.(every pump output pressure decrease, can follow this operation, the maximum effective use of time).
