Refurbished Anker 555 Portable Power Station 1024Wh LiFePO4 Battery 3 USB-C For Camping, RV - sold by Anker Refurbished Shop

These are good in theory, but an absolute nightmare when they pack up - which they do. They're £499 new - but that's with a 5 year warranty. These have only 12 months, and that's because they're likely to be repaired returns which packed up.

Try sending one back under the warranty and you'll find that it's almost impossible because nobody will transport them and Anker won't provide a return label.

I used to think these were incredible - until it ceased to produce AC power very soon after purchase.

Nice! Also worth a look at the Jackery options, for those interested in this sort of thing.
Amazon currently have 35% off (and regularly do!) some of their products.
Sure, it's less spec than above but a good price nonetheless:-

Assuming the new one costs £500 and you pick this instead: If there is just 27.2% probability this used unit (1Y warranty) packs in between just after year 1 and year 5, you're better off buying new (5Y warranty).

Honestly won't buy this without the full warranty. 1Y is okay - but paying a few hundred quid will feel like a badly sunk cost if/when it stops working 18-24month in.

By that stage, you might as well spent the extra £135 on the new from Anker with correct warranty - that offsets the risk appropriately. This item is a consumables battery item by nature in that the storage degrades (they don't necessarily get to the rated charge count, before something breaks, could be the BMS, the cell, the connectors stop charging, aka alot of unnecessary risks vs buying with full warranty).

Imo this is a worse concept than buying OLED TV used (without a longer warranty), or EV car (with shorter 1Y warranty for the battery). Similarly precarious product (say vs qled that has less burn in); at least with the TV it'll still work. If this packs in, good luck.

I mean sure this is probably only Anker managing /reselling the returned inventory that has passed their quick re-QA check following a return or similar repair process - but by only putting on 1Y warranty (vs 5Y on new), it's basically Anker spreading externalities/ spreading risks onto customers / once it packs in, it's a paperweight. A precarious purchase that'll land a headache down the road sooner than there needs to be.

Obviously for some, the cheaper price with 1Y wty makes more sense - than the peace of mind of extra warranty. But if it's 5, chances are you can hand me down it or find alternative use and use it for full 5Y. Also maybe in the future the 1KW capacity will keep getting cheaper due to EV battery overcapacity for some time to go.

Statista suggests 1kw in 2023 for cars cost approx £109. That's without a battery management system (bms), packaging, shipping, R&S, marketing, etc. So there is room for these to probably get to £200 - maybe 250 not too far from now.

Got this last time it was on offer, very impressed with it, came as new in the original box etc. Picked up a 100w folding/portable solar panel from ecoworthy and they are working together fine.

Although the picture says 5 year warranty, I checked and it only comes with 1 being a refurbished unit. Im not too concerned given the price, just info for others.

Don't need. Want. Don't need. Want. Don't need. Want

I see they're doing a Best Offer on these. They also have loads of the things to shift - including the one I returned when it packed up!

Which does make you wonder why so many pack up!

Says it's £379. Am I missing something or have they just put the price up?

Im wondering can I take one of these in my car. I wait for long periods of time in my car, that’s just my job. I have a gaming laptop with 270w brick but I think without charging it draws something around 150w. Can I use one of these and for 150w how long this battery will last?

As suspected. Absolutely brand new and just excess stock.
