What's up with the tag, “Another Big Dog”? Does that mean that this plays second-fiddle to the top Power Bank on the market? No, we actually had a hard time deciding what the top Power Bank in India is. We went with the Syska 20000 mAh Power Bank as our premium choice. However, we cannot really argue that the Syska is any better than the Ambrane 20000mAh Lithium Polymer Power Bank. Thus, we dedicate a separate review for this giant in the realm of Power Banks, for this Big Dog.

We have already reviewed the top Power Banks and today we bring you the already mentioned Big Dog of Power Banks, the Ambrane 20000mAh Lithium Polymer Power Bank.

Who Needs This Power Bank?

Anyone who wants simply the best quality product surely needs to check this Power Bank out. The Ambrane brand produces no shortage of great Power Banks. Check out our review of four of the top Ambrane Power Banks.

With its superior features, the Ambrane 20000mAh Lithium Polymer Power Bank truly gives the best of the best Power Banks in India a run for their money, and many may rightfully argue for its place at the top of the food chain. If you want a solid Power Bank which can withstand some (unintentional) bumps and bruises, is stylistic and can charge two devices at the same time multiple times, then look no further than this Power Bank. We recently reviewed the Ambrane P-1310 which too was a beast but nothing compared to this big dog!

Why Do We Recommend This Product?

Good products are the only ones we ever review. If you ever see a product review on this website, know that you can definitely buy this and not get disappointed. However, everyone has different tastes, and that is why we try to offer a range of good options that are aimed at suiting all kinds of people. Still, if you want to know for yourself what criteria you should look out for when buying a Power Bank, then go through the following points.

Battery Capacity

The battery capacity of a Power Bank is written in its very name. As a rule of thumb, 1,000 mAh of battery capacity depletes in an hour of usage. Thus, that means that you can have 20 hours of extra usage with a 20,000 mAh Power Bank like the Stylo-20K. However, there is some leakage of power at work. Don't expect a 100% transfer rate while charging. Therefore, assume that you can get 15 hours of extra usage out of a phone with this Power Bank. That's like being able to use your iPhone 6 times over.

Price

A very good deal, indeed. BUT, when it comes to Power Banks, battery power is inversely proportional to its ease of portability. This follows that an expensive Power Bank like this is not going to be on the budget of many people who are only looking for a plain power bank.

Ease of Portability

The best use of a Power Bank, according to us, is if you can easily carry it while on the go. When at home, you can simply charge your phone with a wall charger. No Power Banks required there. It is only when you are travelling, sitting in a bus or a train, for example, when those extra couple of hours provided by a Power Bank REALLY helps. Thus, if you can't comfortably carry your Power Bank in your pocket, and instead have to carry it inside a bag, it proves a hassle. Unfortunately, this product does not score much high on portability.

One word of advice: if you simply want a Power Bank which can charge your phone well and doesn't have many extra features, go buy a cheap one. We have got you covered here with our review on some Power Banks Under 1000 INR! Then again, how many Power Banks do you buy anyway? Why not get a high-end one like the Stylo-20K, an undoubtedly big dog in the game.

Usability

Ease of maintenance and comfort of usage should be looked at when considering any product. With both USB and type C ports, not to mention its safe mechanism of preventing overcharging, the Stylo-20K scores incredibly high on usability!

Appearance

We have reviewed many Power Banks, and it is with a sad heart that we admit that most of them are quite bland and not stylish. However, this product caught our eye with its unique engraving of its battery capacity on its back. Its appearance is cool yet classy.

What Are The Features Of This Product?

As the name reveals, this is a 20,000 mAh battery capacity Power Bank, meaning it can handle charging a phone multiple times. Let us correct that: it can not only charge a phone more than once, but it can also charge two phones (or other electronic devices) multiple times. That's right: this Power Bank has Dual Ports.

The “20000” engraved on the Power Bank is stylish, if we say so ourselves. We verified that the material used for engraving it is made of strong ABS plastic material. This means that it can handle its fair share of scratches and not have anything to show for them. Yeah, we did try and scar it (things we do for reviews!).

We can attest to the Power Bank's ease of maintenance through first-hand use (yeah, some of us use this very product). For example, there is a Feather Touch Button on the Power Bank which signals the power status of the battery — shows how much battery is left. Moreover, it prevents overcharging and short circuits. This means that if you leave the Power Bank on charge for whole days even, don't feel sorry for its battery as it will not bloat with all the extra power. What's more, the Power Bank has dual input options. Both USB and type C Ports are supported. Isn't that a treat?

As for how long it requires to fully charge the device, we have verified that it requires 10 hours. That is, unfortunately, a long time, and is a longer time than our number one recommendation. However, you should keep in mind that Power Banks don't need to be charged daily unless there's always one or two phones in the house that require charging.
