Best Praise

+2 pts

“Last day for the Anker Nano 45w at Best Buy. It's discounted 50% selling today for $15. Also available on Amazon for $18. It's the perfect PPS charger for your Galaxy and Pixel phones. Price includes heavy gauge, 5 amp cable.”

Top Criticism

+14 pts

“>The database on the 45W Anker is not updateable, a charger you buy today will not recognize an iPhone 18. Seriously I love Anker but this product feels like such a reach. What does all this wizardry really get you a standard charger can't? It's like the studies on phones that have been limited to 80% charge their whole lives showing negligible battery life savings over others that just got charged to 100% every night. Or using a 5W charger over 20W. Just doesn't seem to amount to anything special in the end.”
