2 Way Charger,
Verified Purchase(What is this?)
This review is from: Two-Way 12V DC Car Charger Cigar Cigarette Lighter Double Power Adapter Socket Splitter (Wireless Phone Accessory)
As a long distance driver I have on occasion found that either my mobile or Sat Nav battery has gone low or switched off and I had to make a choice, lose contact with my employer or switch oof the Sat Nav and start reading maps whilst the affected battery recharged. With this device I no longer have that problem as I can operate both at the same time.
