User questions & answers

Question:	Will this charge two deep cycle battles at the same time
Answer:	I don't know where the 2 other comments came up with one amp output. Minimum is 5.1 amps with mttp controller. Still insufficient to fully charge deep cycle flooded battery with much load.
Question:	Are there any directions with this item? also, do i peel off the plastic coating? it is all bubbly like i should, but i am not sure
Answer:	No, there are not really any directions but it’s pretty simple to use. Yes, peel off the protective plastic layer. I know it looks like it is attached underneath the fabric but it comes pretty easily.
Question:	how long will it take with good sunlight to recharge a dead 12v automotive battery
Answer:	The right answer is: It won't. 5W is the absolute best these cheap panels will output, in reality you will only get about 1W during daylight hours, mostly due to thermal derating. The charge will be so minimal, that battery leakage at night will eliminate any small charge you get during the day.
Question:	Does this have a blocking diode
Answer:	I don't believe this panel has a blocking diode built in as CX wrote in 2018. Can seller confirm whether there is a blocking diode built into the panel? Thanks

• Requires several hours of direct sunlight every day. Ability to recharge varies based on device settings, motion notifications and sun exposure in the area of placement.

User questions & answers

Question:	Does this work with the basic ring camera with no spotlight
Answer:	The original stick up camera uses an older micro USB port. It was not the best outdoor solution and allowed moisture into the camera. The current stick up cams use the plug in connector that his water resistant. This should fit the newer spotlight camera and stick up camera. The older style solar charger is available on the Ring page.
Question:	How long is the cord
Answer:	13' as specified. I have purchased a couple of these. The cord is 13' and accounting for some slack needed both a the light placement and the solar panel, the panel and the spotlight can be placed 10-12' apart (The camera and light placed for the view and coverage needed but the solar panel positioned for the best exposure to the sun eg. south). Mine works very well.
Question:	Confused. There are several answers.... How long is the cord from the camera to the solar panel... Answers vary from 1.5 ft to 12 feet
Answer:	It’s right there in the description where it says POWER CONNECTION at the bottom I pasted it here for you.

Question:	what is output voltage and amperage
Answer:	Per Ring Spec Sheet: The Solar Power Rating is 6 Volts, 2 Watts. This calculates to 0.33 Amperes.... The power P in watts (W) is equal to the current I in amps (A), times the voltage V in volts (V).... or Watts = Amps times Volts... or Watts divided by Volts = Amps 2 Watts / 6 Volts = 0.33 Amps Note, output is dependent on your Sunlight Environment.

User questions & answers

Question:	Is it water resistant
Answer:	Yes
Question:	Q: When the charging process is interrupt by cloud or trees will the charging countinous automatically or must i plug out and plug in the smartphone
Answer:	Ive found that the device you're charging has more to do with the restart or not. My easyacc power banks restart on their own when connected to my Aukey and Nektek chargers, but my cheaper power banks wont. They need to be separated and replugged each time the wattage changes. (From a cloud, shadow etc)
Question:	How long does it take to charge
Answer:	there is no battery inside the panel, so the time it takes to charge your device is depending on the capacity of your device.
Question:	Can you connect an inverter to this
Answer:	think the question was asked to learn about the system...inverter would not be necessary due to the lack of power being converted to ac..

Sunway solar battery trickle charger maintains the 12 volt battery of car, truck, marine , motorcycles , tractors, ATVs, snowmobiles, boat or RV.

Why do I need a solar trickle charger?



Three reasons to own a Sunway Solar Battery Trickle Charger:

• Batteries Naturally Discharge - Automotive batteries naturally discharge when not in use.
• Vehicles have a small but constant battery drain - Modern vehicles have upwards of 30 body control modules (computers), alarm systems, immobilizers and lock monitoring. These units all consume electricity from the battery. That's why in a week or two with no or little vehicle use the battery can become discharged.
• Battery life is shortened if it is not kept charged - A 12V battery that is not correctly maintained above 12.4V can suffer from sulphation. Sulphation is the main cause of battery failure. That's why the auto battery easy goes to dead when vehicles are left standing for long periods.

User questions & answers

Question:	Could i use this to keep my phone charged when i camp out for star wars seats
Answer:	I just come back from camping and this solar panel works great i charge 2 cellphones and a 10 inch table and battery backup in direct sun light charge faster
Question:	could i use both usb ports on the solar panel to maximise charging to one device? any built-in intelligence to combine both USB ports when one is used
Answer:	Solar panels are rated for the best possible case of 1,000 w/m2 solar irradiance. I tested this panel in N CA using a Pyranometer to measure the actual solar irradiance over a range of conditions and electronic instrumentation to measure the solar panel's actual output wattage. In summary, even in summer over the case of a day, the solar irradiance averaged about ½ of the maximum possible and the output of the panel averaged 10.82 watts. That input to a USB battery is 2200 mAh at 4.92V. As long as the USB battery used supports this range of input, it will utilize the average potential of this solar charger.Average solar radiation for a location on the northern hemisphere with a latitude angle of 47° - 55°:sunny, clear sky summer: 600 - 1000 W/m² - Wattage rating for a panel is 1000 w/m2winter: 300 - 500 W/m²sunny, scattered clouds or partly cloudysummer: 300 - 600 W/m²winter: 150 - 300 W/m²cloudy, fogsummer: 100 - 300 W/m²winter: 50 - 150 W/m²The EasyAcc Monster 20000mAh Power Bank (4000 mAh Dual-Input specification but, I measured a max input of only 1830 + 1640 = 3470mAh using two 2.4A inputs). It will only charge faster than a conventional battery of similar capacity, such as Anker PowerCore 20100, using a dual wall charger capable of outputting a minimum 2.0 amps out each port or a much larger solar charger that will average 3470 mAh over 6 hours of the day needed to charge the battery. That will not happen using the Anker 21W solar panel which will average ~2200 mAh over 6 hours of summer sun. The single input port Anker batteries will closely max the average output capacity of the Anker 21W solar panel.I frequently correspond with thru-hikers who need to quickly charge battery capacity in the 20000 mAh range. Historically I have suggested a dual 2.4A wall charger in combination with 2 Anker PowerCore 10000 batteries. The measured output on the two ports is 2,600 mAh each. This combination weighs 3 oz. less than a single EasyAcc Monster and provides redundancy to protect against a battery failure. The charge rate for 20,000 mAh aggregate capacity is faster because both inputs accept 2100 mAh versus what I measured on the EasyACC Monster of 1830 and 1640 mAh.
Question:	Does this product offer any kind of rain resistance? Can it be used outdoors in a rainy day
Answer:	I left mine outside on a covered porch, up on a chair. It did get wet, not drenched soaked, and it won't work. I'm going to call the company though because I never even used it (this was my first time "charging" it and we got a freak rain come through) and I want to make sure I'm even doing it correctly and didn't just get a bad one. If I did everything correctly, I won't be purchasing another one!
Question:	I bought Anker's massive 26,800 mah battery the one that comes with Qualcomm Quick charge 2.0 was wondering how long it would take to charge with this
Answer:	Just a quick note: Anker has TWO PowerCore 26,800 mAh batteries in production (as of 2/2017). One includes a Qualcomm QC 3.0 compatible charging port (& 2 PowerIQ ports), but has only one micro-USB charging port for the battery pack itself (https://www.amazon.com/Anker-PowerCore-Portable-Ultra-High-Capacity-Recharges/dp/B01N3TVRP2). The other loses QC 3 (it has 3 PowerIQ ports), but gains an additional micro-USB charging port for decreasing charge time for the battery pack (https://www.amazon.com/Anker-PowerCore-Portable-Double-Speed-Recharging/dp/B01JIWQPMW). If you are looking for fastest possible charge time for a battery pack while camping, I would recommend you choose the latter model for use with any of these portable solar panels (all of which have two USB connections, as far as I've seen).
