最后，有人可能警告過你，便宜的第三方充電器會毀掉你的手機(jī)。這有部分是真的：很多充電器——特別是在網(wǎng)上出售的便宜樣機(jī)，甚至是本地購物中心小攤里賣的充電器——做工很糟，或者使用質(zhì)量低劣的元件。質(zhì)量差的充電器不僅會弄壞你的手機(jī)，而且還會漏電，讓你受傷。所以如果要更換充電器，或多買一個備用，一定要選擇可靠的生產(chǎn)廠家。

Finally, you may see warnings that a cheap third-party charger could damage your phone. There’s some truth here: Many chargers — especially budget models sold online, or even at your local shopping mall kiosk — are poorly made, or use low-quality components. A poorly made charger can not only damage your phone, but could also hurt you by exposing you to dangerous currents. So if you’re replacing your phone’s AC adapter, or buying an extra, stick with a reputable vendor.
