Would it be okay to just charge the bank up once and keep it for whenever I'd need it? Or does the charge slowly decay?

The charge very rapidly decays. Unless you use the thing as a charger where it will charge both your phone and itself when it's plugged into the wall all the time I'd avoid this all together. It's a good wallet sized charger but don't expect it to hold a charge

The Charge slowly decreases over several months. I have tested it several weeks after being charged and the power bank is fully charged. However, I have tested it 3 months after charge and it was drained to 0%. It seems that it should be plugged in every 4-6 weeks or so overnight and then carried safely for another month or so.I still carry mine, but as it only has a small charge, and the higher capacity power banks are cheaper and just a little bit bigger, I carry those now instead as they can charge my phone 10 times, and my tablet 2-3 times. This small charger only added about 20 minutes of battery to my phone and about 10 minutes to my tablet. The Charge slowly decreases over several months.

I only had it a month but the charge gave me like 10% on my galaxy s5 after just sitting and maybe playing with the led light a few times. doesnt seem to go fast if it does

The charge does decay. If you charge it over night it could get you out of a pinch during the day.

I've only charged it once after the initial charge, since I received it early in December. Of course we don't use it constantly.

I haven't had any problems with it holding a charge. I have noticed if I don't use it for a few days it doesn't work. So I would suggest charging it every other day or so. If mine is charged it usually lasts a couple hours.

Definitely around that amount. I usually charge around once a week and it charges in about 1 to 2 hours.

That is not its intent. I don't believe the battery would last very long always being on charge. Plus, depending on the size of the pump, it wouldn't last very long: 5-8 hrs..

My plan was to let it charge for 24 hours, but it seemed to work right away. I ended up forgetting about my plan and using it even before it had charged for 24 hours, and it worked fine. I have had this for a few months now with no problems. I have even had the phone with me for several hours while being on call for work, and it has stayed charged.

The unit doesn't indicate whether it charges and then reverts to trickle and I haven't checked with test equipment to determine if this is the case. I can say that the instructions indicate that it is ok to keep it on continuous charge. There is a built in fan to cool the charging circuit. I suspect, but cannot confirm, that it does revert to trickle after a charge. My unit is 2 years old and works fine.

if you have a starting and acc. battery and a trolling battery, use the two bank charger. pull in,plug in and forget it. after charging full it goes to maintenance mode.

yes I left it charged for about 12 hrs the first time. after that the time gets shorter.

Yes, it does need to be charged, but it lasts for quite a while before needing to be charged again.

I would not expect to see it lose charge for one or two weeks. But if you are at home, just leave it plugged in. The circuits will protect it, it will not overcharge.

I've had mine a while. I usually keep it in my purse for emergencies. The longest I think I've kept it without using it was about 2 weeks and it was still charged, so I'm sure it can last longer (I just haven't had to test it for more than that).

I have had one charged and waiting to be used for a couple months and it's still fully charged so I would charge them in case there is a problem with power conversion overseas.

I use the bank to charge multiple devices at once too. I have found no real difference. I suggest you save the money and buy the older (bank) one. I still use mine daily and love it!!!

I keep mine charged all the time, that way its always at its best speed. It runs down if not charged in.

I charge mine regularly about 3 to 4 times and then I let it drain down completely and I've never had a problem yet.

Good morning-I use mine for school for charge it on a weekly basis (every Sunday) but I haven't noticed a huge decrease in charge over a week even if I don't use it during the week (10-15%). Hope this helps.
