I use power banks a lot and have a half dozen cheaper ones that get used in non-backpacking situations. The NB10000 is a racecar among family sedans when you compare it to the others. Rugged outdoor type power banks tend to cost about 1.5x-2x as much but most good brands in that category have real protection against rougher handling.
A Powerful Pair. Two is always better than one and with the HALO 5000 2-Pack Power Bank you and a friend can stay charged up wherever you go. The HALO® 5000 Power Bank has 5000mAh of powerful, yet it is lightweight, slim and pocketable. Recharge a smartphone up to 1.5x times on a full charge. What is the lifetime of a Power Bank? Lithium-Ion batteries used in Power Banks and smartphones will eventually lose their capacity over time (around 500 – 1,000 cycles depending on the battery size). This means that the larger the capacity of the battery, the less amount of times you will need to charge it, therefore, helping it last longer.Power Bank List. Price in BD.
