What are the differences between Amazon Echo, Echo Dot, and Tap?

My answer to What are the differences between Amazon Echo, Echo Dot, and Tap?

Answer by Allen He:

Amazon Echo

Release date: 2015 in US, 2016 in UK.

Availability: Available in the US (Amazon US order page) / Available in UK (Amazon UK order page)

Price: $179 / £149

Dimensions: 235 mm x 83.5 mm x 83.5 mm

Weight: 1045 grams

Connectivity: Bluetooth and dual-band, dual-antenna Wi-Fi (MIMO)

Power: Plugs into a wall outlet

Audio: 360-degree sound (2.5 inch woofer and 2.0 inch tweeter)

Alexa: Yes (Always-on/always-listening/voice-activated)

Amazon Echo is ideal if you just want to have a stationary speaker that doubles as an always-on personal assistant. It'll provide you with room-filling audio that's sufficient for casual listening but it gets sort of tinny when turned up too much. If you're connected to Wi-Fi, you can ask it all sorts of questions and get it to control your stuff and it is available in the US and the UK.

Amazon Tap

Release date: 31 March 2016 for US

Availability: Available in the US (Amazon US order page)

Price: $129.99

Dimensions: 59 mm x 66 mm x 66 mm

Weight: 470 grams

Connectivity: Bluetooth and supports 802.11b, 802.11g, or 802.11n Wi-Fi

Power: Relies on a charging cradle (9 hours of playback)

Audio: 360-degree sound (dual 1.5-inch drivers and dual passive radiators)

Alexa: Yes (Not always-listening; Must touch mic button to access Alexa)

Amazon Tap is supposed to do all of that, including provide a similar sound experience, but it ditches the cord and uses a charging cradle in order to be portable. As it's not always plugged into power, always-on Alexa isn't available though. You have to push a mic button to access the service. Tap is therefore useful if you're going to the beach or are always on the go and it is only available to those in the US.

Amazon Dot

Release date: September 2016

Availability: Available in the US (Amazon US order page); available in the UK (Amazon UK order page)

Price: $49 / £49

Dimensions: 38 mm x 84 mm x 84 mm

Weight: 250 grams

Connectivity: Bluetooth and dual-band, dual-antenna Wi-Fi (MIMO)

Power: Plugs into a wall outlet

Audio: Voice-feedback only (Must be connected to external speakers)

Alexa: Yes (Always-on/always-listening/voice-activated)

Amazon Dot is just think of it as a little, always-on Alexa hub. It's not a speaker but works with your speakers. It will be available in six and 12 packs so you can ensure every room in your home has Alexa listening.

How many times can a 10000mAh rated power bank charge an iPhone 6/6S?

My answer to How many times can a 10000mAh rated power bank charge an iPhone 6/6S?

Answer by Allen He:

How many times can a 10000mAh power bank fully charge your iPhone 6/6s? Actually, this is a difficult question to answer.

The number of times a 10000mAh power bank can fully charge your device is relevant to 3 primary factors.

1.— What device you are charging with a 10000mAh power bank —

Generally speaking, a good rule of thumb is to divide the mAh of 10000mAh power bank by the mAh of your device battery.

So a 10000mAh power bank can “theoretically” charge an iPhone 4s plus from 1-100% 4.1 times (10000 / 1810 = 5.5). –iphone6/6s battery capacity is 1810 mAh.

Keep in mind: this is never 100% accurate as there still some other factors involved which will influence the charging times, which is always higher than what a 6000mAh power bank can practically give. Keep reading…

2.— What is the device doing while it is being charged —

It’s not strange to see the device charged, for example, by a 10000mAh power bank, while you’re still using the device. So is there any difference between using the device while it’s plugged into and leaving the device alone or on airplan mode while it’s charged? The answer is undoubtedly YES.

If you are watching a movie on your device while the 10000mAh power bank is charging it, more power drained from the 10000mAh power bank and meantime it seems that your device is never charged. That is because you’re taking the power more quickly than the 10000mAh charges your device.

If you leave your device alone or on airplane mode while charging, you will get more fully charges since the device is not taking much battery charge at all while the 10000mAh power bank is charging up the device.

3.— The charging cycles of the power bank 10000mAh —

More charging cycles the power bank gives, its capacity will reduce. Theoretically, the capacity will reduce to 80% after 300 charging cycles. If so, a 10000mAh power bank may have a 10000mAh capacity. This is also relevant to the temperature when you’re using your power bank. And this point I believe you could find out on the manual when you brought the power bank.

Tips: As you can see, this is a very difficult question to answer. But I hopefully the information given here will be helpful. And welcome all to comment below or share to Facebook and twitter for more charging tips.

What’s the best method to preserve wine after opening the bottle?

My answer to What's the best method to preserve wine after opening the bottle?

Answer by Allen He:

I bought a intelligent vacuum wine preserver to preserve an opened bottle of wine. I think it is the best method to preserver the opened red wine. Here i collect some features of the preserver after my several month use.

  1. the preserver can make a vacuum environment. You need charging the intelligent preserver to sustain the function. Usually after your fully charge it can use one day-2 days.
  2. the preserver can detect the temperature around the wine and you can set a reasonable temperature for the presence.
  3. the preserver can be used very easily and smartly.
