For most people, smartphones and tablets are pocketable computers. Apart from voice calls and messaging, we also use our smartphone as a digital camera, gaming device, internet browser and for several others different tasks. But the biggest drawback of almost every mobile device in the market today, is its limited battery capacity. Some of the most popular and high-end smartphones, don’t even last half a day of heavy usage. The solution? A portable Power Bank that is capable of charging your mobile phone or tablet multiple times.
It was the ‘Mi Power Bank’ from Xiaomi that transformed the Power Bank market, when they launched a 10000 mAh power bank for less than 1000 rupees. Since then, all other manufacturers have started offering equally good or better portable chargers for an affordable price.
Here are some key things to check before buying a power bank:
- Milliampere hour (mAh): The higher the mAh number, the longer your power bank will last. A good quality power bank with 10,000 mAh or more of battery capacity should be able to charge your smartphone around 2-3 times. Since tablets have larger batteries, your power bank should be able to fully charge it once.
- USB Ports: If your power bank has one USB port, it can charge one device at a time. If it has two USB ports, it can charge devices at the same time (for example, smartphone and tablet).
- Size and weight: While we highly recommend that you purchase a power bank of 10000 mAh or more, lower mAh power banks are usually lighter and easier to carry. So if portability is important, buy lower capacity power banks.
Note: We have tested and used Mi Power Banks. They offer excellent value for money and are high quality products too. But buying a Mi product can be frustrating because most of their products are always out of stock. Also, the other major issue is duplicate Mi products. They are everywhere!, including local stores and online stores like Rediff and Indiatimes If you want to buy a Mi Power bank, we suggest that you buy it either from Flipkart or the official Mi.com website.
The other power banks that we have listed below are equally good and some of them offer better features.
1. Ambrane P-1310 13000 mAh Power Bank – Rs 900
We have been testing this for about 2 weeks now and the power bank has worked flawlessly.
- 13000 mAh, you should be able to charge your smartphone 3 times (minimum) or more. We tested it with the Xiaomi Mi 4. We could charge it 3 times completely and there was still some battery left in the Ambrane Power Bank.
- It takes around 6-7 hours to charge the power bank completely using a 2.1 amp charger. Note: Some lower amp chargers (like those charging adaptors that come with budget mobile phones) might take more time to charge the power bank. So if your power bank is not charging within 10 hours, then check the charger that you are using to charge it.
- Two USB ports to charge two devices simultaneously.
- LED Torch
- LED indicator
- The weight is on the higher side. Might be difficult to carry in your pocket for a long time. But with 13,000 mAh of battery power squeezed in, you can’t expect the product to be light weight.
2. Honor 13000 mAh Power Bank – Rs 1500
We tested Honor’s 13000 mAh Power Bank for 3 days and didn’t encounter any major issues.
- 13,000 mAh, you should be able to charge your smartphone 3 times (minimum) or more. Again, we tested it by charging the Xiaomi Mi 4 smartphone. It could charge the phone completely 3 times and then drained completely after the Mi 4 was at 20% on 4th charge!
- Charges fast, took us around 5-6 hours to charge the power bank completely using 2.1 amp charger.
- Two USB ports
- Metal design. Good built quality.
- LED indicator
- Again, weight was an issue. Most power bank with capacity of 10000 mAh or more, will feel heavy in the pocket.
3. ADATA PT100 10000mAh Power Bank – Rs 900
We have been using this for a few months, without any issues.
- 10000 mAh, should be able to charge your smartphone 2 times (minimum) or more. We tested it with Xiaomi Mi 4. It was able to charge the phone 2 times and then went upto 35% on third charge.
- Charges pretty quickly. Took us a little less than 5 hours to charge the power bank completely using 2.1 amp charger.
- LED indicator
- ADATA is promoting it as a power bank that is easy to grip and from our tests, yes, it was comfortable to hold.
A lot of people ask us, how many times can a good quality 13,000 mAh power bank charge smartphones from different brands. Dividing 13,000 mAh with the battery capacity of your smartphone, won’t give you an accurate figure, because about 20% of power is lost for various reasons. The article would get too technical if we get into details, but here are some approximate figures of how many times you can charge your phone with 13,000 mAh power bank.
- iPhone 6 (1810 mAh battery) – 5 charges (even iPhone 4S, 5 and 5S should provide 5 full charges)
- iPhone 6 Plus (2915 mAh) – 3 charges
- Samsung Galaxy S6 (2550 mAh) – 4 charges
- Xiaomi Mi 4 (3080 mAh) – 3 charges
- One Plus Two (3300 mAh) – about 3 charges (could be a little lesser than 3 full charges)
- Asus Zenfone 2 (3000 mAh) – 3 charges
- Moto G 3 (2470 mAh) – 4 charges
- Nexus 5 (2300 mAh) – 4 charges
- iPad Mini Retina 3 (6470 mAh) – 1.5 charges (i.e one full charge + 50% second charge)
- iPad Air (8600 mAh) – 1 full charge
