10 Handy Travel Power Banks For Trippers
Types of power banks
There are mainly three types of power banks which can be classified as:
- Standard power banks: These type of power banks is most common and use cables to charge or discharge power, for which port are given.
- Solar power bank: They can also be said “green” power banks as they have solar panel embedded in them to recharge them. Which saves power.
- Wireless power banks: These types of power bank are of the latest technology as they do not need cable to charge the device. The mobile can simply be put in the charging area and the charging starts. Also, the device should support wireless charging.
Type of Battery Used
Power banks mainly use two types of batteries i.e. Lithium-ion and Lithium-polymer. Both have their benefits.
A power bank must be sturdy and durable as it will be used outdoors a lot. Even some new type of power bank is waterproof.
Size and Weight
Your power bank is designed to be portable; otherwise, what’s the point? With this in mind, the physical size and weight of it will be major factors in considering which one is right for you.
Inputs (1A, 2A, or 2.4A)
At some point, your power bank will need charging up to ensure it can provide the backup charge power you need. What you want is a nice, quick recharge speed that means you can get back out there without having to be attached to a wall socket for hours on end.
A power bank should be of high quality and should be able to withstand high load and demand. The batteries should be of good quality and the input and output ports should be sturdy.
The power capacity that your power bank kicks out is measured in milliamp-hours or “mAh.” The amount of mAh available will define how much charge you can expect to get out of your power bank.
- Most airlines will cap power banks at 20,000 mAh while some will allow larger. Always check with your airline what the maximum capacity requirements are.
- Newer power banks can be charged even more quickly with the addition of a 2.4A input option.
- Lithium-ion batteries are cheaper but can have a limited capacity, whereas lithium-polymer are generally more expensive, but are better in terms of capacity and longevity.
- If you want your power bank to operate as best as possible, you should be sure to use it fairly regularly.
- Just like many electronic devices, power banks perform best in normal or neutral temperatures.
- Most phones need a current input of 1 A to charge, while larger devices might need up to 2.1 A to charge. As a result, you need to find a bank with the right input current for the device you want to use it for.

- Re-charge cycles
There are two types of re-charge cycles and they determine whether your power bank is good on or just an average one. A good power bank has 500 re-charge cycles while an average power bank only has 300 recharge cycles.
- No 100% storage
Some of you might think that your power bank holds 100% of the power capacity if you max-charge it, but you are wrong. The average ones only hold up to 70% of the power capacity; good ones might hold up to 80%; while awesome ones can hold up to 90%. This is due to a thing called discharge efficiency.
- Difference between good and average
Do you want to know which power bank is good and which one is just average? Here’s one way. Good power banks sell in real capacity while average ones are sold in marked capacity. That’s the reason why a good Power Bank can charge more or about the same as an average Power Bank despite having a lower capacity.
- Two types of Power Banks
There are two types of power banks; the lithium-ion Power Bank and the Li-Polymer Power Bank. Their main is the kind of electrolytes they use. A lithium-ion Power Bank uses liquid electrolytes while the Li-Polymer Power Bank uses solid electrolytes. Next time, if you are unable to tell which is which, just remember the electrolytes.
- mAh and Wh misconception
Used to measure the electric charge of the power bank, most people refer it a milliamp, but It is an entirely different thing. Its proper name is a mill-ampere hour. Likewise, for the measure of electric energy of the power bank, it is not Watt, like what you learnt in physics class, but instead, it is known as Watt-Hour. Those who know physics would know their relationship but for those who don’t, here is a free physics lesson about their connection.
