Really nice charger. Metal made, look and feel is really good.
There are faster chargers, but still is recognized by phone as fast charge.
Works properly even with 2 phones connected.
This is the second time I bought this product, and that is because it worked amazingly on my car (Skoda Rapid), so decided to get it for a friend.
By doing so, discovered that it's not a universal plug, and in some cars, because of the big Window breaker tip, it wont make contact.
My friend's car is a Suzuki Swift and if you plug it directly, the tip doesn't reaches the bottom of the connector, so it wont work.
You can solve this issue easily by unscrewing the round tip (as you can see in the images), as the spring below will be able to touch the connector and pass close the connection.
Would give it a 4.5 star rating

Compact charger with useful information on battery status and amperage draw by plugged in devices. The video in the product page is for an alphawise charger, it does not apply to this item so don't hope it does 12V as that video shows. If 2 devices are connected, the display is harder to read but that is rarely the case for me. The light doesnt bleed on the edges and it doesnt draw attention in th dark. Quite decent.
