Belkin Power Pack 4000

Belkin is famous for its mobile accesory product line and the Power Pack 4000. While this is not the most powerful in this group, it can deliver a fast charge to two devices.

According to the Belkin product page, the Power Pack has pass-through capability, meaning it can charge phones and tablets at the same time that it charges its internal battery. This means it can be used in place of a phone/tablet power adapter.

From the Belkin product page:

  • 4000 mAh power for charging on the go
  • Allows four full cell phone charges, two full smartphone charges or a full tablet boost
  • Built-In Safety: Thermal Management, and Over-Current and Short Circuit Protections
  • StorageSafe technology holds 95% charge up to 30 days
  • Convenient charge indicator
  • Two 6” USB to micro-USB cables for charging and recharging
  • Wall adapter

$99.99

  • Summary

    What would be a good addition to these and other similar presentations would be, IMHO, a summary grid as the last slide, showing a comparison of the attributes/specs of each device. Just my 2 cents ....

  • It's taken you 3 years to catch on James

    I was already recommending the Energizer XP8000 back in 2010, and it charges netbooks/notebooks as well. Folks can google "lifestyles of the mobile road warrior" for the article on all-day power.

  • Are these really worth the money

    I looked in some anticipation at these chargers. I have many devices and every so often am caught out with that thriller-like feeling that I haven't enough battery for the trip home.

    I have android stuff, so basic universal charger stuff by the way

    But it seems to me you would have to be so badly organised or be carrying 27 devices to need any of these. Not only that, you would have to make sure your charging device is charged as well as your chargers. Far better to bring a normal dual plug and a couple of USB cables or if you buy a phone, like the Samsung, get a spare battery on eBay for $5. Really not worth spending the 100 bucks on a device which you are just as likely to forget as a spare charger or battery.

  • I think...

    ... ALL remote batteries and chargers should have fold out solar cell panels for recharging itself.
    Then again, why not have solar panels on the backside of laptops and notebooks?

  • Ridiculous!

    This is THE reason I'll never buy a phone without a removable/replaceable battery.

    I travel for work, and the last thing you want is to be across a foreign city, maybe needing to use your GPS to navigate back to the hotel, and having to plug in some big, expensive, external dongle to rip your suction cup mount off your windshield. Totally unacceptable, Rube Goldberg workaround to the fundamental problem:
    YOU bought a phone without a removable battery.

    By contrast, I can keep a charged battery in my pocket (which is tiny), and just pop it in anytime I want, and I'm back to 100% charged. Instantly.

    Also 'by contrast', I bought two 2200mah batteries (stock is 2100 on my phone) and an external charger for $15 with free shipping on Amazon... meaning I have a total of three batteries, so I can keep one in my laptop bag, one in my phone, and one in my pocket so I'm never stuck without that weird thing I'm otherwise likely to "oops, left that in the hotel room...".

    Just boycott phones without removable batteries. Vote with your wallet, and stop jumping through hoops. It's how manufacturers will get the message.
    They build products to suit customer demand... so stop buying products that don't suit ALL your potential needs!

    • missing your logic

      So, your phone sits on the suction cup of your car, but you have to charge it with external battery, instead of the car's battery?

      Then, you prefer to keep an fragile and dangerous spare battery in your pocket so that you could install it when in need?

      If you only have one phone, of known brand that that brand does not change their batteries over time (all of them do!), possibly you could do it "your way".

      But if you happen to have several gadgets, each of which has apparently very different battery, then you will carry N different batteries, correct? Or N*2 batteries, just in the case you use one of the devices more.

      Then, those two batteries + charger for $15 things: that is guaranteed junk. If you put any value in your phone, you would not put a battery like this inside...

      But then, it's your money and your devices to waste.

  • And yes, I mean $15 total for all three...

    Well - looks like it's up to $18.xx with free shipping now, a year later:
