Ryobi RY18BI150A-0 18V ONE+ Cordless Battery Inverter (Bare Tool)

What a fab gadget, made camping on a site with no electricity a doddle, especially for inflating our air beds. You must check the watts of your item are compatible for the unit, but have to say it was great and for charging our phones. You won’t be running a kettle off of it, but even the smaller batteries lasted for ages.

I bought this on a whim because it was on sale. I didn't need it, and couldn't think of a use for it when I hit the "Buy" button, but it's proved to be a really handy piece of kit. You're not going to be able to use this to run a fridge or a kettle, but it will easily power the internet modem and Wi-Fi router in a blackout, all while charging your tablet....... and being able to sit in the dark watching Netflix on my tablet beats twiddling my thumbs and waiting for dawn. :D . It will also happily run things like a Dremel and smaller power tools, so I often find myself reaching for this and a battery rather then unrolling/re-rolling an extension cord. It's one of those accessories that, if you've got it, you'll find uses for it, so if you've bought into the "Ryobi One+" brand, and usually have a few charged batteries kicking around, it's a worthy addition to your tool box.

I thought this looked like a goos idea providing you already own a few of their batteries, which I do. So now it is kept near our wi-fi router in case of a power cut. But also useful for having a three pin plug when you are out and about. However, it is expensive for what it is. But I bought it when it was on sale.

Excellent. After a recent power outage that lasted most of the day, I realised that my power bank would only charge my phone and tablet but wasn't powerful enough for my laptop, and I couldn't run my router off a power bank. I started looking for a laptop power bank but then I spotted this Ryobi battery inverter. I already have a few Ryobi one+ battery packs for my various tools, so it's the ideal solution and much more versatile than a simple power bank, as it has a 3 pin socket and the amount of time I can use it for is only limited by the number of fully charged batteries that I have to hand. I can use it to top up my laptop battery, and it can also power my router for hours on a 5ah battery and when that runs out I can swap in another battery. I could also power my furry electric blanket from it if I get cold, or power my television (not both at the same time). The only downside is that this battery inverter isn't powerful enough to boil a kettle for a cuppa!

Best buy in long time brilliant bit of kit highly recomend

It loses a star for an accumulation of small irritations. First, it works, which is great. Two USB ports which are reasonably powered (2.4A), and 150w AC out of a small device like this is pretty cool. Add a 5Ah battery and good times in a small package. Have not yet done a full test on its capacity, but I'm comfortable that it will do what I need for USB charging and a pretty bright light on full power. Downsides: The slot for the phone is angled the wrong way, so if you need the light on it's in your face instead of into the space. The power button is unreliable. It's a double click to activate the light, again to brighten it, and once more to turn it off. Timing seems critical and takes sometimes several goes to get through the changes. Also, it's a long press to activate the power features (USB and Inverter) which sometimes just doesn't register. That's the bugs The feature request, as it were, would be a way to use this as a charger for the battery. Given that the 1.5Ah charger is so small (basically just a housing around the battery terminal) I think it should have been relatively easy to fit even a 1Ah charge circuit into the space. Would have made it the mondo combo. EDIT: Got a meter on it to test, and it's not outputting at 50Hz, only 35Hz or so and not stable, ranging from 30-40Hz (same meter on mains voltage is 49.9Hz and rock solid). Best guess is that it's a modified rather than sine wave inverter, and the meter is having trouble with it. Would not trust any sensitive electronics to this. Chargers are *probably* fine. AC motor products might be tricky... See second photo. That's another star lost.

I use it for a 10 watt led floodlight when im work with dark place. Runs with 4Ah battery almost 9 hour
