Tech advice on charger unit

Evening all!
putting it simply, will the item in the link below serve my purpose?
I will only be charging three MA2 batteries, very occasionally, once every blue moon.
I will NOT be running anything else from it.
I do not know enough about inputs, outputs and such to decide for myself.
This looks to me just like a power supply that i will charge at home and use when out. Correct me if i’m wrong please.

That’s 146Wh, an MA2 battery is 40Wh … so - allowing for inefficiencies - you should manage 3 recharges OK.

Since you probably don’t take the MA2 batteries much below 25%, you might even manage 4 recharges in real usage.

The main issue might be that it’s not currently available. :wink:


Thanks Dave,
Great stuff! does that mean i can recharge 3 batteries once before it’s depleted or 3 cycles of 3 batteries before depletion?

Just 3 batteries once.

40Wh per battery x 3 = 120Wh … out of a theoretical 146Wh available.

Got it cheers

The main issue might be that it’s not currently availabl
bollox didn’t see that

I think them figures are incorrect

Wouldn’t it be better to work it from the battery capacity?

My Mini 2 battery was 2250 mAh and my power bank was 10000mAh so I got 4 recharges (which I did)

The capacity of the MA2 Battery is 3500 mAh and the power bank listed is 39459mAh

So I would say 11 recharges

mAh don’t account for voltage.

Wh work irrespective of voltage since it’s a measure of power capacity.

Well we’ll soon see as although Dave @OzoneVibe saw it out of stock, it showed as in stock for me AND a £40 voucher cost 109.99 be here in a day or so.
If I get just three extra batteries charged on a day (i’ll never use more than 6 regardless) i’ll be ok with that but the possibility of up to 11, well that would be immense.
Like i said to start, it’s above my pay grade to understand the electrickery wizardry.


Power banks can range from single charge (3000mAh) to well over (20,000mAh), and most of the latest smartphones have a battery with around 3000mAh. A 10,000mAh power bank should be able to charge the smartphone up to three times and a 20,000mAh power bank more than six times.

You can calculate the approximate number of charges by dividing the power bank’s measured capacity against your phone’s stated capacity. The outcome is the total number of charges.

You will get 10 easy but it will degrade over time, I just checked and it’s in stock, nearly bought it myself :grinning:

That will work for sure… have a look also at the Refurbished version/like new of the Allpowers unit. £109…
I just bought the refurbished 1092wh version which is normally £899 and I got it for £399, and it looked brand new, original stickers and packaging and it is amazing… charges in 3 hours (I am not saying buy this one, I am just saying the refurb versions are fantastic… and 5 year warranty)
