![]() An informative display: Though most portable power stations have a battery meter so you can see how much charge you have left, we preferred displays that provided an estimated percentage of the charge over vague displays that consisted of just a few line segments.Handles are a necessity to lift something this bulky, and since in some cases you’re going to be moving these around quite a bit and using them outdoors-in a backyard or at a campsite, for example-we wanted them to be resistant to scuffs and scratches. A rugged and portable design: We assessed the quality of each portable power station’s exterior materials, as well as any extra features like wheels or handles.Anything heavier than that can be hard to load and unload from a car, or to carry around a house in a blackout. But even so, we set a weight limit at 50 pounds, a heft that one (strong) person or two people could reasonably carry. A maximum weight of 50 pounds: Most portable power stations are too big and heavy for the average person to carry them for long distances on foot.Lower outputs are fine for charging phones and most other electronics, but if you want to charge a few devices at a time (especially if one is a high-powered device like a laptop), you need 100 W or more. An output rating of at least 200 W: To separate the portable power stations from their smaller, less powerful counterparts ( USB power banks and portable laptop chargers) we required each of our main and budget contenders to be rated for at least 200 W, and we wanted the lightweight (under 5 pounds) contenders to be rated for at least 100 W.When it comes to batteries, capacity is king. We made this a requirement for our main picks, and strongly preferred it for our budget and lightweight contenders. (For a variety of reasons, less than 100% of a battery’s designed capacity is actually available for use.) Put another way, that’s like running a 60 W device-such as a MacBook Pro, projector, or tabletop fan-for five hours. A battery capacity of at least 300 Wh: A watt-hour (Wh) is literally the measure of watts per hour, so a battery with a 300 Wh capacity offers the equivalent of running a 300 W device for one hour.Find out what Ah people commonly have for an on board battery pack, then you can see what cells suit and how to wire them. You can get cells with little metal tabs so the soldering is easier, safer. Normally the cells were soldered together. ![]() Making up packs is quite easy if you have some basic experience with electrinocs, soldering etc. Maybe a smaller one if you don't really need 5-7Ah ? If you are just exploring on your own then naving two batteries is probably ok. You can put it in a bum bag (money belt). If you don't have any familiarity with really basic electrical stuff then the cheapest option is probably the 12V gell cell (bike battery). I need it to be with 4 pin XLRĬonnection and at the same time to have original connector to charge it using original charger. I saw some people convert DeWalt 12v batteries. At the moment I'm using a motorbike sealed battery, but it's heavy and it takes long to charge it. Hi, please help me build battery for 16mm Kinor 16 CX 2M. Of course, this is very much a homebuilt approach, and probably won't have the reliability of off the shelf batteries, but it's probably the cheapest way to go if you don't mind a bit of construction work. ![]() What's more, they run from 12V, so you can charge in your car. They can handle NiMH, NiCd, lithium, and even lead-acid batteries, and have a lot of programmable features. Also, you aren't allowed to take them on aircraft unless they have passed expensive safety tests.įor charging, I have had good luck with chargers like this. ![]() They could work, but they require a lot of complex electronics to work really well and have a short life, even if you don't use them. I don't know if this would be adequate for your camera since NiMH is not as good at high current loads as NiCd, but you could do the same with bigger cells, and use NiCd rather than NiMH.Īvoid lithium ion cells. I'll simply use a plastic project box (I haven't bought those yet), and 12 cells per pack to create a 14.4V, 2000mAh battery. I actually have some parts here now that I bought to do this with - these NiMH cells (that's a very good price, as they are high quality cells), some normal battery holders, and miniature volt meters. I've done this a few times and it's a fairly low cost way to obtain batteries. If I wanted to do that, I'd just buy some nickel cadmium or nickel metal hydride cells and put them in a box with an XLR on it.
