Keep your smart devices juiced up on the road; always. We tested eight power banks to see how far they’ll take you on a road trip from Jozi.
Before you buy
Capacity is indicated by the milliamp hours (mAh) – the higher the number the more juice it can provide, but it’s also likely to be more expensive, bulkier and require longer charge times (often overnight). Note that a power bank will not always deliver its full capacity because energy is lost through heat and voltage conversion. As a ballpark figure, roughly 2500 mAh is required to fully charge a smart phone (an iPhone 5c for example).
The output and input rating of power banks is indicated in amps – higher amps mean your device (output) and the power bank’s battery (input) will charge faster. Note that some tablets cannot charge at all from low-amp devices.
Test conditions
To test, each power bank was fully charged on mains power and plugged into a flat TomTom GO 5000 – a nifty GPS device available for R4399 at Cape Union Mart. We then used each power bank on a trip from Joburg to surrounding areas to record the length of time it kept the GPS juiced up. For example, the 2600mAh Powerstick powered the TomTom for three hours and 35 minutes, all the way to Ladysmith.
1. 2600mAh Powerstick
R250, capeunionmart.co.za
Gets you to: Ladysmith (3 hours 35 minutes)
Weight: 200g
Input: 0,5A
Output: 1A
Warranty: One year
Notes
The Powerstick’s power level stayed at four for a long time, but dropped quickly from three to zero. This unit is great for single-charge emergencies and, compact and light, can live in your backpack or handbag.
2. Energizer 5600mAh Power Bank
R449, makro.co.za
Gets you to: Hoedspruit (5 hours)
Weight: 151g
Input: 1,5A
Output: 2,4A
Warranty: Two years
Notes
A good-looking, palm-size unit (if a little dumpy) that has good capacity for its affordable price and dual USB charging ports. No frills here.
3. Red-E Powerbank 6000mAh Premium Edition
R389, actiongear.co.za
Gets you to: Pietermaritzburg (5 hours 15 minutes)
Weight: 131g
Input: 1A
Output: 2,1A
Warranty: Lifetime
Notes
A sleek well-designed unit with dual USB ports, it can charge three devices simultaneously. I’ve owned one like this for the past year and take it everywhere. Exceptional value for money and the only unit we tested with a lifetime guarantee.
4. 6000mAh PowerTraveller Powermonkey Explorer 2 Power Pack
R1299, duesouth.co.za
Gets you to: Howick (4 hours 30 minutes)
Weight: 286g
Input: 2A
Output: 2A
Warranty: One year
Notes
Ultra-tough, compact, water-proof and shock-proof, this baby belongs outdoors. Both the digital percentage indicator and the extra-length cables are examples of good design, but at a cost. The only thing I was bleak about is that it didn’t fit nicely back in its box after use.
4.1 2200mAh SolSave My-Powa Solar Battery Charger
The SolSave My-Powa Solar Battery Charger is a similar but more affordable option at R500 (Outdoor Warehouse), but only has a 2200mAh capacity, which will get you to Bela Bela (2 hours 10 minutes). 10 hours of sunshine will also fully charge the unit.
5. 12000mAh GP Portable PowerBank 302C
R599, glagencies.co.za
Gets you to: Three Sisters (8 hours)
Weight: 250g
Input: 2A
Output: 2,4A
Warranty: One year
Notes
This unit charges two devices at once. It also has a 2A input so charges quite quickly. A fair price for its capacity, it’s particularly good for charging tablets.
6. Modern Innovation 16000mAh Power Bank Charger
R825, powerbankcharger.co.za
Gets you to: Touws River (11 hours 40 minutes)
Weight: 350g
Input: 2A
Output: 2,1A
Warranty: One year
Notes
The slick aluminium alloy shell is the same as that of the MacBook Pro. This is a good option for the design-conscious, but it took a while to charge up compared to the others listed here.
7. Lenmar Mutant 20800mAh Portable Power Pack
R1699, be-akin.co.za
Gets you to: Anywhere in South Africa (ran for over 20 hours)
Weight: 493g
Input: 2A
Output: 2,4A
Warranty: One year
Notes
This is the big daddy. It’s amazingly compact for its capacity, but too heavy to pack for a hike. Best used for camping or as a charging station at home.
Did you know?
You can buy a power bank with enough juice to jumpstart your car? The Boltpower Auto Jump Starter G06 boasts 16500mAh, weighs just 1,2kg, comes with a special set of 12-volt clamps and can start up a dead battery. It can also be used to power a compressor. Pretty neat huh?
