    Never get these?. 200w is a phone or laptop charger, that's it really
    _stan's avatar
    I bought one for my summerhouse, I run a TV & firestick from it, I get about 5-6 hours run time from it so lasts all evening. Does the job until I eventually hard wire or put solar in there.

    I bought the 240Wh Jackery Battery (similar to this) with the 80W solar panel. Perfect for camping off Grid. It kept my Electric cool box cool all weekend long. And also had some charge to charge and Ipad and a few phones when the sun was shining.

    Same setup as me for camping. I use mine to charge devices, inflate boat/bed, coolerbox etc

    Don't know what people are expecting to do with it looking at some of these comments, it wont charge a Tesla...

    An awful lot to spend on a battery that stores about 7p worth of electricity.
    plewis00's avatar
    It is. It's for convenience. The extra cost seems to come from being able to output at higher voltages and currents not the battery capacity - even though it's LiFePo4 based. If it was down to Wh only, it's around £40 worth of cells.

    Something I absolutely don’t need but want because I have a fascination with power banks and portable off-grid power.
    definitely gets it

    Though I am tempted to DIY it.

    I do . But I usually don't spend such amounts,

    No, you couldn't. There's no regulator/charge controller for this function so you could end up frying the battery or possibly ruining the unit itself.

    Would be perfect for charging an E-Bike
    dookes1974's avatar
    This is only 256Wh, most e-bikes have a battery that is at least 500Wh, so you would onyl get 50% charge at best.

    Tempted by this but I feel there must be a newer version around the corner. Having 1 usb c and 2 usb a ports seems a little outdated and there appears to be a smaller version that has the newer screen and 2 usb c ports

    My feelings exactly. Nice idea, but much better and cheaper ones coming.
  8. shtivshtiv's avatar
    For anyone looking for a portable power pack like this you should be made aware of the Ecoflow River 2 series. They cost 80 quid more but they fully charge in 1 hour and have 300w output (with a surge of 600w).

    You might still want to go with the cheaper option but someone here might appreciate knowing what's out there.
    tenohfive's avatar
    This is going to sound pretty pretentious, but the thing I miss most when camping is my coffee machine. I'm guessing that if the specs of my espresso machine say 1600W, the River 2 wouldn't run it?

    ive got a few of these.. great gadget to have .
    very handy
    Ewen_Bruce's avatar
    I'm intrigued. What do you use them for?
  10. peteorb's avatar
    Will this run my Motocaddy golf trolley
  11. muon's avatar
    Anyone tried running ghds off of this?
    plewis00's avatar
    What are the GHDs rated for?
  12. Kiririn's avatar
    Apparently this can be used as a mains UPS, which makes it a lot more interesting
    plewis00's avatar
    It's expensive if you want to use it primarily for that function though. As long as it doesn't damage the cells by constant trickle charge.
  13. MRBFR's avatar
    I saw one of these on Insta yesterday, complete with solar panel. Looks fun for camping instagram.com/ree…A==

    Very odd this was to pop up - I bought one on these off facebook marketplace just a few days ago

    Very happy with mine (edited)
  15. backyard's avatar
    I can run my 40" TV for 3.5hrs with this. Won't run my PC and TV though, the power spike from the PSU is too great. Ran a TV and laptop fine though. Playing Minecraft really started to suck the juice. Kids enjoyed knowing they were playing on free (excluding purchase of panels and batter) solar power. (edited)

    Random question. But how many times can I charge an iPhone on this?
    plewis00's avatar
    Assume the battery is around 12-16Whr (let's average at 14) and this is 256Wh with 70% effective capacity (after losses to heat, efficiency, conversion, etc.) - so 256/14 * 0.7 = roughly 12.8 times
