How many times can I use this? I understand some solar powered devices eveuntally run out.

Hi Jasmine, These solar chargers can last forever depending on how well you take care of it. You can expect close to 10 years of efficient performance but with our 100% customer satisfaction if you ever have any problems with possible internal wiring issues, or some possible damage of the panels, we guarantee to fix the situation for you. Hope this answers your question.

We reused them. You can't reuse them A LOT but if you are careful you can get 2-3 times out of them

I dont know. I have only used mine once when the electicity was out. I haven't even tried charging mine with the solar panel. I keep it plugged in.

Throwing in my two cents. Get two for this. It'll work fine for awhile for you the way you want to do it, but ultimately, your battery is going to lose charge 'cause you will be running close to max on the panel all things considered unless you are in bright sunlight all the time. Plus, over time, your battery is not going to charge as efficiently. My 100W Grape tests at 5 amps in good sunlight. But then there's nighttime....:-) I run an off grid system, and am going to get a second panel just because of those cloudy days. An MPPT controller will help maximize your charging too. I haven't gotten one of those yet. Throwing in my two cents. Get two for this.

We'll I don't know how many times u wanna use it !!! Any product u use for lot of time it will wore out !!! But this product is worth of a purchase . I have been using this for almost a year . And I use atleast once in 2 weeks . It's worth it for the price that I paid for

You can use them many times until they wear out. I have had no issue with multiple uses.

You could use it multiple times. I would get the bigger one if you plan on using it for that amount often.

Your equation is going in the wrong direction. What do you need to run and for how long are the first questions. Then, figure out the whatever you need to power that. Whatever you need to go with it is also important. What kind and how many batteries are you going to charge over how long a period. Think of it like this: The solar panels are like funnels that collect electricty for your solar well which are your batteries. Bigger or more batteries equal a bigger well. Once full, a small funnel will keep the well topped off. But, if you have a big well, or use it often, you'll need a bigger funnel to collect more electricity more quickly. Essentially, the battery soaks up the juice so you can accumulate battery power. Then, you can then hook up an inverter of what ever Watts to run your stuff on for ever how long the battery will live under that drain.

The charge is different for everyone. Depends on how much you use it and what you do with it. When I use my camera several hours at a time I find I need to recharge daily, but if you don't plan on using it a lot 3 should be OK. You might look into a solar charger. I don't think they are very expensive.

You won't know. If you use it a lot, you probably should just count on charging it once a week.

There is no easy access to replace the batteries. But, as with all devices and tools that use lithium-ion or lithium polymer batteries, they are fantastic for a couple a thousand cycles of charging, minimum. That would mean you can charge them three times a say for several years without a problem. I can't see anyone using them that much. I hope the information helps.

Depends on what you are going to use it for. If you are going to use your Setup for Emergency Lights, Battery Chargers, Small Appliances the Inverter you use will draw harder off of the battery the more devices you use. I use one 50 watt Solar Panel, Charge Controller, Inverter and two of these Deepcycle 35aH batteries for power outages, emergencies etc. A Small Solar Panel will just trickle charge the battery and you won't be able to use it for powering much before it drops down to the minimal low voltage. A 50 watt Solar Panel is probably a good starting point, then go from there as to what you need to meet your needs. Depends on what you are going to use it for.

Yes you can use another solar charger. I charge mine with the anker 14W dual USB port solar charger. And I have both energizer brand and the goal zero AA that came with it. They both work great.

It's not solar powered. I don't use mine much, so the batteries last quite a while. For constant use, they last about 12 - 24 hours.

Just one. I found I get about 1 hr. 15 continuous use. I don't use it this way, so usually get about a week of on/off use. FYI my first lasted about a year and without warning It would'nt take a charge.Because I'm generally pleased witth it replaced it without any hesitation.

Rommel, I agree with Tim. It depends on what you are going to use the stored power for. For example, on average you will charge the batteries 10A for six hours or 60aH. If you are running a water pump that pulls 5A for 15min every hour you would need approximately 30Ah to run 24/7. In this case one battery is more than sufficient. In my case I run LED worklights and cameras. I pull about 10A for 8 to 10 hours which adds up to approximately 100Ah per day. Taking battery degradation and the fact not every day is 100% sun, we use two batteries. Hope this helps with your scenario.

It is self powered so I do not see why you could not, although I am not sure how many you could do total.
