Tronsmart Presto 10400mAh USB-C/Type-C External Battery/Portable Charger/Power Bank with Quick Charge 3.0 Technology for iPhone, iPad, Samsung & more

This battery pack is great. No curved or wavy edges to waste space (unlike previous ones I've owned), a great amount of power for such a small box, you can take it on flights in China (it's 39.52Wh).The included cable is perfect too, fits in the case easily when folded in half, and because it's USB A -> C, you can use it to charge the battery pack, and also your USB C device. I haven't had to use another cable with it.

This product has server me really well for the month that ive used it so far.+Almost wall port charging speeds.+As someone who uses their nexus 6p enough to wash out the battery almost everyday before i make it home from work, I am impressed by the efficiency of the battery so far. It has lasted almost exactly how long it should if you consider 100% power efficiency.+Comes with a very useful carrying pouch which i can carry the necassary cables around in as well as the actual battery.-A bit large but that was expected.-No passthrough charging. You can't cahrge both a device and the battery at the same time.

The dealer is very reliable, the product is perfect without damages or imperfections. The power is very good, it's not so heavy and it's perfect to keep in your backpack or in your jacket. If Tronsmart added colour led to express the level of the charghe of the power bank. Anyway it does his work, I have a nexus 6P and the charging it's ok. As always, Amazon is perfect.

Bought this to charge my Nexus 5X in my locker at work. It charged my Nexus 5X from 30% to 100% in around 1 hour 30 minutes, from the usb type c port. Not just as quick as the wall charger but by no means is it slow.The chargers is well made and not too big or heavy. The charger also supports quick charge 3 for supported devices. Recommended.

I just wish this was smaller. Even if it had a smaller capacity. However, this is STILL the smallest type C charging bank on the market. Nothing else comes close. It also quick charges both ways. It fits in my pocket so I can't fault it. I highly recommend it.

Had the Tronsmart Presto 10400 for 2 months now and have used it regularly. Perfect...and does charge my Lumia 950 Windows phone very rapidly and more than three times over before it runs out of juice.Obvious good quality and very handy size. Thank you Tronsmart! Thank you In4dealz for prompt delivery!

Purchased this charger 6 months ago and used several occasions with out any issue.My Nexus 5X phone rapid charge with this battery pack and so far it have not let me down.Very compact and light weight for it's capacity, also comes with a very useful carrying pouch and charging cables.Excellent product and highly recommended for phones with USB Type C.

Superb piece of tech must have for those who need extra battery life on the go. I've charged 2 phones and a kindle fire and still had battery in reserve
