This battery looks well made and is of a standard size suitable for drop-in replacement for a variety of equipment such as low-power UPS, solar-charged lights / storage, security cameras, power wheels etc. originally designed for 12V lead acid / AGM deep cycle batteries that drain power slowly over time (max continuous discharge rate is 7A, per the manual). Most onboard 12V lead acid battery chargers in these systems will work with this battery, as they're typically designed to charge to ~14.4V -- below the 14.6V charge cutoff voltage of this LiFePO4 battery, though you'll want to make sure the charger disconnects once the max voltage is reached. Lithium chemistry batteries receive the most damage when spending a long time at high state of charge (LiFePO4 less so but still true), the opposite of lead acid batteries. LiFePO4 batteries also have a flat discharge curve and hold voltage under load better than lead-acid. Weight is 922g / 2lb by my measurement, a huge reduction compared to a similarly sized lead-acid battery. I was able to extract 99Wh from this battery after a full charge using a USB test meter (charged to 14.6V, discharged to 10V @ 8W continuous). This is significantly over the rated 92Wh. The onboard BMS appears to offer short circuit and high temperature cutoff protection per the user manual, though no mention of high / low voltage cutoff protection. I was able to discharge the battery below 10V without any intervention from the BMS; I assume the protection still exists, but at a lower voltage threshold. Cycle life is listed as >4,000 cycles at 100% DOD, which is excellent (though no mention of remaining capacity % at the end of said 4k full charge-discharge cycles, typically 80%). Overall, an excellent battery that will provide years & thousands of cycles of good service when appropriately charged / discharged.

This solar cable extension set came with a 10 gauge 20 foot wire, with MC4 connectors pre-installed on one end. The other end does not have a connector, but a set of MC4 connectors are included for you to crimp on after cutting the wire to the desired length. The set also came with a Velcro strap for cable organization or storage. Keep in mind that you will need a MC4 crimping tool to add the included connector ends to the wire. Assuming you have a crimper, this is an excellent set. The included MC4 connector was installed easily and makes a good/solid connection. The cable has a double insulation jacket, and the wire has a "6 MM" marking (meaning 10 gauge wire). A lot of sellers offer good quality 10 gauge solar cable, but I like this specific brand for the following reasons: - These solar cable sets typically come with a red and a black cable. Having a separate fully red cable is an eyesore, but necessary so you can tell the polarity. I like that this cable is mostly black, but still has a red "stripe" to identify the positive cable side. - I have multiple solar arrays, and they all feed into the same area. This means that I have quite a few "red and black" cables. If I am not careful, I could accidently plug in a red cable from one array, and a black cable from another. With this set, the cables are joined together (but can be pulled apart as needed). Keeping the cables joined allows me to easily identify the red and black cable from a specific array. Previously, I used electrical tape to keep the two wires together, but it looked much less professional. Overall really like these cables, highly recommend!

I recently upgraded my 12V 400Ah PV system to a 24V 200Ah setup using this robust and well-made inverter. After experiencing both good and bad inverters in the past, I can confidently say this one is by far the best. The design is impressive, with a high-quality finish that makes it look excellent, and it truly delivers on performance. It includes features that other manufacturers often overlook, such as GFCI outlets and specific screws for attaching AC power, which is essential if you plan to add an electric breaker box. Given that it can handle 3000 watts, having proper protection is crucial to prevent overloads, although the inverter also comes with its own overcharge protection. Moreover, it offers multiple ports, including USB and USB-C, for fast charging devices. The onboard screen displays vital information such as voltage, output in watts, and state of charge (SOC). Overall, I think this inverter is fantastic. I'm genuinely happy with it, and I believe the price is more than reasonable for the quality it provides. I would definitely recommend it.

I told them how well they work in my system, however I have no room in my system to use them so remember it is just a logical review of if I could do it in my system of how well it would work. By the way North town aside they are working great and the repair area is back up and operating 100% with the replacement panels. The power is used for the lifts in their bays.

Bought this solar panel to charge my new EF ECOFLOW Portable Power Station RIVER 2 Pro. I was able to connect it and charge the generator. I give it a 4.5 stars since I never got close to getting 200 watts of power while charging. But after reading reviews of other solar panels, I have come to the conclusion that most of them are this way. The maximum power I was able to get while charging was 144 watts on a full sunny Ohio day. The setup was easy. It took me more about 10 hours to charge it. After charging the generator, I was able to run 2 CPAPs overnight with no problem. After the $100 off tugapower.net coupon, I paid $200. Recommended!

This emergency electric backup is new to me, but I was quite impressed with this unit. I was able to power my living room light, my kitchen table light and it also ran my cable modem and my Wi-Fi device. I do have Wi-Fi lightbulbs so with everything turned on, I was only drawing about 5 Watts. I purposely bought this because I just came out of a five day ice storm with no power, so far I am delighted with this unit.

This is the second one I ordered...the first one was more sturdy. Also missing a few bolts I was able to get locally. It works and does as intended but the price versus value may not be there. I will not order it again as I thought they would at least send the same product...obviously these are not the same mounts...

I increased the capacity of my RV solar system and got this 30 amp solar charge controller. Very simple to mount and connect this new controller to my solar panels and batteries. The display is best viewed directly, not from the side, but since I don't need to often check the display this is not a serious problem. If it was more visible, that would mean it is using more power from my solar system instead of delivering this to the batteries so it seems to be a fair trade off. Testing display readings with my Fluke meter shows the display is accurate.

Great solution to making that 240v socket usable with 120 appliances. Just make sure you have a NEMA 10-50 3 blade wall socket. We have one in the living room of our older home and the options have been to either not use it, or to have an electrician rewire it, nether solutions are practical at the moment. This was a good value solution to that problem. We are now able to use the outlet, and for my wife's peace of mind it obviously has the required safety protections to prevent it drawing too much power. It will split out into four outlets, two on either side. The cable is 1.5' long, which is perfect for us as it allows it to be more easily hidden. All in all it is a substantially made piece of equipment.

I ordered this for my nebulizer. The power was out one time since I received it ordered April 6th 23. The nebulizer keeps me alive wake up have to do breathing treatment 2 to 3 times a day when it’s hot in my apt without power then the anxiety of no car to go somewhere to breathe. This was a comfort when my power was out the one time. I thought this is great my nebulizer works. Still a full charge it might run my ventilator for the night time if the power is still out. The power came back on before nighttime. That night I felt a feeling of I was ok today no ambulance or anxiety. I made a great decision buying this small generator. I’m stressed watching the plug getting hot to the touch I feel I need to give it 9 hours of charge to make sure it still is at 31%. I can’t return window close it said in July. 1 star because I used it one time.

Fantastic extension cord and 120V/240V breakout box. Quality is not lacking in any way. However, in the listing, the seller advertises it contains "overload protection", specifically two 20A breakers. I opened up the enclosure to check - there is no such thing. Just 10AWG wire, outlets, and two LEDs to indicate the presence of voltage on each 120V leg. So do not rely on this thing to protect your circuits, it certainly won't. The seller needs to revise the listing ASAP. Other than that detail, it's easily a 5-star product.

I bought this 25FT Solar Connector to XT60 Cable to allow me to have my solar panels in the sun while I have my Ecoflow solar generator inside or in the shade staying cool, if I am using it outside. I was impressed how this cable was made: It has a quality XT60 plug on one end and they used heat shrink tubing to extend the protected grab area of the plug. On the other end are two MC4 connectors that are securely connected to the 10 gauge wires. I really like they used a red and black pair wires that are attached to each other for the entire distance, except the last few inches near the plugs. I have another cord for my bigger solar panels that came as separate wires which are quite a mess to deal with. I ended up zip tying them together every few feet. Being a combination Red/Black pair wire allows you to separate only the distance you need for a neat installation. The wires are clearly marked 10AWG which I got to avoid voltage drop over the distance. The wires do seem to be made of pure copper as they passed the magnetic test. I am happy with the cable I bought.

These are installed on my new emergency home solar power station. When I received the batteries the charge was 13.3 on both of them. I have another station built with a different LiFeP04 battery which I used at 1st to start up and check the system. That battery charges faster and the charge reaches 14.4v during the day. I've never been able to get the Power Queen's past 13.7v plus the voltage drops fast. I have a Lithium battery charger that I used on both batteries separately to fully charge and sync them. I let them sit hooked in parallel for 12 hours before hooking them up to the system. I'm no expert on solar batteries so I'm not sure if this is all OK. I do know that in the old Power Queen users guide had a chart showing that 13.5 is a full charge as seen on YouTube reviews. Why did that cut that page out?, I'm not sure . The lowest voltage has been 12.6 v hooked up to my inverter with the freezer plugged in. So I'm not sure if these are working properly. Only time will tell if they will be good. Update; The batteries never reach full charge according to both my battery charge status gauges. 3/4 is the best @ 13.7v under charge is the best I can get. The batteries are discharging as they are plugged into my Solar Power Board/Inverter and Freezer. I've been helping them in the morning by plugging into my charger. They run down to 12.6v at night and recharge to 13.7v at peak PV charging hours. So, I'm still not sure about them. Update2: Batteries seem to be charging better. They reached full charge 2 days over the weeked with my battery status gauges both at 4 bars. They are holding at 13.3 overnight at rest with the inverter shut off. I'm still concerned about them not hitting 14.4v while charging. Are they waking up? I don't know... Update3; The batteries are now charging normally hitting 14.5v under charge and resting at 13.3v. I can't tell you why. Whatever was preventing them from charging correctly has fixed itself with daily charge cycles. Its taken a couple of weeks for this to sort itself out...

This is a nice panel and produces 12V and 5V out of the same box. Not sure what "Calcium" batteries are, but apparently this can charge those too! Also odd is that LiON and Acid are on the same setting even though both battery chemistries have different charging profiles. Probably not a big deal as this is more of a trickle charger than a bulk charger. Worked fine, and great for a bug-out-bag or other emergencies. Just be careful as the panel itself is not flexible and can only be folder on the designated seam.

The GRECELL 120W Portable Solar Panel is awesome! It's completely weather proof which is a huge deal for me as I am taking it canoe camping so everything in the boat could get wet. It's light weight and fairly compact. The panels are fairly stiff like fiberglass. When I first opened them I thought they forgot to put the solar panels on because they are embedded in the surface of the panel. It's really cool and should makes it very durable. The panel has kickstand to hold it up but if it's windy they don't work that well, just like the other two I own. The electrical output is via 2 MC4 connectors which makes it easy to plug directly into a solar battery box. There is no USB outlet on the panel which makes sense if you want a waterproof panel. I have a Bluetti box which uses a barrel connector and it plugged together fine using the included adapters. I also have a Lucetti box but it has a XT60 solar input. So I used an MC4 to XT60 adapter cable I already had (ordered on tugapower.net of course). It also worked well to charge the battery. I tested the panel with my Solar panel multimeter and measured 117 watts on a sunny day. So it puts out it's rated power. I am VERY pleased with this solar panel!
